2 things have to happen before that: Yao reduces his fouls greatly. Yao reduces his turn-over, espeically the easy catch during P-R with tmac. Both are easy to say on the paper, but extremely difficult for Yao... especially if new trend of the league is Run and Gun.
They only thing that needs to happen is to get a tall, athletic guard who can pentrate and hit a jumper to shore up the perimeter and alleviate the pressure on T-mac and a quick power forward that isn't 40 some years old and can chip in 13 points/8rebs a game. Yeah, Yao could be better, but let's face it, there are bigger problems and easier solutions right now then to worry too much about Yao.
