Chris Leak.
With Tebow gone we adapt to personnel. Cam is a Tebow type. Brantley more of a pure passer.
One of the reasons I respect Meyer is that he does a pretty good job of adapting to talent. See the '06 squad and role that Billy Latsko played. Hell, Meyer put in the fullback spot, and we don't even have one now. But then, we don't have a fullback with his blocking and catching skills, and since we don't have a Leak type passing game, there is no need for the extra fullback to block.
If we don't have a Tebow, we'll morph into some other skill set, but you can be sure that whatever it is the goal will be to put the ball into the hands of his skill players, be they Leak or Percy, or even to install a fullback to protect a Leak.
I don't care what we do style wise, just so long as it gives us the best chance using our best athletes.
