Tim Tebow...The End.
Just kidding, (sort of). The Gators have Tebow so they don't need anything else right? Well, regardless if they need it, they have it. They are the most experienced National Champion in a long time, and even though no team has repeated as BCS Champions, the Gators are simply built for it.
Urban Meyer is a great coach, but the Gators need to overcome his desire to put pressure on them when it isn't needed. (Posting the comments of a coach that hasn't coached a college game yet from a 5-7 team all over your complex doesn't exactly send the message that "we are the champs, who are you".) Of course, he overreacted to the Georgia touchdown party two years ago too, and that turned out okay for the Gators.
If they do make it to Atlanta and have to face Alabama again, look out. Saban usually isn't fooled twice.
