Marner and Nylander are 2 completly different type of player.
Nylander when he's on, he's flying on the ice and looking like maybe the best player in the world and making producing player around him. When he's off, he's making thing harder for everybody on the ice. That's make him a pretty hard player to play with.
The difference between last game vs MTL where he had been fantastic and previous ten game was not his teammate and who he played with, it was his own level of intensity.
Even in the game vs NJ where he finished at 2 goal and 1 assist, his intensity was pretty low but he's a tremendous skilled player and a fantastic finisher, so he still found a way convert his scoring chance.
