There is a reason that Kerry Collins has been in the NFL for 14 years, and that is because he is an excellent backup. Sure he had some moments early in his career that were pretty good, but most of his time in the League has been holding a clipboard. He has done well this season with the Titans, but I'll put that on Tennessee being well coached, having an excellent defense, and a great running game. I think most quarterbacks could thrive with what Tennessee has around him, but I'm not sold on Collins doing very well on some other teams.
