His screen setting, passing, smart cuts, and offense rebounding make up for his otherwise total lack of offensive skills. And on D, he's a great on-man defender, a spectacular help defender, one of the best rebounders, and he does it all while rarely fouling. So yeah, he won't be replaced anytime soon. And these things are so core to winning basketball that we might end up with fool's gold with our next high priced center. Somebody like Amare who puts up great offensive stats, but who doesn't do all the Ben Wallace things that everyone took for granted.
