I'm curious of people's opinions on the topic (hoping un biased both ways), but Matthews scored 50 goals in 50 games. The first since Lemieux in the 90's, but the NHL only recognizes 50 in the first 50 games as a thing. Personally I think 50 in 50 is the same thing, but I suppose my take doesn't matter to the NHL. Read a cool article on the topic and it was funny.
A paragraph in the article must have been written after interviewing @Vegeta though...
And at this point, I don't even know if it's [? just ?] because there's, like, a whole-- it's a rivalry thing. Like, I don't understand why non-Leafs fans are so hesitant to say, hey, Auston Matthews has 50 goals in his last 50 games. That's pretty cool. I don't get it. Now it's turning into, like, oh, no, he actually didn't. Cole Caulfield is better.
