I found this interesting. It has little to do with on court performance it seems and more to do with the teams value, but it does take in both at least to some extent. I really like Mr. Alexander. I think he's a good person that works hard. We don't agree on our passions (his PETA) mine (eating glorious meat), but he's been good for the Rockets. He's allowed big trades and hired people he trusts and let's then run the team.
That said, I think he gets a lot of credit for convincing the Chinese to allow Yao to play for the Rockets, but getting that chance was all luck. The value of the team could be attributed more to that luck than one man.
