As the 2025 NFL regular season approaches its conclusion, the impact of free-agent acquisitions has become increasingly apparent. With just a few playoff spots still up for grabs, standout signings have propelled teams to unexpected heights. The following highlights the most significant free-agent moves from the offseason, showcasing how these players have transformed their new teams.
Sam Darnold Shines with Seattle Seahawks
When the Seattle Seahawks traded Geno Smith to the Las Vegas Raiders in March, many questioned the team’s strategy. Signing Sam Darnold proved to be a pivotal decision. His performance has transformed the Seahawks into serious Super Bowl contenders, with a current record of 12-3. Darnold ranks fifth among qualified quarterbacks with an 81.0 PFF passing grade and boasts an impressive 2.16 Wins Above Replacement. His ability to build rapport with rookie receiver Jaxon Smith-Njigba and lead clutch comebacks has been crucial for Seattle’s success.
Davante Adams and the Los Angeles Rams
The Los Angeles Rams made headlines this offseason by extending quarterback Matthew Stafford and signing Davante Adams, who has been instrumental in their offensive resurgence. Now at 33 years old, Adams has returned to form, achieving an 84.1 PFF receiving grade—his highest since 2022. His contributions have helped the Rams secure a top position in offensive efficiency, marking them as a frontrunner for the Super Bowl.
New England’s Stefon Diggs has also made headlines with his significant impact on the Patriots. After a dismal 4-13 record last season, the team has surged to 12-3 in 2025. Diggs, who signed for $65 million, has been a critical asset for rookie quarterback Drake Maye, achieving an 84.2 PFF receiving grade and leading the team in first downs.
Defensive Standouts and Key Contributions
On the defensive side, Joey Bosa‘s signing with the Buffalo Bills has injected new life into their playoff aspirations. Bosa possesses an 88.9 PFF pass-rushing grade, ranking sixth among edge defenders. His ability to pressure opposing quarterbacks has been essential for a defense that aims to compete in the crowded AFC playoff picture.
The Chicago Bears have also seen a transformation, largely due to Drew Dalman‘s addition as center. His 78.4 overall PFF grade places him among the top centers in the league, significantly bolstering the Bears’ offensive line, which ranks fourth in overall grading.
Other notable acquisitions include Mac Jones of the San Francisco 49ers, who stepped up as a backup quarterback during Brock Purdy’s injury. Jones posted a 76.0 PFF passing grade across his eight starts, contributing to the 49ers’ postseason berth.
Meanwhile, Poona Ford‘s signing has solidified the Rams’ defensive line, with an 89.5 overall PFF grade, making him a key player in their run defense. Similarly, the Patriots’ Robert Spillane has excelled in his new role, demonstrating his capabilities as a run-defending linebacker.
As the 2025 season approaches its climax, these free-agent signings are instrumental in shaping the playoff landscape. With teams like the Rams and Patriots benefitting from strategic acquisitions, it is clear that the offseason moves have had a lasting impact on the league. The coming weeks will determine which of these teams can convert their successes into postseason triumphs.
