Poor choice of player comparaison.
Yes, at that point, Marner might be a better player offensively compared to Crosby, but Crosby brings more leadership and defensive play to the table, which is not the case for Nylander vs Ehlers.
Kucherov has been injured all season long so I don't see your point.
MacKinnon is pacing for 102 points this season over 82, while Marner is pacing for 103 points. There are pretty much equal as this point. Clearly not the same thing as for Ehlers vs Nylander 20 points gap (pace wise).MacKinnon has the best resume, so of course he would win a poll, which is not the case for Ehlers vs Nylander (they had similar career before this season).
