As a Wisconsinite, I have seen this guy develop as a college player. He has many guard-like skills because he went from 6'2" to 6'8" between his sophomore and junior years of HS. His game has really developed offensively in all areas, though he is more of a face-up player than back to the basket. Bo Ryan knows what he is doing, so this kid will not make fundamental mistakes.
My real questions for him on the pro level are his ability to defend. Wisconsin was not as solid defensively this season as years past, due mostly to a lack of inside presence defensively. This should tell you something about his presence around the basket.
He evidently played well against the pros last summer when the FIBA team played against college players. I don't see this guy as a starter on good teams, but could definitely help off the bench. He certainly will know his role every season, so we wouldn't have to hear that anymore.
