Round 2. I'll start off this time by clarifying that the specific rankings aren't the be all end all. They are made just using WAR. It is a 1.0 template list that could be further refined with the eye test and additional data.

That being said, here is the top 10:
McDavid
Crosby
Stamkos
Matthews
Tavares
Barkov
MacKinnon
Bergeron
Point
Malkin

Order may a bit off, but the players are pretty spot on. Point is the only one that didn't make the top 10 in the poll a couple weeks back.
