If the comparison is Shaq, then there is no comparison. No human being will ever come close to Shaq. Ever. Patrick Ewing (who by the way, also took a lot of jumpers) and David Robinson (ditto) would be soft too if the bar is set to Shaq's level.
Yao Ming is dominant. He is that good. Shaq is the only big man I've seen in my life that doesn't need a jumpshot. Maybe Wilt and Kareem are like that too, but I've never seen them. Every other great centers or 7-foot PF use the jumpers regularly: Ewing, Robinson, Hakeem, Zo, Duncan, KG, etc. I don't get why shooting jumpers mean you're not dominant.
For every jumpshots that Yao takes, he shoot at least three shots from within five feet. I don't get where this Yao as a Brad Miller type jump shooter is coming from. Because he hasn't played that way since he left China.
I just think this Yao is not a dominant center thing is coming from way out of left field. He isn't as dominant as Shaq, but who is. Yes, he need to score to be effective because the team is build around Yao being able to score. It'd be nice to have Hedo and Rashard to carry the scoring load, but the only other 20+ pt scorer on the Rocket is out for the season. So yes, Yao needs to be 24 and 10 to be effective because he is the team's only consistent scorer. Ron Artest isn't a consistent scorer,he only thinks he is.
And while the idea that you either play 100% or don't play sounds good on paper, it isn't practical. Especially for big guys. Shaq took plays off all the time, and to some extend so did Chris Webber. For the amount of punishment that big men take, it's all about pacing yourself so you don't break down come post-season.
