I agree and...
I do not understand why we have a guy like DS in the center not playing like a center. I don't think he boxes out well, and I did not see him focus on clearing the ball out to a guard when he did get the defensive board. He would take off dribbling it. That, to my old head, makes no sense. Get the dang ball to a guy who ball handles for a living, and move up the court, get in position.
The other thing that got my goat in the playoffs was his tendency to stop playing the game and wait for a foul whistle. I think he needs to work on playing the game unless he hears the whistle. Drives me nuts.
He can be a lot better...a lot...just my opinion.
