The Dallas Cowboys have put themselves in some trouble with the salary cap, but they can and will make a few cuts to generate cap space in 2014.
Roster decisions aren't as easy as "this player is a starter so we should keep him" or "that player isn't performing up to par so we need to cut him." Teams need to consider value, which is how a player's anticipated future production compares to his contract.
The Cowboys have signed some pretty poor contracts in the recent past (Jeremiah Ratliff, Marion Barber, Jason Witten, Miles Austin and so on), and that has put them in a position where they don't have much salary-cap flexibility.
They'll easily make it under the cap by cutting a few guys and restructuring contracts, but when you sign bad deals, you usually don't have much room to maneuver when it comes to signing high-quality free agents.
Using the contract data at Over the Cap, I've identified five potential salary-cap casualties for Dallas in 2014.
