The bandwagon momentum generated by the Giants’ signings in spring training was incalculable both in terms of clubhouse excitement and among the fan base, which suddenly sees their team as a playoff contender.

Unlike Snell, Chapman and Soler, who fans have seen as established major leaguers on other teams, there is an air of mystery regarding Lee, given that his entire career has been in the KBO League in South Korea.

Fans at Oracle Park got their first look Tuesday night at what Giants manager Bob Melvin hopes is a regular occurrence — with Lee batting first and playing center field against the Athletics in the second game of the Bay Bridge Series.

It was a quiet Oracle debut. Lee went 0-for-3 with a strikeout to see his spring average drop to .343 and had no challenging plays in the field. Not that a 3-1 Bay Bridge Series “let’s get it over with” loss will have any bearing on expectations from the fanbase or teammates.

Lee, 25, makes his major league debut on Opening Day Thursday in San Diego, where he’ll face Padres ace Yu Darvish.

“The first guy of the game is going to be Lee and the guy on the mound is going to be Darvish, so I think everybody’s going to be looking forward to that,” Melvin said.

If Lee’s ability transfers seamlessly from the KBO to the MLB, the Giants will have themselves a pesky table setter who can run the bases and is an above-average flyball chaser in a ballpark that demands it.

Lee’s teammates have gotten a close look at him during spring training, and like what they see for reasons that go beyond a .375 batting average and 1.176 OPS with a homer and six RBIs in 12 games, coming into Tuesday night’s game.

“I mean he’s a terrific bat-to-ball player,” catcher Tom Murphy said. “His skill level is unique in that way. You don’t see too many guys that strike out so few times as Lee does. Other than that, he looks like a supreme athlete, a go-getter, a cool, calm, collected player who is going to have a huge year for us.”

Lee’s credentials in South Korea included being named Rookie of the Year in 2017 and Most Valuable Player in 2022 with a slash line of .349/.421/.575 with 23 home runs and 113 RBIs in 142 games. Lee played in 85 games before an ankle injury ended his season and required surgery.

He checked out well enough medically for the Giants to sign him to a six-year, $113 million contract.

From what outfielder Michael Conforto has seen, it was a sound investment.

“He’s a very polished player, has a knack for putting the barrel on the ball,” Conforto said. “He’s got lightning-quick hands. He’s fast, a good athlete and knows the game. I could go on and on about what we’ve seen in the spring. I think we’re all going to be real impressed by him.”

Outfielder Mike Yastrzemski believes “having a steady anchor in center field is huge” and said Lee has been a joy to have in the clubhouse.

“One of the best things is he’s really, really, down to earth and a great teammate. So it’s going to be great to have him in this locker room.”

Shortstop Nick Ahmed, a slick defender with two Gold Gloves, said he could tell right away Lee was skilled in that area.

“He’s got great baseball instincts,” Ahmed said. “I can always tell as a shortstop, when I turn around, the difference between an outfielder who freezes and takes a second to read the ball or if I can see his back turned and see his numbers and he’s two steps into his break. He’s going to be a great center fielder or us with the big gaps in this park.”

Offensively, Lee, who struck out just 304 times in seven seasons in the KBO with 383 walks, could quickly drive up some pitch counts.

“He’s a pest at the top of the lineup and he’s somebody opposing pitchers are going to hate, seeing him foul off pitches and staying alive,” Ahmed said.

From what Melvin has seen, stereotyping Lee as a slap hitter would be a mistake.

“He doesn’t strike out, and it’s not like he’s just poking the ball,” Melvin said. “I expected maybe a little bit more of that, especially with two strikes, but he takes a pretty healthy hack. He just moves it over a little bit with two strikes and is thinking the other way, but still takes a good hack and stays away from strikeouts. He’s very unique.”

As far as blending in with his teammates, Melvin has been impressed in that regard as well.

“He just loves playing baseball,” Melvin said. “He was comfortable since Day 1 in spring training in a new country, new people, new environment. I’ve had to deal with quite a few guys that have done that. I don’t know anyone that has fit in as quickly as he has.”

YAZ ON HOLD: Yastrzemski was in the lineup after a false alarm the previous evening as his wife is expecting a baby. Whether Yastrzemski will be around for Opening Day or on paternity leave is an open question.

“Anything’s on the table as far as that goes,” Melvin said.

REPLACING THE BRANDONS: Ahmed, the likely starting shortstop, has one of the clubhouse lockers closest to the door. It was the locker previously occupied by Brandon Belt, with the departed Brandon Crawford’s locker right next door.

Ahmed, who played in Arizona from 2014 through 2023, has no illusions about taking Crawford’s place in an organizational sense.

“I got to play against Brandon for a long time in this division,” Ahmed said. “I respect him a ton for what he did for this organization. I’m not coming in trying to replace him or take his job or anything like that, just going to be me and help us win as many games as possible.”

