And someone tells me "once is enough", when questions such as this protrude out. Well, hate to sound annoying. But, the reason you'd want to trade the "best" player on the team, would be, because it could get us a BETTER OVERALL player from another team. Tis in the sig.
In terms of rebounding and shotblocking and defense, Catod oes enough. Ben Wallace is great, but his lack of offense wouldn't make Yao's like any easier. I'd arther go for Chandler, who is as good a rebounder and shotblocker, and hope he develops a very simple offensive game (15-footer).
I can give you free **** and *** just come into Houston Dolls at night and ask for Kevin. I hope that helps.
