There's a very big gulf between the opinions of those who saw Mogilny before injuries greatly affected his career, and those who are primarily familiar with his later career (part of Vancouver, NJ, Toronto).
He had a lot of injuries: multiple broken legs, major knee and hip injuries, I think multiple concussions...
For almost everybody who saw Mogilny at his best - in the late '80s and the 1st half of the '90s, he is a very easy hall-of-famer. Everybody thought they were watching a future inductee, without a doubt.
These are the ppg leaders for '92 to '96:
1. Lemieux - 2.26
2. LaFontaine - 1.48
3. Lindros - 1.46
4. Gretzky - 1.42
5. Oates - 1.39
6. Mogilny - 1.33
7. Jagr - 1.33
8. Selanne - 1.32
9. Sakic - 1.31
10. Yzerman - 1.31
This is the Mogilny we remember. For me, he is an essential HHOFer, one of the most skilled hockey players ever.
I suspect he would've been drafted 1st overall in the '87 draft if available to play in the NHL. And he is one of the best WJC performers ever. I first saw him play in the Piestany tournament.
I can understand people who weren't around in the early '90s, and aren't impressed by 1,000 points, but with normal health he likely has 1,400 or 1,500.
He was too good to not make the Hall, and he will make it. There has never been an NHLer as talented as him who's not in the Hall.
He is among the very best skaters in the history of hockey, and among the very best shooters and goal-scorers in the history of hockey.