It was at that point the crowd of 27,706, Giants and A’s fans alike, as well as the home dugout, rose in unison in celebration of the iconic “Panda” who likely played his final game with the organization that first brought him to the major leagues in 2008.

Sandoval even rewarded the fans with a broken bat single in his final at-bat, the start of a rally that saw the Giants score their lone run in the ninth of a 3-1 loss to the Athletics in the Bay Bridge Series.

Rather than send Sandoval out initially, Giants manager Bob Melvin waited and then sent Sandoval into the game to get his proper due.

Talking with reporters before the game, Melvin wouldn’t divulge how he would use Sandoval but did say he expected a large ovation.

“I expect it to be immense,” Melvin said. “It has been all spring long and I wouldn’t expect it to be anything different. Especially here. Got a plan for him.”

Sandoval got standing ovation No. 2 with two out in the sixth, facing relief pitcher Austin Adams with the A’s leading 3-0.

He wasn’t going up to the plate to walk.

Sandoval fouled off four straight pitches before striking out on a foul tip. As he walked to the dugout, Sandoval received his third standing ovation.

Leading off the ninth against right-hander Vinny Nittoli and the fans chanting “Let’s go Panda,” Sandoval rose to the moment by punching a broken-bat single to right after seeing seven pitches and swinging at six. He was removed to yet another standing ovation.

The Giants closed to within 3-1 on an RBI single by Joey Bart, but got no further.

In all, Sandoval saw 13 pitches and swung the bat 11 times.

“Whatever it takes to get that hit,” Sandoval said in the postgame clubhouse. I’ve always been a free swinger . . . I had one more opportunity to wear this uniform this year. Had great fan support. I don’t know if it’s my last at-bat here but it was unbelievable. Getting the hit was the most important thing — not for me, for the fans.”

The Giants have not yet announced whether Sandoval would remain with the organization, perhaps playing in Triple-A Sacramento, or be released at age 37. Sandoval has expressed a willingness to go to Sacramento, but hasn’t yet spoken to president of operations Farhan Zaidi.

“Everyone thinks I’m retired. I’m not,” Sandoval said. “I want to continue playing . . . I’ll talk to him, see what’s going on.”

Sandoval played with the Giants from 2008 through 2014 — on three world champions — and again as a spot pinch hitter and reserve from 2017 to 2020. He said his favorite memories were his first major league home run against Livan Hernandez, his three home runs in Game 1 of the 2012 World Series against Detroit, the three World Series championships, pitching a scoreless ninth against the Dodgers in 2019 along with his probable finale Tuesday night.

The drama of Sandoval’s final at-bat was not lost on his teammates.

“It was awesome to see a guy that’s had such success in his career here to be fighting for that hit,”  right fielder Mike Yastrzemski said. “That’s as fun as baseball gets.”

In 571 games at AT&T Park (the name of the Giants park for most of his Giants tenure), Sandoval hit .302 with 66 home runs and 288 RBIs in 571 games.

Sandoval played two seasons with the Atlanta Braves and spent the last two seasons playing in Mexico, Puerto Rico and Venezuela.

Returning to the Giants for spring training, Sandoval was 5-for-25 (.200) coming in with no home runs and two RBIs.

A’s manager Mark Kotsay feigned anger for Sandoval taking away a hit opportunity with a defensive gem, of all things.

“All that comes to mind when you say Pablo Sandoval is my last game here as a San Diego Padre, my first at-bat of the game, I hit a line drove — smoked a line drive — and he laid out and caught it,” Kotsay said. “My last chance to get a hit in a big league game and he stole it from me.”

Kotsay said the decision on whether or not to play is best left to the individual.

“A lot of times guys ask me, when did you know it was the right time to take the uniform off?” Kotsay said. “I always say, you’ll know when it’s the right time. The game will tell you. Obviously Pablo doesn’t feel that way. My advice is always to make them take it off. I think he’s one guy that’s going to make them take it off him.”

The Giants wrapped up spring training Tuesday with a 3-1 loss to the Athletics at Oracle Park, with their cross-bay rivals salvaging a split before a crowd of 27,706.

The team took on a different look during spring training, especially with the late additions of third baseman Matt Chapman and left-handed pitcher Blake Snell in free agency. Other newcomers include center fielder Jung Hoo Lee and designated hitter Jorge Soler.

The Giants were blanked by A’s starter Paul Blackburn for 5 2/3 innings with the biggest cheers coming for Pablo Sandoval, who isn’t expected to be on the 26-man roster when they open the season Thursday in San Diego against the Padres.

After striking out in his first at-bat, Sandoval hit a broken-bat single to right in the ninth. He was removed for pinch-runner Donovan Walton, who went to third on a single by Wilmer Flores and scored on Joey Bart’s single to left center.

