Man, he did a damn fine job playing Sully straight up on the low block... picture perfect defense with his arms extended vertically and his legs glued to the floor. He stood his ground, and locked up O ST's bull in the paint, and added 17 of his own (perfect from the line, as well). He times his rebounds very well, and works well on the pick-and-roll. I'd look long and hard at him in the 2nd rd... he could serve as the Wagon's apprentice for the next couple of years. He has legitimate size at 6'10'' 280 lbs, and could be a situational defender off the bench. He's definitely worth a look, as the Rockets are in need of more big bodies with a drop of common sense and a willingness to play D (...J-Chill, fail).
I like his size. He also seems like a hard worker on the court. I'd think that he could make it in the NBA. How good could he be? I have no idea.
If he finds a place it will be as a third defensive pf/center on some team. Josh has become a very hard worker, but his talent is even less than Joey Dorsey. Though to be honest, he may improve more each year... now that he has changed his habits.
