Most post-1945 .800+ GPG seasons happened during 1980-1994. They didn’t all win the Hart because they all scored .800 at the same time, often losing to Gretzky and Lemieux. Or they didn’t score 50 goals. Or it had been done the year or two before by someone else, diminishing the specialness. Or their teams didn’t win enough.
Completely different for Matthews. He’s the first to do it since Mario Lemieux. The passage of time makes it historical. And it’s not just his .800+ GPG that makes him Hart worthy. It’s everything put together. His 50 in 50. His 60 in 73. Both of which also haven’t been done since Mario Lemieux. His team’s regular season success. His 106 points in 73 games. His elite defense. Leading the league in goals, goals per game, even strength goals, shots, takeaways. And then add in the rarity of .800+ GPG. As I said, in terms of rarity, that’s like scoring at a 144 point pace.
You can pick any one thing apart, sure. But in totality, and given his competition, that’s probably a Hart winner in 2022, and no amount of “well, the Art Ross winner usually wins 2/3 times” or “historically, if x then y” will account for Matthews’ historical season.
Taking everything into account, watching Matthews hit one historical milestone after another, my guess is he locked up the Hart the moment that puck went in the net for the 60th time. McDavid is probably his closest competitor, and I’d imagine nothing McDavid does from now until Friday will move the needle. The season is essentially over.
