The part in bold is a a ridiculous reach. Chamberlain was a complete basketball player. You can argue that he was selfish, and their are many stories verifying that opinion, but Chamberlain could do everything and anything on a basketball court. He is the Babe Ruth of basketball and really only two players are comparable to him in the history of the NBA (Jordan & Abdul-Jabbar), IMO. People complain that he didn't win enough or didn't put winning over putting up statistics, but Russell almost always played with better teammates. It isn't a coincidence that Wilt played on two of the greatest NBA championships teams ever in Philadelphia and Los Angeles.
I respect Bill Simmons opinion on the NBA, but he's still a life-long Celtics fan. Which leads me to believe that he'd never put a Laker as no. 1 on any list.
