I'm not talking just about his turnovers. I think he's often too slow to make the right pass. He's made progress in the last few weeks, though.
Actually for the last couple of weeks Yao's been excellent in some games delivering the ball out of the double team--the TNT announcers commented on it in some of the nationally televised games. He's struggled when he's held onto the ball for too long and looked to score. As long as Yao and the rest of the team can keep the ball moving they'll be okay. There's been a couple of games this season where the first unit, with Yao, really kept the ball moving and worked the offense. If they can play to that level consistently the Rockets will be scary.
