The Cowboys have benched 2 of big name starting players, who were early draft picks, CB Morris Claiborne and LB Bruce Carter.
Claiborne's benching was announced yesterday (Oct 2nd), and he has been replaced by CB Orlando Scandrick (4.30-40). Claiborne was the Cowboys 1st round pick (#6) last year, trading up to draft him (the #14 and 45th picks to get the 6th pick). Claiborne was a great CB at LSU, with OK size (5'11", 188), and long arms (33 1/4"), but just average speed (an "official" Combine 4.50-40, "unofficially" 4.47 and 4.54, but a Pro Day 4.37-40), but a pretty poor 1.60-10 yard split. As a rookie in 2012, ProFootballFocus.com ranked him as the 83rd best CB out of 113, and so far this season he's ranked as the 94th best CB out of 101. So far Claiborne is looking like a huge draft bust.
LB Bruce Carter (6' 1/8", 241) was benched this afternoon, replaced by career journeyman Ernie Simms. Carter was the Cowboys 2nd round pick (#40) in 2011, a 1st round talent who dropped because he hadn't recovered from his injury at UNC enough to workout before the draft. He started out last season like a Pro Bowl player as a 3-4 ILB, until he went on IR after the 8th game. This season the Cowboys switched to a 4-3 Tampa 2 defense, moving Carter to 4-3 OLB, but his play isn't up to his past standards (much like the Panthers Jon Beason), with ProFootballFocus.com ranking him as the 4th worst 4-3 OLB.
Before anyone ask, I don't think the Titans would have any trade interest in Claiborne, but maybe Carter, on the chance that he's still recovering from his injury, and that a move back inside at LB might restore his previous high level of play. The Cowboys might have a trade interest in Britt and McCarthy.
