Everyone here is way over analyzing empty net points. Last year we all thought it would be a tight race and most leaned towards Kuch. MacKinnon won in dominating fashion and his multiple 30+ point 19 game point streaks had a lot to do with it.
He had Makar (90) and Rantanen (104) last season too. If anything, losing Rantanen this season should give MacKinnon more votes.
Leon obviously has McDavid "only" which IMO will always be held against him, but Matthews won the Hart with 60-46 being 17 points behind McDavid. That year IMO McDavid/Leon cancelled each other out and Matthews won pretty convincingly.
Going off that all, I think Kuch may sneak away with it this year. Its pretty balanced after him for Tampa and obviously he is the common denominator.
So my vote today goes for MacKinnon, then Kuch, then Makar.
I really think the 60-60 argument for Leon is big, but same can be said for Makar if hits 30-70, or even 35-70 which is very possible. 100 points for a dman is massive
