This will always be one of my favorite board arguments that I never get tired of, it's my personal on campus football stadium as it were, because in my mind Pryor was a no doubt decade long NBA starter.
I use Dion Waiters and Iman Shumpert as common comps because they were highly rated strong, athletic wings but Pryor was bigger, a better athlete, and a better basketball player than both of them. He had very good court sense, was a good creator, and could defend inside and out. If he focuses on basketball he's a McDonald's All-American and a first rounder in two years.
Instead though, he had the misfortune to grow up in western PA where every player is pushed into football no matter what, even though he really didn't have an obvious position on the next level. He didn't have the arm skills to play quarterback on the NFL level but because Vince Young had just been a thing people drew the obvious comparison there but he also wasn't a great fit at wide receiver either, he was too big and just didn't have the separation ability which is why he crashed out of the league at that position too. He was probably best off bulking up to play defensive end on the professional level but that requires significantly more work than he would have needed on his jumper.
