If I'm not mistaken, back when he was being recruited, geography played a crucial role in his decision because his father wasn't in good shape, and he wanted to be close to home..
That was making the rounds in the college recruiting sites and blogs when Pryor was in the short hairs of making his decision. I've discounted it because if that was a big factor, he'd have went to Penn State which if I recall correctly, is where his Dad wanted him to go.
As far as his propsects are concerned, he may be hugely talented in terms of athleticism but those skills are not translating into him being an effective college QB. At this point, although early, can you really project him as an NFL caliber starting QB?
The emergence of mid major college type QB's who demonstated the pro-style attributes needed to succeed in the NFL like Flacco and Ben should be more than enough evidence to demonstrate to NFL scouts that they need to stop drafting athletes who happen to play the QB position with the intent of coaching them up after they are drafted.