The Giants had a rally in the eighth when Austin Slater singled and went to third on a one-out single by Ismael Munguia, but Otto Lopez grounded into a double play against Tyler Ferguson.

The Giants trailed 3-0 in the sixth on a sacrifice fly by Nick Allen, whose flyout scored Lawrence Butler, who triple to lead off the inning off Camilo Doval.

A sacrifice fly to shallow right by Esteury Ruiz scored Butler from third to put the A’s up 2-0 in the top of the fourth.

Butler opened the inning with a single, and after a flyout, Allen hit a roller down the line that third baseman Matt Chapman thought would roll foul. It didn’t. A walk to Darell Hernaiz loaded the bases, and Ruiz hit a fly to Yastrzemski in right. Yastrzemski’s throw was on target, but Butler made a nice slide and tagged home with his right hand to score the run.

The A’s scored the first run against Blayne Enlow, the third Giants pitcher, on a run-scoring ground out from designated hitter and former Giants third baseman J.D. Davis.

Carlos Perez opened the inning with a one-out walk and was doubled to third by Ryan Noda, with Davis plating Perez with a ground out to Nick Ahmed at short.

Spencer Howard, a right-hander from their minor league camp who started the game, pitched 1 2/3 innings but departed after he was struck by a line drive off the bat of Allen. Chapman fielded the ball at third and threw Allen out at first.

After a visit from the medical staff, Cody Stashak, another pitcher from the minor league camp, replaced Howard. Howard sustained a right upper arm contusion.

Edge rusher Leonard Floyd participated in a teleconference with local writers, officially signing a contract a week after agreeing to terms. Not long after the call was concluded, the agent for quarterback Joshua Dobbs reported on Twitter/X that Dobbs was joining the 49ers on a one-year contract.

There was no official word from the 49ers, but a source familiar with the situation said the plan was for Dobbs to join the team.

Floyd, 31, is coming off a 10 1/2 sack season in Buffalo.

“I talked to Nick once I committed,” Floyd said. “We’re eager to play with each other . . . I’m looking forward to getting out, doing my job and just being a professional.”

Dobbs, 29, was a starter for Arizona while Kyler Murray rehabbed from an ACL tear, and then was dealt to Minnesota as a starter after Kirk Cousins tore his Achilles’ on Oct. 29.

Having already re-signed Brandon Allen, last year’s No. 3 quarterback behind Brock Purdy and Sam Darnold, Dobbs gives the 49ers three quarterbacks after they played all last season with Purdy, Sam Darnold and Allen.

In 13 games as a starter for Arizona and Minnesota, Dobbs completed 62.8 percent of his passes (262-for-417) for 2,464 yards, 13 touchdowns and 10 interceptions in addition for 421 yards on 77 carries and six touchdowns. He had four games with a quarterback rating of better than 100 — including Oct. 1 at Levi’s Stadium for Arizona when he was 28-for-41 for 265 yards and two touchdowns in a 35-16 loss to the 49ers. Going into the 49ers game, coach Kyle Shanahan praised Dobbs’ play.

“He’s been extremely decisive. When it’s there, he consistently makes it, when it’s not there, he plays it smart, doesn’t turn it over,” Shanahan said. “He has been able to scramble and makes some plays. He’s been very competitive in the quarterback run game when they haven’t honored him.”

In Week 3, Dobbs engineered a 28-16 win over Dallas by going 17 of 21 for 189 yards and rushing for 55 yards on six carries. Dobbs won his first two starts in Minnesota before struggling and he didn’t play from Weeks 14 through 17.

Floyd said the 49ers were an easy choice because of their status as a Super Bowl contender and that they “didn’t B.S. around . . . It was a great deal, a solid deal for me and it really wasn’t no second-guessing it. They showed they wanted me from the jump. Once I saw that, I was like, shoot, I want y’all too so I’m on my way.”

Ideally, Floyd becomes the first outside running mate of Bosa to break through with double-digit sacks. The closest thing Bosa has had to a consistent outside threat on the other side was Dee Ford in 2019, who had 6 1/2 sacks in 11 games in 2019.

Excluding 2020 when Bosa was injured, the second-highest sack total from an edge rusher to Bosa was Samson Ebukam in 2021 (4 1/2), Charles Omenihu in 2022 (4 1/2) and Clelin Ferrell last season (3 1/2).

Chase Young, who had 2 1/2 sacks this past season during his nine games lining up on the other end of the line from Bosa, got a one-year deal for $13 million from New Orleans, according to ESPN.

Floyd’s deal was reportedly for two years and $20 million.

“I knew this was a team that was ready for a Super Bowl run,” Floyd said. “I didn’t want to go to a team and be in a position to not play in the playoffs. So I came here with aspirations of coming in, helping the defense out to win games and get back to the big games.”

