Then there are the intangibles, which I suppose you could subsume under coaching. Thanks to Meyer, Florida has a toughness and self-confidence that spans the full quarters--something they haven't had for a long, long while.
UF must do a good job on kickoff/punt coverage, it is critical to pin OSU back and make them work a long way down the field.
Leak doesn't have to be spectacular, but he needs to make enough plays without making any boneheaded interceptions. This is key for Florida. Leak is capable, but he needs to play the game of his life. I don't think Tebow is going to be a huge factor, other than in converting 3rd and short opportunities.
I expect OSU to get a bunch of yards, they will probably get at least 400 yards on the Gator "D". Bend but not break, don't give up the big play, and clamp down in the red zone to force FGs.
Harvin is the one guy that OSU will fear, UF must utilize him to their fullest, if anything use him as a decoy to open up the running game and open up opportunities for the other receivers. If Florida is to win, Percy Harvin is going to have to become a household name by the end of the night.
And foremost, Florida cannot get down by more than one score early, or it will be a long night for the Gator Nation.
