Unsure if you've seen this article, which was pre-shutdown, but it's got some FA salary projections.

C: Cirelli, Johansen are fine, and Couture gives pretty good production still at a high price. I think you can likely move him if you choose to do so.
LW: Draisiatl & Crouse are keepers. Drouin is okay at that price, he's maybe a 60 point guy, but no real peripherals. I'd want to move him if possible, but you have bigger issues. Nino needs to go, but is too expensive to cut.
RW: Carrier, Kassian, Vatrano, are all decent values. You can shop them, but you may not get much for them and Carrier & Vatrano are solid enough and cheap enough that they will help you. Kassian is older, but you might find he's better off being held by you than dealt for a poor return in the offseason. Zuccarello needs to be dealt to somebody interested in a win now move, as he's too expensive to cut.
D: Werenski is the only guy I'd really want to keep from your roster. DeHaan is not remotely good enough at that price. I'd cut Morrissey while you can before he becomes too expensive if you can't trade him. I'd hope someone takes Lindell off your hands as well, he has some misplaced name value, so that helps, as he's too expensive to cut. Look for cheap D that score some, but give good peripherals.
G: The Isles guys are fine, as is Petersen. I'd want to unload Quick if you can, but I doubt it happens, unless it's for a another bad contract, as he's too expensive to cut.
My main takeaway is that you have too many guys you need to cut that you can't cut:
Subban
Lindell
Quick
Nino
and some others that could join this list.
