Aaron Donald, Stefon Diggs and 7 Late NFL Moves That Could Swing the Super Bowl Race
GOATIFYThe NFL offseason is supposed to slow down once the draft, the first wave of free agency and roster cutdowns are finished. In 2026, several contenders kept shopping anyway, and a handful of late moves now look capable of changing the shape of the playoff race before Week 1 even begins.
The biggest name is Aaron Donald, whose return to the Los Angeles Rams after two seasons away immediately raised the ceiling of a defense that had already added reigning Defensive Player of the Year Myles Garrett. But Donald is only part of the story. Houston added help on both sides of the ball, Washington gave Jayden Daniels another accomplished target, Seattle took a low-risk swing on Trevon Diggs, Dallas added another decorated pass-rusher and Minnesota brought Harrison Smith back for a 15th season.
None of these moves guarantees a championship. Late additions usually arrive because a roster still has a specific weakness, a veteran waited for the right situation or an injury changed the calculation. What makes this group interesting is how many of the players are entering situations where one useful role could matter in January.
Aaron Donald Turns an Already Loaded Rams Front Into the League's Scariest Experiment
Donald is the only player on this list who did not simply change teams late in the summer. He came back from retirement to rejoin the franchise where he spent his entire career, and that distinction is important. Los Angeles is not asking a veteran to learn a completely new system, city and locker room. The Rams are bringing back one of the defining players in franchise history to a team that already believes it should be playing in the Super Bowl.
The timing makes the move even more dramatic. Los Angeles reached the NFC Championship Game last season, still has reigning MVP Matthew Stafford running the offense and spent heavily to acquire Garrett. Even before Donald returned, the Rams had a front capable of dictating protections. Now opponents could be forced to decide how much attention they can realistically devote to Garrett, Donald and the rest of the defensive line without compromising the rest of their protection plan.
The obvious question is not Donald's résumé but his current workload. He is 35 and has not played a regular-season snap since 2023. The Rams do not need him to take every defensive snap in September. They need him healthy enough to become a problem on high-leverage downs and to grow into a larger role as the season progresses. If he looks even close to his previous level, Los Angeles can create third-down matchups few offenses are equipped to solve.
That is why the move changes expectations. Before Donald returned, the Rams looked like a contender. After his return, anything short of a deep playoff run will feel like a missed opportunity.
Houston's Two Late Additions Attack Two Very Different Problems
The Texans did not enter August looking like a roster with no strengths. Their defense carried them to the divisional round last season and finished among the league's most difficult units to score against. The problem was balance. Houston needed more reliability around C.J. Stroud, especially after Jayden Higgins tore his ACL, and it also saw an opportunity to make an already strong pass rush even deeper.
The trade for Kayshon Boutte addresses the offensive side. Boutte arrives after producing 556 receiving yards and six touchdowns in New England last season. He does not need to replace Nico Collins as the centerpiece of the passing game. The useful version of this move is much simpler: Boutte becomes a dependable outside target who forces defenses to account for more than one receiver and gives Stroud a cleaner answer when opponents tilt coverage toward Collins.
Houston also brought Jadeveon Clowney back to the franchise that drafted him first overall in 2014. Clowney is no longer being asked to carry an entire edge group. That makes the fit unusually attractive. Danielle Hunter and Will Anderson Jr. are already the primary threats, which means Clowney can be used as a third wave rather than a rescue plan.
That distinction matters because Clowney was still productive in Dallas last season, recording 8.5 sacks and 12 tackles for loss. If he can reproduce something close to that production while seeing favorable matchups created by Hunter and Anderson, Houston can keep its best pass-rushers fresher and maintain pressure late in games.
The Texans' championship case still depends on Stroud and the offense becoming more consistent. But Boutte and Clowney are exactly the kind of late additions that can eliminate weak spots without asking a team to change its identity.
Stefon Diggs Gives Jayden Daniels a Second Proven Target in Washington
Washington is trying to rediscover the version of itself that reached the NFC Championship Game during Daniels' rookie season. The 2025 campaign went in the opposite direction, ending 5-12 after injuries and defensive problems dragged the team out of contention. The Commanders responded with defensive additions, but the August signing of Diggs may be the move with the clearest effect on Daniels.
Terry McLaurin remains the No. 1 receiver. What Washington lacked during Daniels' breakthrough year was another wideout who could consistently punish defenses for leaning toward McLaurin. Diggs gives the offense a veteran route-runner who has handled high-volume roles and is coming off another 1,000-yard season.
There are reasonable age and durability questions. Diggs is 32 and still carries the history of the ACL injury he suffered in 2024. Yet he is now another year removed from that surgery, and Washington does not need him to be the only engine of the passing game. The ideal role is to make coverage decisions harder, help Daniels on third down and give the offense a second receiver capable of winning against single coverage.
If the Commanders' defense improves enough to keep games manageable, the addition of Diggs could help an offense that already has a quarterback capable of changing a season. Washington is not entering Week 1 with the same consensus contender status as the Rams, but it does have a recent blueprint for making a surprising run.
