Quinton Jefferson returns to the Bills after previously starting four games in 2020. He has had a varied career, spending time with the Raiders and Seahawks before contributing significantly with the Jets last season, where he recorded 34 tackles, 13 quarterback hits, a forced fumble, and a career-high six sacks. Most recently, he was with the Browns but was released after being active in five games. McDermott has been monitoring Jefferson's journey and is looking to leverage his past production to strengthen the team's defensive line.
