Shaq's game was built on size and strength, Wilt had skill. Remember Wilt had a post game, a bankshot ala Duncan and even played guard with the Trotters. I think he'd be a 35-17 kind of guy. But hey I think Russell could put up 15-15 with 5blockas and assists too.
Shaq in his 99/2000 dominant year had Zo and Zeke, an past him prime Hakeem, a past his prime Ewing and a past his prime Robinson. Lots of Gieghers, Roberts, Ervin Johnsons, Shawn Bradley's out there.
