At UCF, he's going to be facing weaker defenses in the AAC.
If he went to FSU, then he would be facing bigger, stronger, and faster defenses in the ACC. As much improved as the AAC has become over the years, there's still a big talent gap when you consider the average team in that league versus the ACC.
This way, he'll be a lot more relaxed, and be able to go through receiver progressions at a more relaxed pace. I suspect that he'll post decent passing numbers at UCF.
Maybe this will give him a chance to learn on the job, and become the complete quarterback we had hoped he could be at ND. I hope he does.
