Your comment has no relevance to what I said, as I said that competition doesn't impact how good a player actually was, and I don't see what this even has to do with hockey, but...
Chamberlain dominated his peers to a degree that has not been matched by any centre. This includes Russell, whose career nearly completely coincided with Chamberlain's. He also dominated all time greats like West, Robertson, and Baylor whose primes coincided with his own but who played other positions. Discrediting Chamberlain due to his competition would be like someone discrediting Orr because the early 1970s lacked top end defencemen. If you wish to argue that Chamberlain only dominated because of a size advantage (which is an overblown critique) I will remind you of Yao Ming's domination of the NBA over the last decade. I don't feel any further need to discuss basketball in this thread though, so start up the other thread that related to other sports if you wish.
