The Washington Commanders have signed offensive lineman Sam Cosmi to a four-year contract extension worth $74 million, including $45 million guaranteed, securing a key player as they transition to rookie quarterback Jayden Daniels. Cosmi, drafted in the second round of the 2021 NFL Draft, has shown significant improvement after switching from tackle to guard last season, playing all 17 games and allowing only one sack despite the team's struggles with pass protection. General Manager Adam Peters praised Cosmi as a vital part of the team's future, emphasizing his leadership and performance. This contract extension is part of a broader effort to bolster the offensive line as the Commanders aim to enhance their performance this season. Cosmi's previous seasons were marred by injuries, but his 2023 performance ranked him among the NFL's top guards. The Commanders hope this move will help improve their fortunes after several challenging seasons.