Trevon Diggs Is a Low-Risk Upside Bet for the Defending Champions
Seattle is in a different position from the teams chasing it. The Seahawks are the defending Super Bowl champions, so they do not need one late addition to rescue the roster. They do, however, have turnover in the secondary after losing Riq Woolen and Coby Bryant, and that created space for an inexpensive upside play.
Diggs joined Seattle in August but did not make the initial 53-man roster. Instead, the Seahawks kept him on the practice squad while he continues to build back up. That arrangement lowers the pressure. Seattle can evaluate whether his movement and confidence are returning without handing him an immediate starting role.
Before his 2023 ACL tear, Diggs was one of the league's most aggressive ballhawks. His post-injury play has been less consistent, but an interception in the preseason offered a reminder of the trait that made him dangerous in Dallas. If even part of that playmaking returns, Seattle can add experienced corner depth during a season in which every opponent will be measuring itself against the champion.
This is not a move that changes the Seahawks' championship probability by itself. It is the kind of depth gamble strong teams can afford to take because the downside is limited and the upside could matter in a playoff matchup.
Von Miller Gives Dallas Another Reason to Believe the Defense Can Finally Hold Up
Dallas did not need another reminder of what went wrong in 2025. The offense was explosive enough to keep the Cowboys relevant, but the defense was historically poor and made sustained contention almost impossible. The front office spent the offseason attacking that side of the roster, and the August 16 signing of Miller added both pass-rush production and championship experience.
Miller is not arriving as the player who once won a Super Bowl MVP award, but he showed last season in Washington that he can still affect quarterbacks. He finished 2025 with nine sacks, six tackles for loss and 19 pressures. For Dallas, those numbers do not need to be repeated exactly for the move to work. The larger goal is to make the pass rush deeper and give defensive coaches another veteran option on obvious passing downs.
The Cowboys have already added Quinnen Williams, Jalen Thompson, Rashan Gary, Cobie Durant, Caleb Downs and Malachi Lawrence across a series of moves dating back to last year's trade deadline. Miller joins a defense that has been rebuilt rather than lightly patched.
That creates one of the more important questions of the opening month: how much improvement is enough? Dallas may not need an elite defense if the offense continues producing at a high level. Moving from disastrous to average could be enough to change close games and make the Cowboys a legitimate postseason problem. Miller's role is to help that transformation become real when opposing quarterbacks have to throw.
Harrison Smith Returns to Stabilize a Vikings Team Betting on a Quarterback Reset
Smith's return is less flashy than Donald's, but it may be just as straightforward in terms of roster fit. Minnesota released the veteran safety with a post-June 1 designation, left the door open to another agreement and eventually brought him back after he spent most of the offseason considering his future.
The 37-year-old remains useful. He appeared in 15 games last season and finished with 54 tackles, a sack, two interceptions and a forced fumble. The Vikings are not asking him to solve their offensive uncertainty. They are asking a longtime defensive leader to make sure the back end remains organized while the team tries to solve a much bigger question at quarterback.
Minnesota won 14 games in 2024 and nine last season. The difference between those teams was tied heavily to quarterback stability. With Kyler Murray now getting a chance to reset his career in Minnesota, the Vikings can reasonably believe the roster is closer to the 2024 version than the record from last year suggests.
Smith helps because veteran safeties can affect more than the box score. Communication, disguise, positioning and understanding how opponents attack specific coverages become especially valuable in late-game situations. Minnesota does not need him to play like he is 27. It needs him to keep mistakes down and make the defense dependable enough to support whatever improvement Murray can create on offense.
Which Late Addition Could Matter Most in the Super Bowl Race?
Donald has the clearest path to changing the championship picture because the Rams were already near the top of the NFC and his ceiling remains unique. The combination of Donald and Garrett can alter protection schemes before the ball is snapped, and that kind of pressure travels well in the playoffs.
Houston may have made the smartest pair of moves. Boutte addresses a specific injury-created weakness on offense, while Clowney strengthens a defense that was already good enough to carry games. Neither player needs to become a superstar for the Texans to improve.
Diggs may have the biggest individual effect on a quarterback. Daniels has already shown that he can take Washington deep into January when the rest of the roster cooperates, and adding a veteran receiver opposite McLaurin gives him a more complete set of answers. Miller has a similar complementary role in Dallas, where the offense does not need much help if the defense can simply stop giving away games.
Trevon Diggs and Smith are different kinds of bets. Seattle can be patient with Diggs because its roster is already strong, while Minnesota knows exactly what Smith provides after more than a decade together.
The broader lesson is that contenders do not have to make their last important move in March or April. By late summer, needs become clearer, veterans become more willing to accept defined roles and injuries create new openings. The best teams keep enough flexibility to act when one of those opportunities appears.
Week 1 will not decide which of these signings was best. Some players will need time to ramp up, some roles will change once injuries hit, and a few may end up mattering far less than expected. But if the 2026 postseason comes down to a third-down sack, a contested catch, a takeaway or one veteran correctly diagnosing a late-game formation, one of these August and September moves could suddenly look like the decision that changed an entire season.
