Miller looks to be the least likely. If I had to rank potential targets in order of most likely to be Dubie's guy(s) to least likely, I'd go:
1. Boeser
2. Horvat
3. Kuzmenko
4. Garland
I don't think Miller even makes the list due to his salary. But Boeser seems like the perfect Dubie target with 3 years left and seemingly just an afterthought there lately would seem to come cheapest in acquisition cost, and retention for 3 years is easier than 4 for Garland.
They probably want to keep Kuzmenko and would demand too much. But Horvat seems gone, and an easy one to retain.
I'd put an outside chance on Garland, but I doubt Dubie wants another smallish winger.
Yeah, Nucks seem to be good trade partners and ripe for the picking. Maybe they'd even take Muzz's contract as part of a larger deal if they're extracting prime futures out of us, just in case he has designs on returning.
