He is not that weak anymore, and probably somewhere between 240-250. His height makes him a little easier to back down with a higher center of gravity, but also is an invaluable asset for getting off a shot or grabbing a rebound.
I still think he isnt good enough to be a good nba player. He can be a good backup player but he would be a very good player in Europe instead. If i were him, i would definitely stay in Europe because i dont see he has much chance to be a starter in any team in nba.
