Seriously though, in analysis, before he hurt his back, Gretzky was the most dominant performer of any athlete in any sport versus the standard "starter" of any era in history besides Babe Ruth. The comparison that was illuminating was Jordan, who would have needed to average OVER 100/PPG to match his pre-injury period (even ignoring the assists, lol). And in truth, he was the greatest hockey player in the league after the injury (Larry Bird wishes he could say the same.)
The dude's fucking Assists ALONE are still the highest point total in NHL history, more than 40 beyond Jagr's total (2nd place all-time).
Across sports, that looks like ~1,000 Home Runs, ~55,000 points in Basketball, and ~100,000 yards passing in the NFL. Whole career, even including the injuries years, that bastard was just under 2 points PER GAME. The guy had four 200 POINT SEASONS. He reached 1,000 points in less than 450 games, and 500 goals in ~550 games. He won the leagues equivalent of the MVP 9x times, as much as Bobby Orr, Maurice Richard, Guy Lafleur, Mario Lemieux, Mike Bossy and Brett Hull combined! Dude holds or shares over 60 NHL records. To call him just the NHL's greatest player is kinda absurd ... he is AT THE TOP of the greatest competitors in their chosen arena of any field.
Beyond that, he was THE guy that changed the ideal player model from the roughneck to the finesse artist. He was 160 lbs. in an era when the league encouraged kicking ass! He finished one season at 183 points, when 2nd place was 108 ... if your not a hockey fan, you won't understand this, but if you are ... HOLY SHIT! 70%?
Anyone who pretends anyone on earth was as dominant as The Great One is definitely under 40. It's not even close.
