I've said this here a few times last year, AB shies away from contact. That was the main reason why he wasn't moved to D last year. True story. The kid is a fluid talent on O, just needs to get focused on his technique and mindset.
Also, he's a pretty talented receiver. If he continues working on securing the ball before looking for his next move, we will have a stud next year. He's already impressive as hell given the circumstances.
He will never play D at SU, ever. That's the truth Mike. Wish I had a better answer for ya!!!