Floyd’s sack total of 10 1/2 tied his career high of 10 1/2 in 2020 with the Los Angeles Rams. At 6-foot-3, 240 pounds, Floyd has played both outside linebacker in a 3-4 defense as well as edge in a 4-3.

“It really don’t matter to me as long as we sack the quarterback,” Floyd said. “It don’t matter, standing up or there-point. Scheme-wise, I’m an athlete so I’ll fit any scheme. All I need is for my coach to teach me what to do and where to go and I’m going to go 100 percent.”

Floyd played from 2016 through 2019 with the Chicago Bears and worked under new 49ers assistant Brandon Staley in both Chicago and Los Angeles.

The 49ers named Nick Sorensen as their new defensive coordinator in place of Steve Wilks, with Staley hired in an as yet undisclosed capacity.

“Coach Staley, man, that’s my guy,” Floyd said. “I been knowing coach Staley since my second year in the league, so it’s been a long time and he knows me too. He knows the type of player I am and what I bring to the table.”

Floyd hasn’t missed a game since 2016, having played a full schedule in each of the last six seasons and attribute his relentless nature to working watermelon fields from the ninth through the 12th grade in Georgia.

“That’s real hard labor. It teaches you to grind, it teaches you real hard work.” Floyd said.

Campbell, who was an All-Pro with Green Bay in 2021, was signed by the 49ers after being released by the Packers and provides insurance alongside Fred Warner as Dre Greenlaw rehabs a torn left Achilles’ sustained in Super Bowl LIV.

Yiadom worked his way into the lineup for the last eight games for New Orleans last season and had his best season with 14 pass breakups. He’ll compete to play behind Charvarius Ward and Deommodore Lenoir. Ward is entrenched as an outside corner, with Lenoir available either outside or as a slot corner.

Lucas, who played the last two seasons with Detroit is regarded as predominantly a special teams player, as is Ezekiel Turner, a linebacker who led Arizona with 12 special teams tackles. Turner’s signing has yet to be confirmed.

A former third-round pick out of North Carolina A&T, Parker played 59 games with 33 starts as a right tackle for the Raiders but never had a stranglehold on a starting role.

The punishment amounts to a slap on the wrist for this year’s draft from April 25-27 in Detroit. Instead of picking at No. 131 overall, the 49ers were pushed to the very end of the round following compensatory picks at No. 136.

It gets a little more painful next year with the forfeiture of a fifth-round pick.

The 49ers issued the following statement regarding the sanctions: “We take responsibility and accept the imposed discipline from the NFL due to a clerical payroll error. At no time did we mislead or otherwise deceive the League or gain a competitive advantage in connection with the payroll mistake.”

The 49ers have 10 selections in this year’s NFL Draft, starting with the No. 31 overall selection in the first round. They have three picks in the fourth round, including No. 124, which they received from Dallas in exchange for quarterback Trey Lance, and two picks in the sixth round.

But Aiyuk is not going to do that any more than Nick Bosa was going to play for $17.5 million a year ago on his fifth-year option, which means the 49ers will be negotiating a big-money extension with one of their best players. It’s why there is rampant speculation — a small amount merited, much of it social media-fueled nonsense — that the 49ers are open to trading either Aiyuk or fellow wideout Deebo Samuel.

The 49ers made Bosa the highest-paid non-quarterback in the NFL with a five-year extension worth $170 million with $122.5 million in guarantees and an average salary per year (APY) of $34 million. Aiyuk won’t get that, but the 49ers and every other team have a ceiling in mind when it comes to putting together a roster puzzle.

Recent deals with wideouts Michael Pittman of Indianapolis and Calvin Ridley likely have Aiyuk tantalizingly close to that limit. Pittman, who was originally given the franchise tag from the Colts, agreed to a three-year $70 million deal which works out to $23.3 million APY. Ridley, who signed with Tennessee after a strong year with Jacksonville, got $92 million over four years and $23 million.

Here is how the three fared in 2023:

Aiyuk: 75 receptions, 1,342 yards, seven touchdowns, 17.9 yards per catch.

Pittman: 109 receptions, 1,152 yards, four touchdowns, 10.7 yards per catch.

Ridley: 76 receptions, 1,016 yards, eight touchdowns, 13.4 yards per catch.

Aiyuk is younger than both at age 25. and is still an ascending player. (Ridley is 29, Pittman 26). He’s the most explosive of the three and put together a highlight reel that included one of the plays of the year against Detroit in the NFC Championship Game with a 51-yard catch that hit the facemask of Kindle Vildor. His tape includes downfield blocking the likes of which the 49ers demand but you don’t often see elsewhere.

If all three were on the open market, it wouldn’t be close. It’s Aiyuk going away. The 49ers surely realized they would have to come in over $20 million in APY on an extension, but are they willing to go to $25 million or more? That’s probably what it’s going to cost.

