He plays too hard. A good fault to have but he burns himself out by the end of a season. He's one of the greatest edge rushers for the Cowboys I have even watched.
I pick up his 5th year option and then give him the non-exclusive tag, IMO this will give us his best 5 years of his career on his rookie deal and will probably net us two 1st round picks in compensation.
After the early 90's when FA started, it's all about your team and players normally do not stay with the same team throughout their career anymore. Since it's a business now, treat it so and make the un-emotional choices.
