Training is massive in being fast and keeping pace. If he was eating poorer which is GUARANTEED as players didn't know much or care much at all about diet back then. Speed is a major factor in McDavid's game, moreso than maybe anyone ever, so staying in shape would have been important and players didn't have the diet and knowledge of today. Mario smoked fricken cigarettes at intermission back then, and Wayne was eating hot dogs and drinking coke at intermission. Imagine them with todays training and equipment. Connor is better at speed with the puck then anyone ever, but Wayne thought the game way smarter than Connor and didn't need blinding speed to tear other teams apart.
To be fair I was talking more about the goons from the early 80s and 90s which were just that much dirtier. Every team had 2-3 in every game and many of them didn't do much hockey playing, they were basically looking to run people over. Stevens and even Hatcher weren't constantly being dirty all game as most of Stevens hits were considered clean back then. The goons I am talking about are the ones who scored 1-5 goals a season even back then in the high scoring era.
You are way wrong about the people running down today over the past as people, especially here on HF always do the thing of just placing current day players with the same everything of today back then, but don't do so in reverse of putting yesterdays players into today. Imagine how fast Coffey would be with todays skates and training. Imagine Al MacInnis letting rip with todays sticks. If you do one way you have to go the other way too. which is never done by people selling yesterdays players as beer leaguers which has been said of Wayne Gretzky on this site a lot. Imagine Wayne victimizing D with no two line pass like today.
I am not saying the players of previous eras would be bad now. I never made that argument. I agree that Coffey would be great today - he would be Makar/Hughes+. I agree Gretzky would be dominant today.
I am simply saying that Connor is an all-time talent just like those guys you are describing, and would have been just as good in those eras. For soem reaosn, you seem to think that MacInnis/Gretzky/Coffey would destroy today's NHL, but that 1990s McDavid would suddenly be pedestrian because his skating talent would be nullified by *checks notes * hot dogs?
Honestly just kind of ridiculous. Phil Kessel ate hot dogs his entire career and was still one of the fastest players in the NHL. These things matter to some degree, but they do not matter for the absolute best talents that the world has ever seen, which McDavid is. I agree that Gretzky/Lemieux/etc are those talents. I am saying that McDavid is also one of those talents, and it's pure nostalgia to pretend like he isn't.
That is not true. At all. Not one bit. Actual statistics disprove that. McDavid's fastest recorded time is 2/10ths of a second faster than Fedorov's fastest recorded time.
Again, the difference is that McDavid can actually use that speed in today's game without the hooking and holding.
No, it isn't. His actual speed might not be faster, but his ability to play with the puck at that speed is MUCH better than anyone in history, by a massive, massive margin. Fact. Obviously the raw speed isn't the only feature of his game, otherwise Michael Grabner would have been the next Pavel Bure and Dylan Larkin would be just as good as McDavid. Didn't think I had to spell that out.
No, the difference is not about hooking and holding. Again, looks like you don't watch him play at all. Guys are constantly trying to hook and hold him and simply cannot make a connection because he is moving too quickly with the puck.
Just like Gretzky's once-in-a-lifetime ability to think the game 5 steps ahead of everyone else would transcend eras, McDavid's once-in-a-lifetime ability to process the game with the puck at breakneck speeds would also transcend eras.
