You cant blame a coach for bringing in those types of players unless they're character issues are blantantly obvious. The reason the Cowboys passed on Randy Moss when he was drafted is because he was questionable. It might of been a good move since he is rather mouthy but man is he awesome! You mention some of the awfull players on the Cowboys but what about the ones that had class like Emmit, Troy and Darren Woodson. They were just overshadowed by the other punks.
As for Jimmy, I think it would of been awesome of the Texans picked him up as they're coach. But I like Dom Capers and think he will lead the Texans to sucess down the road. Ya talk about Jimmy being a talent evaluator but look at the future stars that Dom Capers had already picked up.
