Yes because bringing Yao back into the lineup sure does help the already-developed chemistry and up-tempo pace.
Even if Yao healed, the thought of being reactivated would make him overwork like a dumb ox to get back into playing condition. Too risky after what we've been through for the past 4 years.
Yes it's a big conspiracy. The Rockets have decided that they hate talented all-star players and will pay them, and then find every reason they can to keep them from playing. The thoughts on here are really humorous sometimes. Yoyo is right. The good news is that he's recovering well. There was no guarantee how effective he'd be once he did come back. This is some strong evidence that he will be able to be productive and valuable to the team once he's back. That's why it's good news. As far as a conspiracy to keep him from playing, it's all in your heads and backed up by no evidence. There is almost as much evidence to support that Morey is really a space alien, sent to harvest Yao Ming's body.
