I agree that this is probably what he is going forward. However, even at 80% athleticism, he's still one of the most athletic centers in the league.
On a side note, the progress he has made at the actual game of basketball is wonderful. He may not be able to touch the top of the backboard, but they actually run dribble hand offs with him. I'll take his growing bball IQ at his salary and capabilites any day of the week.
