He was already a rich man's Frye in his freshman season. As I mentioned, in preparation to play center he added a fair amount of muscle going into the season but it was clear he had the frame to add even more. I'm not sure but I think he slimmed down a bit during the season though as he was needed to play the 4 mostly along with some time at the 3.
He wasn't bulky at any point but he was still a very well built young man, not skinny at all. IMO, teams passed on him not because of anything he did or didn't do in college but primarily because so often in the past this type of player (white Euro, finesse, outside shooter) has been a disappointment. It was easy to assume he might follow in their footsteps.
