Who is "The Greatest One"?

I think of the three the most talented was Lemieux, however that doesn't mean he is the best player. I would put Orr as #1 because he is the only defenseman to win the art ross, and he played in the same era as Guy Lafleur and Phil Esposito. Gretzky would be second in my mind. He had the best vision on the ice of ANYBODY who has played in the nhl, and was the best at capitalizing on all the talent he had and the talent around him. I think Lemieux is the most talented player to ever play, but he wasn't able to get as much out of the players around him like Gretzky