The following are the five NFL wideouts with APYs of $25 million or more according to OverTheCap.com: Tyreek Hill of Miami ($30 million), Davante Adams of the Raiders ($28 million), Cooper Kupp of the Rams ($26.7 million) and A.J. Brown of the Eagles ($25 million). All are between 27 and 31 years old.

The 49ers can pay it, cap be damned. The salary cap went up to $255.4 million this year, which helps. Quarterback Brock Purdy is bound by the collective bargaining agreement to play his third season under the terms of the deal he received as the final pick in the 2022 NFL draft at a salary of $1.1 million before being eligible for his own extension. As for the rest of the cap, Fred Warner George Kittle, Javon Hargrave and Kyle Juszczyk have all reportedly agreed to restructures so they’re clearing the decks for putting together the roster.

The truth of it is, getting Aiyuk aboard with an extension will likely decrease his cap number from $14.1 million this season because the bonus money will be prorated and the first-year salary will be low. The problem will be in future years when the bill comes due for Purdy.

As general manager John Lynch directs Paraag Marathe in assembling a salary structure, there’s another thing to consider. The 49ers are already paying Samuel an APY of $23.850 million on an extension negotiated after the 2022 season that wasn’t all hearts and flowers. Samuel missed all of the offseason, removed 49ers logos from his social media and didn’t sign until Aug. 1. And although Samuel ultimately got paid, he had a so-so season in which he said he was “awful” in part because he wasn’t in top shape.

Samuel mostly escaped criticism for this until coach Kyle Shanahan called him in and provided video evidence. Samuel rebounded somewhat last season and was even named a team captain. But the fact remains that Samuel will never approach his 2021 numbers again and no team in the NFL will come close to tying up somewhere near $50 million APY for two receivers.

And that’s not even factoring in running back Christian McCaffrey, who doesn’t reach a void year until 2026 at an APY of $16 million and is the reigning NFL Offensive Player of the Year (translation — most valuable non-quarterback). Running backs aren’t rewarded in the current pay scale hierarchy, but if I’m McCaffrey’s agent, the circumstances are unique in that he’s almost as valuable as a receiver as a runner and he’s no worse than No. 2 on the offensive pecking order behind Purdy.

It’s a lot to consider, especially considering the 49ers like to say they’re positioning their salary structure for the future as well as the present.

Don’t be surprised if the amount of time it takes to figure out what to pay Aiyuk drags on until August or later as the 49ers gear up for 2024.

As for what the 49ers will do in terms of cap structure if Purdy has another year resembling 2023, that’s a dilemma to solve a year from now and one of those problems any team would love to have.

De’Vondre Campbell, an All-Pro as recently as 2021 for the Green Bay Packers, has agreed to terms with the 49ers on a one-year contract.

The 49ers also agreed to terms with Isaac Yiadom, a seven-year veteran who played in 17 games for New Orleans last season with eight starts. Yiadom’s agency, VaynerSports, announced the one-year contract on Twitter/X.

Campbell, 30, was released Wednesday by the Packers before a roster bonus of $2.97 million came due. He signed a five-year extension with Green Bay in 2021 worth a maximum of $50 million but missed 10 games due to injury over the past two seasons.

The deal with the 49ers was confirmed by a source familiar with the negotiations and was first reported by NFL Media.

The 49ers had previously reportedly agreed to terms with free agent Eric Kendricks of the Los Angeles Chargers, but Kendricks backed out of the deal and signed with the Dallas Cowboys instead.

Greenlaw, who sustained a torn left Achilles while running onto the field in the 49ers’ 25-22 loss to the Kansas City Chiefs in Super Bowl LIV, had surgery and there is no timetable for his return. Given the seriousness of the injury and the normal recovery time, Greenlaw’s status for the early portion of the season in particular is in doubt and getting him up to full speed could be a year-long project.

An eight-year veteran out of Minnesota drafted in the fourth round by the Atlanta Falcons, Campbell (6-foot-3, 232 pounds) has played in 115 games with 110 starts. After missing three games with an ankle injury last season, Campbell took to social media to express frustration about playing hurt.

Coming to the 49ers provides an opportunity for Campbell to get his career back on track after a disappointing season that included a social media blast against the Packers.

“I’m not playing through injuries anymore cause when (stuff) goes wrong they always use it against you,” Campbell posted on Twitter/X last Dec. 23.

Yiadom, 27, will compete for a role at corner, where the only sure things are starters Charvarius “Mooney” Ward and Deommodore Lenoir. He has also played for Denver, the New York Giants, Green Bay and Houston before joining the Saints.

Coming off his best season with his second career interception and 14 passes defensed, Yiadom made the Saints in training camp, played on special teams, then fared well when injuries forced him into the lineup. He finished with 37 tackles, 25 solo and one fumble recovery.

