I think it’s just about media. We have been told since before they entered the league that Sid is better. Even when Ovie was without a doubt better, before Sid hit his peak and before he had really developed much of an all around game, and actually before the Golden Goal (which he was given far too much career credit for, IMO) there was still a narrative based around that one Cup.
People get brainwashed. Simple as that. It’s in politics, it’s everywhere. The media doesn’t have to lie, just report what they want to over and over until it is the truth.
You are 100% right. There is a term for this in politics and marketing - it's called an "illusory truth."
I've said that for years. Coming out of the lockout, the "new NHL" was all about marketing Crosby as the next Gretzky, and they had to make every good play "great" and every great play "legendary" in order to push the narrative. And the hockey media latched on. To your point - an example of this was the "Golden Goal." If Jamie Benn or Joe Thornton scores that goal, it's a "winning goal" but since Crosby scored it, it's the "Golden Goal" and plastered all over the place like it was Henderson and Eruzione lumped into one. Crosby scored the goal, so it fit the narrative perfectly... it wasn't even that great of a goal TBH. A save that Miller definitely should have made, considering the saves he made in that game. It is what it is.
The illusory truth was in full effect when I started seeing the media say things like, "Is Crosby greater than Gretzky?" and nonsense like that. It was so over-the-top but people still pushed it.
To me, Crosby was the best player in the world (off an on) since his rookie year throughout 2017-18. There were times Ovechkin, Malkin, Price, Karlsson, Kane made cases for being the best - granted, not for as long as a period as Crosby. But, he has two Hart Trophies over his career... so it's not like he had the MVP on lock-down like Gretzky did when he won 9 in 10 years. There is no way to justify that Crosby was the best player in the world throughout the entirety of his prime like Gretzky was, followed by Lemieux.
Despite the illusory truth and media agenda, Crosby won me over after his 3rd Cup. During that run, he literally put the team on his back at times, played an unparalleled full meal game, and showed incredible leadership. Even though I never drank the Sid kool-aid, at that point, I felt he established himself as the best player on earth.
Now, it looks like McDavid is cutting into that, and Ovechkin still continues to prove he is an elite force (and one of the best goal scorers of all-time).
