Position of need, thy name is defensive tackle. Seriously, right now the Cowboys have Trysten Hill and Tyrone Crawford under contract, and Antwaun Woods is an exclusive rights free agent. Other than that, the cupboard is pretty bare. Crawford may not even fit what the team wants in the middle under new defensive coordinator Mike Nolan, and his contract is an issue right now compared with production.
The Cowboys are going to have to make multiple moves at defensive tackle, and some of that will likely start in free agency.
