Brantley is the better QB.
The future of UF is Brantley not Newton, even if Newton didnt screw things up for himself.
After watching Newton this past spring in the O&B game, I wasn't very impressed with his performance.
I saw that Brantley had a lot of upside when I watched him play in the high school All-American game, and not only did he show his prowess at QB, he also has a decent leg as far as punting goes as he was on dual-duty in that game. In Coach Meyer's spread offense, his passing abilities are his strongpoint as far as I can see - give him speed and accuracy with a receiving corps and he could be lethal to opposing defenses.
Once Tebow's college days are over, I could see Meyer implementing a two-QB system as we had in 2006, unless Brantley can command our offense as well as Tebow has been able to do for his past two years as a starter.
