He's averaging over 22 points in conference and 4 assists. That's around 30 points per game he is accounting for. Not to mention 5 rebounds and 1 steal per game. At over 9 FT attempts per game (12 in the last 5) he is helping to get us in the bonus and creating some foul trouble for the other team as well.
That's a lot he's doing. He's also taking pressure off the other guys allowing them to be more efficient with their looks. I mean the rest of the guys don't have to take on too many bad shots.
