In the context of a thread claiming MacK is definitely the best player in the world, I think a 5 point difference over a full season is significant. Especially considering the 13 point difference in ENP that you mentioned. I realize this thread was started by a pretty obvious McDavid hater but still.
Fair enough. I think it’s close enough where other factors could push a player ahead to being the best. I do think MacKinnon’s play driving and 5v5 production pushed him over Kucherov last year even though Kucherov outscored him by 4 points for example. Though I think McDavid has been the better all around player in this time period.
