It is a well-rounded group, with a strong class of pass-rushers off the edge, interior penetrators and run-stuffing nose tackles who will plug the middle of the line. USC defensive tackle Leonard Williams rates as the top player on some draft boards, and defensive ends Shane Ray, Randy Gregory and Bud Dupree should be top-20 picks.
The Dallas Cowboys’ biggest off-season move came in the signing of defensive end Greg Hardy. Dallas had only 28 sacks last season, with Jeremy Mincey leading the team with six. DeMarcus Lawrence, who missed nine games with a broken foot, will get first nod at earning a starting job on the other side. Mincey, Ben Gardner, who spent his rookie season on injured reserve, and Jack Crawford will compete for playing time in the team’s rotation. The Cowboys moved Tyrone Crawford from defensive end to the three-technique last season and were happy with the results. He had three sacks and was solid. Nick Hayden re-signed to play the nose, though the Cowboys have hopes Josh Brent got the rust off with two games last season after missing the 2013 season. Terrell McClain also should see playing time in the defensive tackle rotation. The Cowboys might pass on a defensive tackle, but they will take a defensive end or two.
