"But there are things that I can get a lot better at -- my fundamentals. I've never been asked to shorten or quicken my release and not have a loop in it. The changes I'm making have gone very well and it's becoming more and more natural to me."
I'm concerned with the 'never been asked' part, which reflects poorly on Florida... why do we/they have the QB coach?
A different view on this topic, here, by Smart Football is more redeeming for the QB coach:
The word I had gotten was that Scott Loeffler, Florida’s quarterback coach, had made significant progress with Tim on this but that come gametime, well, a player’s gotta play how he knows how. And Tebow had earned the right to play his way. Yet it is troubling to the lack of progress, and it will hurt him in the draft.
