I think a lot of the Kelly recognition is coming from his creativity and innovation. He essentially started the no-huddle offense and had huge success doing it. If Bills win first super bowl, I think top 15 no doubt. Otherwise, tough call...
If he's the best QB in the draft, he'll be a Cleveland Brown in April.
Otherwise unless something major happens, he'll be gone in the top 5. Bills will have to give up the farm for him in a trade up.
