The Buffalo Bills certainly entered the 2021 season confident in their depth at defensive tackle. They returned a first-round draft pick, two former first-round choices whom they signed as free agents, a beloved third-round draft choice, and a high-motor free-agent signing. The group looked to have some solid depth.
Despite those plans, the Bills struggled at times along the defensive interior. Injuries, inconsistency, and poor gap integrity opened up a big weakness against the run. By the end of the year, the team essentially had two players they could rely on to play in the middle, which is problematic for a team that rotates its linemen as much as Buffalo does.
