LOL. Your standards are kind of harsh. The guy averaged what? 22 RB for his entire career? And averaged something like 42 minutes per game for his career? Find me a player today who could just play the minutes he did.
You're right, though. His FG% was not very good, and he shot FT's like Andre Drummond. But the guy was a ing beast on the floor. All he did was make his teams winners. It's hard to overrate that.
Wilt was way ahead of his time. In the Golden Age of big men (DRob, Shaq, Duncan, Hakeem, Mourning, etc.) he would have fit right in, but I'm not sure he would have been the giant he was when he played. Not debating how incredible he was, just saying that he was pretty much alone.
