Yao need to provide weak side help. Get some cheap blocks like AK. Jump straight up and spike those weak floaters in the lane.
Like Van Gundy said, turnover disrupt the chance to play efficient basketball. If Yao didn't have that crucial period in the 4th where he has missed shot, 2 violations, and McGrady missing shot, we would be in the game. Yao can shoot bad, but he needs to stop with the turnover. A missed shot stil gives the team chance for offensive rebound. Turnover doesn't. Yao is 7'6". He's getting pushed around by OKur.
