Thing is, nobody on the planet would ever consider taking 4th line grinders from a dynasty over McDavid. They aren't comparable players. Not even if they had won ten straight cups. You need someone comparable, IE Crosby, to really make the cup argument come into play.
Fair or not, and it will especially come into play even more if the 2024 postseason is similar to last year's, there are people who would take Eichel over Matthews when it comes to postseason play and who suits a team better.
Is Matthews better? Yes. Would I take him for certain over Eichel once the postseason starts? I would need to really think about that one.
