RunninRaven, I love it. I was going to write just about the same thing. It's not that they think he'll be able to be better then Shaq. It's no one in the NBA currently is able to really compete with Shaq on a constant basis therefore they have to find someone who might be able to and the possibility of someone who is taller might be one of the few chances.
I also wasn't sure what to think of Ming, but I've recent become more impressed. His post moves are actually really nice. I'm not sure if he'll be able to compete against Shaq but I'm expecting him to come in and show the lower/middle starting centers in the league some stuff. It's gonna take time to bulk up and overpower and height the other good ones, but there's a possibility.
I'm a huge Wagner fan also. I think this will be the best overall draft ever, but if I was to take someone that I don't think would be a bust i'd definetly pick Wagner. I also think J-Will, Butler, Wilcox and some others are future (good picks) but from seeing Wagner progress with just 1 year of college and how smart he is I think he'll be amazing also.
