Focusing on the players involved a little more than the teams, you’ve got 10 teams getting a goal difference of +1.0 GD/60 or better with their first line on the ice. The players serving as first-line proxies on those 10 teams have tended to be Sidney Crosby, Nathan MacKinnon, Jack Eichel, Alex Ovechkin, John Tavares, Tyler Seguin, Mark Stone, Mark Scheifele, Connor McDavid and Nikita Kucherov. That’s a pretty good list of NHL superstar forwards. Stone is the most stunning inclusion on this list to me ; when he’s not on the ice, the Senators are a pretty horrific team.
