This. I’m no puckhead, but Gretzky played in the least popular major sport, for a Canadian team, in the western time zone, well before the surges of the 24 sports programming, the internet and social media. The NHL was forced to change the rules of hockey because Gretzky (mostly) and the rest of the Oilers were so dominant on power plays. Gretzky was probably the greatest/most dominant singular player of any team sport in the history of sports. And I don’t even think it’s close. As far as TB being the greatest champion, Bill Russell disagrees. I've been involved in this conversation a couple of times before and the answer is some cricket player.
