At all?!
Human beings change all the time. Even you yourself change throughout your life. Or maybe you don't?
Even if we restrict those changes to height, players have grown since the early nineties:
There goes your "at all".
The simple fact that today's players are on average better skaters than players thirty years ago which is further enhanced by newer equipment underscores that... arguing people who have assumed the stance of lasting denial/blindness by choice borders on insane.
The today's game is visibly faster than NHL ten years ago, let alone three decades ago.
To my eye, kind of similar to your chart there, the game has leveled out around 1995.
Maybe it’s my eye, but
I see a distinct change throughout the 80s. By the late 80s it is looking fairly close to the speed of today, but it’s sloppier (much of this I attribute to goalie pads... the fear of a shot from anywhere forces man on man coverage instead of defensive boxes) and more free.
I just watched Canadian Cup 81 Final. Looks bad to me. Gretzky is trying to play east-west, Dionne and Lafleur having none of it.
The seventies is terrible.
50s and 60s looks better than the 70s - same style but less rubes.
The game style since 1972 has been an ongoing amalgamated marriage of Canadian and Russian hockey.
When money comes into a sport it draws more and fiercer competition. The 90s paid far more than the 80s. I attribute this to Gretzky going to LA, and the Americanization of what was a hick sport in many ways previously.
The wall came down and allowed all players to play
Sundin went first overall
This all happened in a very short period of time, and the message was,
“Hey. If you are good at hockey, and born anywhere in the world, you can be rich! Forget soccer or school, pour yourselves into hockey.”
Pretending that this doesn’t alter the talent pool would be like saying the West Coast would have developed as quickly if Gold wasn’t considered valuable.
But people themselves haven’t changed as much as you think. It’s as silly as thinking that there weren’t tough, big, mean people born in Sweden or Russia simply because their hockey players didn’t play that way. That’s not what their hockey was. Our mean
had hockey as an avenue, their mean
go into crime, or boxing if Russian. Sweden had no combative sports at all until fairly recently.
The reason players are bigger is due to to more training, and more of a worldwide talent pool. It doesn’t reflect on humans. You just get to pick from a bigger litter.
Olympic lifting is not important to many Americans. Hence, they suck at lifting in comparison to Iranians and Bulgarians and Chinese, who DO care. But, when the Soviets cared in the 70s and 80s, and a man could go from another number in the commie computer to a well-off national hero..... well, still today nobody has put more over their head than Taranenko did in 87, and he was not head and shoulders above, in fact he was arguably not even better than Piserenko and another who’s name eludes me... Kurlevich, perhaps.
Money is all, and whenever one gets to the peak of human perfection the gaps between the best and the next best will be minimal. There won’t be Orr or Gretzky unless this sport collapses and goes back to a smaller pool and guys working side jobs. McDavid is ridiculous and could potentially never win another Ross. I think he will, if I had to bet, of course, but he won’t run the next best group over ever, imo.
Add to that that the style of play truly developed and ya, it was bush league.
You can even see it in how long stars remained relevant. Th 06 guys were just fine into their late thirties. The game never developed past them. The 70s guys were outmatched by the 80s youngsters, the game passed them by, but that crop of fellas from the 80s and early 90s played until they didn’t feel like it, or until injury.
So, why do I pick 1995ish when it is clear that many 80s players were still stars into the 90s and even early 2000s? It’s the gaps. Those top 80s guys WERE playing today’s level of hockey, but they look like Gods because much of the league was not.
Money, size, scoring levels and eye test play level has all been more or less great since the mid 90s, with some alterations in rules and style of play resulting from those rules.
