McDavid in a walk - no disrespect to Sid.
The argument is going to be playoffs. McDavid is excellent in the playoffs - he just has shit all (besides Draisatl) to help carry the load. None of those middle six guys who elevate their game, no defenseman that just makes sure nothing happens on either side of the ice in their 21 minutes, no goaltender to keep the game close.
Playoffs are *very* important when rating players in the NHL. The way schedules work, divisions, deployment - there's a lot of noise in the regular season. But when you're facing one team for 7 games, that's when you have to elevate. And to McDavid's credit, he does.
