You can't teach 6-6, 270 pounds. Clarke isn't as polished as some other defensive end prospects in this draft, but who better to work with him than Marinelli? Clarke finished his senior season with 17 tackles for a loss and six sacks.

Scott Crichton, DE, Oregon State.
Crichton is not as athletic as Ealy or Hageman but he still finds ways to get the job done. In three seasons at Oregon State, Crichton recorded 22.5 sacks and 51 tackles for loss.

Will Sutton, DT, Arizona State.
Sutton gained 40 pounds between his junior and senior year and his production dropped off, however, he still earned Pac-12 Defensive Player of the Year honors. He was down to 303 at the scouting combine and said his goal was to get to 290-295.

Demarcus Lawrence, DE, Boise State.
The Cowboys would probably be thrilled to land Lawrence in the second round. He's an athletic pass rusher who recorded 20 sacks over the last two seasons. Lawrence could be the right defensive end the Cowboys are looking for to replace DeMarcus Ware.

Ra'Shede Hageman, DT, Minnesota.
Another big, athletic pass rusher. Hageman is 6-6, 310 pounds. He's a basketball player with the size to play on the interior of the defensive line. He had 13 tackles for loss during his senior year.

Dominique Easley, DT, Florida.
If it wasn't for two ACL injuries in three years, Easley would probably be a lock for the first round. He's a very productive player when healthy, but are the knee problems behind him?

Kony Ealy, DE, Missouri.
An extremely athletic edge rusher that stands 6-4, 273 pounds. He is far from a finished product. But if Ealy gets in the right system, he could be a Pro Bowl caliber player.

Timmy Jernigan, DT, Florida State.
Jernigan is considered to be a one-technique tackle, a position the Cowboys probably don't value enough to spend a first round pick on. That's what it will probably take to land the FSU standout. It's unlikely that Jernigan will still be around for the Cowboys when they pick in the second round.

Anthony Barr, DE, UCLA.
He doesn't have much experience as a defensive player. Barr signed with UCLA as a running back but moved to 3-4 outside linebacker when Jim Mora became head coach in 2012. The move is about to make Barr a lot of money. He recorded 23.5 sacks over the last two seasons. Marinelli views Barr as a defensive end in the Tampa-2 system.

Aaron Donald, DT, Pittsburgh.
Donald is an ideal fit for Rod Marinelli's system. Although the Cowboys already have Henry Melton to play the three-technique tackle spot, they'd gladly add Donald to the rotation. Of the 10 players mentioned here, Donald is the most likely to be gone when the Cowboys pick at No. 16. Follow Jon Machota on Twitter: @jonmachota
