The man had great talent. Lot of people have made mention of his injuries.... and how it relates to his playing style. I agree... his brashness CAN lead to injury. But that has nothing to do with his talent level coming into the NFL.
I haven't followed him so I cannot say to what degree his injuries have limited his abilities.... BUT, he's in the NFL... obviously coaches think he can perform. With as much talent as I believe he possessed I have to think he can still play at a high level. Whether he can come in this late and make that work I don't know.... it will be interesting.
