A pretty interesting topic and discussion that the usual fan boys have devolved into yet another pissing contest.
It all comes down to health. I don’t see how he doesn’t win at least 1 more if he stays healthy. Until/if Chicago gets their act together around Bedard, I do not see a legitimate young contender for being a perennial threat right now.
I think for the next 3-5 years the winner will be between McDavid, Mackinnon, Draisaitl, and Kucherov. There are some guys in the tier below who could take the next step or have a big year, but if all those 4 are healthy I think they will have it nailed down. They should start noticeably slowing down after that window.