Oren Burks, who started when Greenlaw dealt with injury issues during the season, remains an unrestricted free agent. The 49ers confirmed the signing of linebacker Demetrius Flannigan-Fowles, which was first reported by the Associated Press.

Others who reportedly will return include guard/center Jon Feliciano (Fox Sports), while wide receiver Chris Conley is also working toward a deal (NBC Sports Bay Area).

The 49ers also reportedly agreed to terms with cornerback Chase Lucas, a two-year veteran who played exclusively on special teams for Detroit last season.

“I don’t think you replace a person like Arik Armstead, the person he is in the community, the person he is on the field,” Maliek Collins told local reporters Thursday on a conference call. “I’m just here to add my skillset and bring who I am to the table.”

Collins, 28, arrived in exchange for the first of the 49ers’ two seventh-round picks in the 2024 draft. The 49ers also confirmed previously reported deals with defensive tackle Jordan Elliott and Yetur Gross-Matos to two-year deals and a one-year contract to bring back Kevin Givens.

The 49ers have yet to announce the signing of edge rusher Leonard Floyd.

Joining Armstead on his way out from the 49ers is Ray-Ray McCloud, a wide receiver and return specialist who reportedly agreed to terms with the Atlanta Falcons.

None of the exits come as a big surprise, as Armstead’s lack of availability due to repeated injuries made his $17.4 million salary and $28.4 cap number problematic. Armstead, the longest-tenured 49er at the time of his release, played in 21 of 34 regular season game the last two seasons due to knee and plantar fasciitis issues.

Armstead played 859 snaps for the 49ers over the last two seasons while Collins was playing 1,302 snaps for Houston.

According to Bleacher Report, Armstead will get $51 million over three seasons in Jacksonville, where the general manager is Trent Baalke. Without signing bonus money or guarantees made public as of yet, it’s hard to know if that figure is truly representative of what Armstead will earn.

Baalke was the GM in 2015 when Armstead was a first-round draft pick. Collins presumably is much cheaper than Armstead should he have elected to take a pay cut, with two years left on his current contract with $8 million guaranteed this season.

At 6-foot-2, 310 pounds, Collins comes in with a lower center of gravity than the 6-foot-7 Armstead. He is coming off his best season in terms of sacks (five) and quarterback hits (18) under DeMeco Ryans, the former 49ers defensive coordinator.

“DeMeco called me to inform me the trade had went through,” Collins said. “I was grateful for that. I think that just showed his character, that he would call and break the news himself. We said our thank yous and he said I couldn’t be going to a better organization with great people.”

Collins, a former third-round draft pick by Dallas out of Nebraska in 2016, played four seasons with Dallas and one with the Las Vegas Raiders. He has spent the last three with Houston and has had his eye on 49ers line coach Kris Kocurek since meeting with him at the 2016 NFL Scouting Combine when Kocurek was with the Detroit Lions.

“I’ve actually been waiting to be coached by him my whole career,” Collins said. “I met with him a lot during the combine process back when I came out and I’ve come full circle.”

Collins came out the same year as Hargrave, and said the two work out together in the offseason.

According to The Athletic, a straight trade of Collins for Armstead was scuttled when the Texans instead signed edge rusher Danielle Hunter.

“I’d heard there’d been a couple of talks,” Collins said. “My agent had called me and when the Texans had informed him it could be a possibility. What a great place to be, though. A place that’s had a lot of success, a storied organization, I couldn’t ask for a better situation. It did come as a surprise, but I’m super excited to be here.”

In two seasons with the 49ers, McCloud caught 26 passes for 378 yards and a touchdown in 29 games. He missed five games due to injury in 2024. The 49ers’ primary punt return specialist with 57 punt returns for 559 yards over two seasons, McCloud had a broken wrist at the start of the season and missed time with a fractured rib later in the season.

In the reality that is 2024 NFL free agency, getting Leonard Floyd for a reported two years and $20 million looks like a winner in terms of both common sense and business sense.

Danielle Hunter of Minnesota, whose last contract prohibited the franchise tag, was speculated as top target for the 49ers, as well as bringing in Joey Bosa to pair with Nick, or perhaps Khalil Mack. Both Chargers edge players are under contract, Bosa for $15 million in 2024 and $17 million in 2025, and Mack is owed $17.5 on the last year of his deal.

We’ll see what Hunter brings in, but it’s likely well exceed Floyd’s number. And there’s no telling what Joey Bosa and Mack would want in terms of a contract upgrade if traded or even released to be a free agent.

Floyd comes in at a rate where he can be strictly a situational rusher. He’s 31, but hasn’t missed a game due to injury since 2018 and had 10 1/2 sacks from the edge for Buffalo last season. It was the most since he had 10 1/2 for the Rams in 2020 when his defensive coordinator was Brandon Staley, who is now on the 49ers staff as a defensive assistant.

