Gretzky does praise a lot of players. But he is a huge fan of the game. I think this praise is pretty accurate.
Gretzky actually does not praise a player as the best every week though. I mean over the last decade plus I can recognize the handful of players he praised too much with hyperbole.
I think Gretzky praise has got massively underrated at this point.
Anyway, regardless of Gretzky's comments... I hope McDavid is truly a talent above almost all others. I became a hockey fan in the middle of Gretzky's prime in Edmonton. There really is no one close to Mario or Gretzky. Tons of great players I have seen. But Lindros, Messier, Jagr, Crosby, Ovechkin... none of them approached 99 or 66. I hope McDavid is really that next guy. That he gets 120/130/140 points all the time and just is in another class of player and every game he has a half dozen WOW how is that possible moments.
