I wouldn't put him at No. 2, but man, I don't know how people can scoff at placing him top 3-5. Stats are skewed due to COVID, but he was gliding towards 110-115 pts last year and is on pace for 120 this year if they played 82. He's incredibly consistent. Last two seasons, who else besides McD and Drai have put up as many points per game? Not many.
I think Panarin is at least in the top 5 and if he continues what he's doing, he will be solidly Top 3. Yes, even ahead of Kucherov. Panarin's linemates have been Ryan Strome, Jesper Fast, Kaapo Kakko and Colin freaking Blackwell, FFS. The numbers he's putting up are incredible, all things considered.
Obv, if you want to look back more than just this season and last, different story. It really depends on how much body of work you need to make definitive statements about who ranks where. I just think Panarin's getting to the point where he's forcing himself into this conversation in a real way.
