It pains me to say it as a Leafs fan but Matthews and Eichel's gap isn't as big as we're making it out to be. After returning for injury, Eichel scored on a torrid pace and is more of a backbone of the Sabres' scoring whereas Matthews, although important, doesn't have the same pressure. With that said, this is gonna be close...Eichel and Matthews are near equals in terms of scoring but in terms of having an overall impact on a game, Matthews wins.
As for Karlsson, the man is a machine. I was thinking that the injury would slow him down and make him seem mortal... and even after all that, he's still in conversation as amongst the league's best. Ridiculous.