The 49ers didn’t stop at Floyd. They also agreed to terms with Yetur Gross-Matos from Carolina, a 25-year-old edge who was a second-round draft pick from Penn State in 2020, on a two-year deal worth a reported $18 million. Gross-Matos arrives as more of a developmental player than Floyd, given that he’s played a full season just once in four seasons and has 13 career sacks.

Considering the edge market, with Brian Burns getting traded from the Jaguars to Giants and getting a five-year, $150 million deal and Jonathan Greenard (Vikings; four years, $76 million) and Bryce Huff (Eagles; three years, $51 million), cashing in on big deals, Floyd’s deal is the kind of short-term, produce-now acquisition for a team that has been either in the Super Bowl or a step away in four of the last five seasons.

Eight other observations as the negotiating period in free agency got off to a lightning start with no signings official until the start of the new league year on Wednesday:

— The door was finally officially closed Monday on the Kirk Cousins-Kyle Shanahan reunion that has been speculated upon since the two worked together in Washington under Mike Shanahan in 2013.

It was pretty much shut once the 49ers determined they’d hit the lottery with Brock Purdy, because up to that point, Shanahan’s eye may or may not have been wandering in the direction of Cousins. Cousins broke the bank when he agreed to a four-year contract worth as much as $180 million with the Atlanta Falcons. He’ll average $45 million per season and was guaranteed a reported $100 million.

All for a quarterback who will turn 36 in August, was already limited in terms of mobility and is coming off an Achilles’ tear.

The scary part for the 49ers comes next season when Purdy becomes eligible for an extension. See those contract numbers for Cousins? A year from now, Purdy could match or exceed those based on his 2024 season. Then in terms of assembling a roster, it’s a whole different ballgame.

— Keep the fates of Arik Armstead and Aaron Jones in mind the next time you hear a coach or G.M. extoll the virtues of character, integrity and a team-first mentality. The 49ers defensive tackle and the Packers running back were deified by their respective organizations right up to the point where they got too expensive or didn’t fit in with the plan. Now they’re looking for new homes.

— Running backs are on the move — Saquon Barkley from the Giants to the Eagles, Josh Jacobs from the Raiders to the Packers, Devin Singletary from the Giants to the Vikings. and Austin Ekeler from the Chargers to Commodores. None will approach Christian McCaffrey’s $16 million average salary.

And McCaffrey’s a bargain. He got bypassed in terms of APY (average per year) by Deebo Samuel last year and he could get passed by Brandon Aiyuk this season assuming an extension is on the way.

— Tight end Charlie Woerner (three years, $12 million) departed for Atlanta to take what he’s learned from George Kittle and go out on his own and show he can do more than just block. Woerner or no Woerner, the 49ers need a second receiving tight end threat to go along with Kittle, and it’s impossible to know whether 2023 picks Brayden Willis and Cameron Latu are up to it.

— The open market looks better in terms of safeties than corners, with the 49ers looking for both if they’re not bringing back Tashaun Gipson Chauncey Gardner-Johnson (Detroit), Kamron Curl (Washington) and Justin Simmons (Denver) are available to pair Ji’Ayir Brown and a recovering Talanoa Hufanga.

As for corners, Xavier McKinney got a four-year, $68 million from Green Bay, which in the post-Ted Thompson era is actually signing free agents. Look for the 49ers to extend Deommodore Lenoir and find another corner in the draft or a fringe free agent.

— Putting a second-round tender (at $4.9 million) on Jauan Jennings means he’s unlikely to get an offer sheet since the team that signs him would have to give the 49ers a second-round selection. It qualifies as putting their money where their mouth is for a player who epitomizes their commitment to physicality among their wide receivers.

— Sam Darnold would seem to be a natural to wind up in Minnesota replacing Cousins. The 49ers brought back Brandon Allen if that’s the case. But if Darnold is left standing in the game of quarterback musical chairs, there are worse jobs than being Purdy’s backup.

— History suggests to be very skeptical when it comes to the Raiders and free agency, and just because they hitched their wagon to Garoppolo last year. Pairing defensive tackle Christian Wilkins (Miami) with Maxx Crosby looks like a master stroke from a distance.

But things aren’t always as they seem with the Raiders They won 12 games in 2016 after signing Rodney Hudson the previous year and then Kelechi Osemele. But their history is littered with wasted dollars on the likes of Tyrell Williams, Sean Smith, Gibril Wilson, Lamarcus Joyner, Maliek Collins, Cory Littleton and others.

Yet here’s an annual reminder as media coverage for expendable players goes wall-to-wall as free agency begins  — let the buyer beware. The brightest shiniest items should go quick — a Kirk Cousins here, a Danielle Hunter there, even a well-worn Tyron Smith. Teams can enter into agreements with players on other teams today at 9 a.m., but nothing official can happen until Wednesday.

