Yeah i know that Usain Bolt can run faster than Gretzky and Mark Henry is stronger than him. But you cannot list someone as dominate as gretzky was in his prime. The closest you can get would be Mike Tyson, GSP, or Silva. No NBA, NFL, MLB, EPL, etc player has ever run away with scoring like that. I am attributing being an athelete in connection to dominating the sport. SO in hindsight, Gretzky is the "greatest" pro athlete of all time. A sports MVP, if you will.
