Barring some late season cold streak, if Kucherov doesn't win the Hart then the pendulum has swung way too far in favour of 'great players who aren't the best but their teams squeak into the playoffs'. Sort of like how the Jack Adams rarely goes to the coach of a President's Trophy contender, which is similarly dumb.
I'm already totally against excluding non-playoff team players from winning the Hart, so if players on great teams start being punished as well then the award loses a lot of credibility to me.
