Claiborne has yet to play a full preseason
Honestly... we would've been better off keeping Mike Jenkins and not signing Carr. You can't really knock Dallas for drafting Claiborne because he was the number 1 rated Corner in that draft. Every corner that was drafted after him in the first round hasn't done much neither.
The NFL rules make it hard for corners to play physical, plain and simple. Offenses are at a huge advantage, so unless a corner goes to a team with a great pass rush and plays alongside great veterans, its going to be a struggle no matter who you are.
