The Dallas Cowboys head into the 2013 NFL Draft with glaring needs on the offensive line, and many expect them to address those needs.

SB Nation's Matthew Fairburn released his latest mock draft on Monday, where he has the Cowboys taking North Carolina offensive guard Jonathan Cooper 18th overall:

If Chance Warmack is the best guard prospect to come around in years, Jonathan Cooper isn't too far behind. He has picture-perfect technique both when firing out of his stance and when pulling across the line of scrimmage. The Cowboys need all sorts of help on the offensive line. Tony Romo would appreciate a bit of help up front.

Romo isn't getting any younger, and the Cowboys need to keep him upright and improve the defense if they want to keep their contention window open. Either Cooper or Warmack would make perfect sense in this spot.

On the other hand, the Cowboys are transitioning to a more traditional 4-3 with the hiring of Monte Kiffin. With Jay Ratliff's status up in the air, defensive tackles like Sharrif Floyd, Jesse Williams and Sheldon Richardson could all be available here
