Listed at 6-foot-3 and 308 pounds, Dareus is a versatile lineman who proved capable of pressuring the quarterback as well as stopping the run. Dareus was the defensive MVP in helping the Crimson Tide defeat Texas in the 2010 national championship game.
He joins a Bills defense that took much of the blame for the team's 4-12 finish. The unit particularly struggled against the run. Buffalo allowed 200 yards rushing eight times last year, and 2,714 overall — the second-highest total in team history.
