Safe assumption. If he does come, I'lll be at a loss as to why, but it sure would be good for the program. Think about it objectively - why would someone of his caliber want to limit himself with coaching and practice partners? We can all hope in the face of irrationality.
Yes, Knox is an exceptional talent. However, a responsibility comes with him. He cannot become another top recruit to do better his first year and not progress, or as some like to say, not pan out. Too great a talent to waste. However, his presence would be a significant benefit to the other guys around his weight.
