And judging by the reaction around the NFL, plenty of people agree.
But with the 49ers at 6-1 and heading into the second half of the season, I'm more interested in what Buckner can do for this defense than how little Lynch paid to get him.
The 49ers have Super Bowl aspirations, and Buckner gives them another proven player on a defensive line that has dealt with injuries all season. Whether his arrival makes them significantly better against the NFC's strongest opponents will depend on how they use him and what the players around him bring.
The Pass Rush Just Got More Dangerous
San Francisco's 29-20 loss to Atlanta exposed a problem that Buckner could help address immediately.
The 49ers failed to record a sack or even a quarterback hit against Michael Penix Jr. After generating nine sacks over their previous two games against Seattle and Washington, the defensive line couldn't get home against the Falcons.
That kind of inconsistency becomes dangerous when you face quarterbacks who can pick apart a defense with enough time in the pocket.
Buckner has 75.5 career sacks, including four this season, along with eight quarterback hits in seven games with Indianapolis. At 32, he's still producing, and his ability to generate interior pressure gives San Francisco something it hasn't consistently had.
Nick Bosa's anticipated return after the bye makes the addition even more intriguing.
When a defensive tackle can push the pocket from the middle, quarterbacks have fewer opportunities to step up and escape edge pressure. That could benefit Bosa, Mykel Williams, and the other defensive ends, while Buckner could benefit from the attention those players command.
Add Osa Odighizuwa to the interior, and the 49ers have several players who can create problems for opposing offensive lines.
Of course, that group's potential depends on Bosa returning healthy and the defensive line developing the consistency it lacked against Atlanta.
The Run Defense Still Deserves a Closer Look
Here's where I have some reservations about the acquisition.
Buckner's ability to rush the passer is well established, but his run-defense effectiveness has been less convincing this season. He can disrupt plays in the backfield, but that doesn't necessarily make him the interior run defender San Francisco has been missing.
Interestingly, the 49ers' overall rushing statistics have been strong. They've allowed approximately 89 rushing yards per game, ranking among the league's better defenses in that category. Against Atlanta, they held Bijan Robinson to 63 yards on 20 carries.
But the concern is whether San Francisco can maintain that performance against more physical offensive lines, especially when opponents commit to running between the tackles.
Buckner's arrival gives defensive coordinator Raheem Morris another option, and the trade's value may extend beyond his individual production.
With Odighizuwa, Gracen Halton, and other defensive tackles available, Morris can adjust his rotation based on the opponent and the situation. C.J. West's expected return would provide another option.
Buckner doesn't have to handle every interior responsibility. But the 49ers will still need their defensive tackles to hold up against the run, no matter how much pressure they generate on passing downs.
Buckner and Nelson Could Decide a Lot in the NFC West
The timing of this trade makes it even more interesting.
Earlier Tuesday, Seattle acquired eight-time Pro Bowl guard Quenton Nelson from Indianapolis, strengthening an offensive line that was already preparing for another battle with San Francisco.
A few hours later, the 49ers acquired Nelson's longtime teammate from the Colts.
Buckner and Nelson spent years facing each other in practice. They know each other's tendencies, strengths, and techniques, and now they'll be competing on opposite sides of an NFC West rivalry.
Nelson has been exceptional in pass protection this season, reportedly allowing no sacks through 275 pass-blocking snaps. That presents a considerable challenge for Buckner, though it's premature to assume Nelson will neutralize him.
The same applies in reverse. Buckner's arrival doesn't erase the advantage Seattle gained by acquiring one of the NFL's premier guards.
And given Nelson's run-blocking ability, their matchup could test the very area of Buckner's game that raises the most questions.
The Seahawks improved on Tuesday. I believe the 49ers did, too. How those improvements translate when they meet again could significantly influence the NFC West race.
A Bargain With Bigger Expectations
Although Buckner missed time with an ankle injury in 2024 and a neck injury in 2025, he's played all seven games this season and already has four sacks, giving the 49ers reason to be encouraged about what he can contribute.
The 49ers have the bye week to begin integrating him into Morris' defense before returning against Las Vegas on November 8.
Lynch got a proven defensive tackle without giving up a premium draft pick, and Buckner's familiarity with the organization should make his return easier.
I like the trade, and I believe it will improve San Francisco's pass rush. But I still have questions about the defense's ability to control the line of scrimmage against the NFC's strongest teams.
The 49ers have already shown they can stop the run and pressure quarterbacks. Their challenge has been delivering that performance consistently, even when injuries force lineup changes.
Buckner gives them a better chance to do both.
For a fourth-round pick, that's excellent value. Whether it becomes a championship-changing acquisition will depend on what happens on the field over the next several months.
