I just don't see it as being that big of a deal. ACL tear two years ago and a off-season shoulder cleanup surgery that he played through without it hurting his performance. Neither of those are chronic problems or indicative of nagging future injuries.
This isn't a Davenport, Turner or even Penning situation where they played at small schools and maybe the jump in competition could be a factor in injuries either. He was playing against some future pros.
