Strome-Terry worked, go back to that. Maybe Killorn on the other wing because Vatrano wasn't doing much there so Killorn would fit right in.
Zegras and Cutter looked dangerous, so pair them together (though Gauthier looked good on the 4th line too, got assist on the first goal). Pair them with Vatrano. See if they can get Frank going (he's been streaky historical, right?).
Carlsson need someone to take faceoffs for him and Lundestrom can do that and it's fast. Colangelo has been scoring at the AHL level, sounds like he deserves a call up.

Gives each guy that likes the puck in their stick his own line. Also, someone will get easier matchups, and that top line may not be horrible defensively. There just isn't much depth on this team, and very little chemistry. Cronin needs to put the guys that show a little together.
