I never had an issue with empty net points. They pretty much guarantee a win.
As for hart favorites, I'm not really sure who would win right now. But I expect some of the leaders to distance themselves by year end.
The 4 most obvious contenders are McDacvid, Kucherov, MacKinnon & Draisaitl by virtue of being the 4 best players who also happen to be contenders at the halfway point. But it'll depend a lot on how the 2nd half plays out.
Drai and McDavid have each other, and McDavid has voter fatigue, hurts the votes.
MacK now has voter fatigue (won last year), and also has Ranta (phenomenal season) and Makar, which hurts the votes.
Kucherov - voters don't like him as much for some reason.
It's still wide open. There are other contenders too, but I expect one of, or a few of these 4, to distance the pack in 2nd half.
