Frazier also cited rule changes designed to limit Chamberlain, who famously dumped 100 points on the Knicks. “There were only two players they ever changed the rules for in pro basketball – George Mikan, and Wilt Chamberlain — widening the lane for them,’’ Frazier said. “The two guys they had to neutralize by changing some aspect of the game. If not for Chamberlain, nobody would’ve heard of any of us. I don’t know if there would’ve been an NBA. If not for Wilt and Bill Russell. I don’t know if the NBA would’ve made it. “I would find it hard to say Mike. Mike is right there with those guys, but if I had to pick, it would be Chamberlain.’’
