Its a tough decision between Mackinnon and Draisaitl. I've always said Mackinnon to this question before, but it's impossible to argue with the results that Draisaitl has been putting up for the past 3 years now, and the trophies that have coincided with that insane production.
I think Mackinnon needs to have his year, like Draisaitl did last year, where he sweeps the awards and the players see him at the best player and he can more unanimously be known as the 2nd best player in the league.
Kinda disingenuous that OP listed the reigning Hart, Art Ross, Lindsay who is currently 2nd in the league in points, as the last option for this poll- behind Marchand, Pastrnak, and Ovi who really don't belong in this conversation at all.
Really the front runner options for this poll are Draisaitl, Mackinnon or Hedman, they have a slight gap on the next tier of Kucherov/Crosby/Panarin/Kane
