Tim Heitman/USA TODAY SportsTyrone Crawford could end up as the Cowboys' starting strong side defensive end if Anthony Spencer does not return.

Tyrone Crawford

Position: Defensive end

How acquired: Third round (No. 81 overall), Boise State

What he did: Crawford developed nicely as the season wore on. He was active for every game but did not record a start. He finished with 33 tackles (18 solo) and five quarterback pressures. He was not able to get to the quarterback as much, but the Cowboys liked his build for the 3-4 and position flexibility at 6-4, 285 pounds. He also saw work on special teams on the kick return unit. The coaches lauded his work ethic and saw a player become more technically sound as the year went on,

Where he fits in the future: It's possible he could be a starting strong side defensive end, especially if Anthony Spencer is not re-signed as a free agent. He has the ability to hold up against the run and also get up the field to provide some pass rush push. Monte Kiffin's strong-side ends during his time in Tampa Bay, like a Greg Spires, were often underrated and benefited from the attention given to other players up front. Crawford will have to learn the craft as he goes, but he will have a tremendous teacher in new line coach Rod Marinelli. In order to make this scheme switch, the Cowboys are banking on players such as Crawford being able to learn on the fly as they alter their preferences in defensive linemen.
