Just for the record, I would take Wilt Chamberlain over Bill Russell, too. Winning more championships doesn't necessarily make him a better player. If that was the case, Robert Horry would be considered better than Michael Jordan.
I wouldn't. Russell was a much better defensive player, and just a better all around player. I'm not taking anything away from Chamberlain, mind you, but he had a pretty big height advantage over Russell, and still couldn't outplay him.
