Bad character out for self etc. people made a big deal when Garrett first took over about him changing the culture with Garrett guys or something. Anyways that has basically failed and been forgotten, but I still doubt we would claim him if given the opportunity. Personally I like his tenacity and think a bit of a bad attitude may be a good thing for the Cowboys.
The only thing that makes him a player with an attitude is cuz the Raiders picked him so people labeled him as a tough guy. But Garrett took Dez and he has an attitude. I honestly think it comes down to need and LB is a major need.
