He just needs to play more aggressive on both ends. Wouldnt you like to see him getting his fouls while charging to the basket for a vicious dunk? or how about denying an easy lay up at any costs? Both while knocking the opposing players arse on the hardwood floor. Why are Amare, Shaq, and Dwight Howard admired as valuable low post players? One word...aggressiveness.
I have been to plenty of games, and I have never seen Yao play as badly as he did last night. He just looked lost. It was also the first time I have heard the fans boo him.
