Frankly, this is probably blasphemy on these boards but I don't see why MacKinnon is considered to be in a different tier than Nikita Kucherov.
They both joined the NHL in 2013-2014, with Kucherov starting on the 4th line and MacKinnon already in a prominent role. The way I see it, MacKinnon took his step forward in the 2017-2018, when he broke out for 97 points, so that's where I'll draw the line for comparison. Kucherov also took a step up that season, and both turned into the players they are today.
Pre 2017-2018:
MacKinnon - 0.687 P/GP
Kucherov - 0.821 P/GP
2017-2018 to today:
MacKinnon - 1.295 P/GP
Kucherov - 1.361 P/GP
Since their rookie seasons (unfair comparison with Kucherov scratched/on the 4th line), MacKinnon has outpaced Kucherov a total of 2 of 6 seasons, one of which was by 0.06 PPG.
Even MacKinnon's (career high) pace this season is slightly lower than the average of Kucherov's post-2017 pace.
Sure, there are other arguments to make for MacKinnon and he plays a more valuable position, but I'm just unsure why it's such a foregone conclusion that he's in a higher tier than Kucherov when Kucherov has the clear edge in production.
Anyways, I voted Hedman.
