Especially knowing Matthews is not dominating five-on-five play at the level the Leafs need him to, why they turn to him so often to start PKs alongside Marner continues to make me scratch my head. Save him up for a big post-PK shift with totally fresh legs. Kampf-Marner has a long history of reasonable success together, they now have Laughton-Jarnkrok as another pair, and they can still mix in Matthews here and there with Knies when they want to (or with Marner if he’s taking another shift later on in the kill).