The earlier they agree, the bigger the contract. The better deals will come later, when the lawn is clear and the garage door is about to be shut for the night.

History tells us the 49ers will be on the lookout for one expensive item that fills a need, then fill gaps with the rest. If you’ve been to the NFC Championship Game four times in five seasons, won it twice and have your star players under contract, it says your roster is in good shape whether you’ve won a Super Bowl or not.

The 49ers will be good again and chances are they’ll be in the same place come January of 2025 as they were last season: In the playoffs, with a chance to either appease their fan base with a championship in New Orleans or leave them disappointed and bitter over yet another near-miss.

You can already sense the grumbling on social media when right tackle Colton McKivitz got a relatively modest contract extension (through 2025 worth $7 million and $4.5 million in guarantees). McKivitz was perceived as a weak link all season but wound up being solid enough to make 17 starts and play 1,040 snaps — the most on the team.

McKivitz isn’t going to make any All-Pro teams and he’s not Trent Williams. His pay suggests if some stud right tackle became available either in free agency or the draft, he could change positions (guard) or roles (swing tackle).

Signing McKivitz isn’t a sign of weakness, it’s a sign of a 49ers team that has a clue about how to go about their business. Coach Kyle Shanahan and general manager John Lynch haven’t been perfect since they arrived seven years ago in rebuilding the franchise after the Jim Harbaugh/Trent Baalke dynamic imploded and begat Jim Tomsula and Chip Kelly.

But here’s what Shanahan and Lynch have done, once you throw out the first year with a pathetic roster and the two seasons that were derailed by catastrophic injury (Jimmy Garoppolo in 2018, Nick Bosa and Garoppolo in 2020): They are 48-19 in the regular season, have advanced to the NFC Championship Game four times, are 8-0 in the wild card and divisional playoff rounds and have played in two Super Bowls.

Preseason rhetoric aside, no team goes into the season convinced its going to win the Super Bowl. It’s a brutal 17-week marathon. Teams play for a chance at a championship, then lay it on the line. A team is built to get to the precipice. Then it’s up to luck, skill and avoiding Patrick Mahomes if you want to win it.

So in the final year of Brock Purdy’s bargain phase before he irreversibly alters the 49ers’ salary cap structure with an extension befitting his new place in the pecking order of NFL quarterbacks, expect them to go about their business as they have the last two years.

They can bring back Brandon Aiyuk on an extension at more than $20 million per year on a contract that will drop his cap number below his scheduled $14 million as a first-round pick on a fifth-year option. Cornerback Deommodore Lenoir and others could be in line for upgrades. Wide receiver Jauan Jennings is a restricted free agent and under team control. Money can be moved and the cap is not really a huge impediment.

The release of Arik Armstead, who reportedly declined a pay cut Sunday after missing 13 regular season games due to injury over the last two seasons, gives the 49ers more financial flexibility.

No sense in gambling on someone else’s players when you know what you’ve got in your own.

The 49ers had a first-day surprise in each of the last two seasons. In 2022, it was cornerback Charvarius Ward (three years, $42 million) and last year it was defensive tackle Javon Hargrave (four years, $84 million). Ward was a second-team All-Pro this season. Hargrave probably wasn’t as much of a force as they hoped but that’s the thing about the first wave of free agency — overpaying is part of the deal.

Tim Brown, who in his playing days was a member of the NFLPA executive board, told me long ago that with the franchise tag, no team loses a player it truly wants to keep. It’s pretty much the truth. That takes pass rushers Brian Burns (Carolina) and Josh Allen (Jacksonville) out of the picture as well as Tampa Bay do-everything safety Antoine Winfield Jr. and Kansas City corner L’Jarius Snead. (Snead, at least, has been given permission to seek a trade, but the Chiefs’ demands are liable to be too steep). Any one of those players would have been a difference-maker on the 49ers’ defense.

So maybe the 49ers make an early strike at Hunter, the Vikings’ edge rusher whose previous deal prohibited the franchise tag. Hunter had 27 of his 87 1/2 career sacks in the last two seasons. He’ll turn 30 during the 2024 season so a multi-year deal is a roll of the dice, although when playing amateur GM it’s pretty appealing to put him on the opposite side of Nick Bosa and turn them both loose.

Or they go the trade route instead and get Joey Bosa from the cap-strapped Chargers. He’d have two years left on his deal at $15 and $17 million, which could be extended to drop the cap figure. It’s hard to know how much Joey would want to reunite with Brandon Staley, his former Chargers head coach who is now a 49ers assistant, given that Nick told reporters Los Angeles needed a culture change after it moved on from Staley.

The 49ers may not be looking hard at Hunter or even consider going double-Bosa. They’re good at hiding their intentions — Ward and Hargrave were big surprises.

They’re also good at building a roster and a contender, whether the 49ers Faithful realize it or not.
