Church was solid but he's replaceable. Of the Cowboys' defensive FAs, they should probably resign Brandon Carr as long as the money isn't too crazy. Despite not really living up to the hype of his original 2012 deal, he quietly held the fort down against a lot of top wideouts...esp this past season. If they can get Claiborne on another "show me" deal, then they should go for it, but nothing more as he isn't reliable to stay on the field. Too bad, as he was having a brilliant season before injury last year. On the flip side, I don't think Brandon Carr has ever missed a game in his career.
'Boys need a good pass rusher though. Gregoy is out all of next season and while Lawrence is making strides, his suspension and subsequent injury last year def set his development back a little.
