The Denver Broncos made by far their biggest splash of the free agency period by signing veteran defensive lineman Ty Warren to a two-year contract. Warren has played seven full seasons in the NFL, all with the New England Patriots, but he missed the entire 2010 season due to a hip injury suffered in the preseason. Prior to the injury, Warren had started 88 of 96 games for the Patriots in a six-year span. He recorded 20.5 sacks in his career as a Patriot. Warren played defensive end in New England’s 3-4 defensive scheme, but could fit as a defensive tackle in the Broncos’ more traditional 4-3 alignment. The Broncos gained Warren but lost a veteran on the other side of the line yesterday, as offensive tackle Ryan Harris left the Broncos to sign a one-year deal with the Philadelphia Eagles.
