The NFL has seen many college pedigreed pure pocket passers with gaudy stats, flame right out. Tebow has done nothing but win his entire career. A lot of people forget that a number of colleges wouldn't give Kelly a chance to play QB. Even Penn State had him playing LB, not QB. Kelly went to My Yami and the rest is Hall of Fame history.
I would definitely take a shot at Tebow. His leadership abilities would do wonders for this team, which hasn't had a real offensive leader since Kelly and to a much, much lesser degree, Bledsoe.
I think Kelly sees a lot of himself in Tebow and if he thinks Tebow would be a good fit for the Bills, who on this board has the credentials to argue with that?
