I have met several people like you who hate Tim mostly because he is a good kid and it shows them that people can succeed while not cheating, lying, screwing around, drinking, etc. He tweaks their own guilty conscience. However, I am not saying that is why you don't like him.
I hate him first and foremost because he's a Gator. I also think that he's taken the whole "Jesus helped me win" shtick to a new absurd level. I wonder if Jesus helped him taunt the other team and draw all of those Gator Chomp unsportsmanlike penalties.
I guarantee you'd never see Colt McCoy do that. But like Tebow said, I guess that god just loves Florida more than the other teams.
