I don't think the Asian Games will wear Yao out. The games are only 40 minutes each and most of the games are vs. scrub team and Yao will probably play 20 minutes.
No offense are you a Chicago fan? Rockets are not going to trade Yao for any player in the world, not Curry, not even Lebron James.
I do not want to see it happen as well. But Rox better do something with regard to Yao's NT obligations. If Yao has to do this thing year after year, you will expect a breakdown of Yao.
