I don't really think it matters re: Jarry and Graves anymore. At worst, they're just eating roster spots/cap room for this team to take advantage of being the "trade us your trash for picks/prospects" angle while they wait to rebuild.
But they're not like, pay to remove players imo. Who gives a shit anymore?
I think as far as value goes, in no particular order; Rust (once his NTC drops), Rakell, Petts, Puljujarvi, EK, Letang (if he's willing to waive, but asking him might make Sid frown and we can't have that). Those are the guys you might still be able to actually get something back for. Guys like DOC, Bunting, etc. are probably worthless. Guys like Jarry and Graves are not worth paying to remove.
I think your TDL moves are Petts, DOC, Puljujarvi and maybe Rakell if he's willing to waive (though he only has an 8 team NT list). Might not bring back a 1st, but probably a couple 2nds and some prospects in the Broz/Koivunen tier.
Your off-season moves are Rust once his NTC drops, EK, and explore a Letang deal. Gonna have to, without question, retain 50% on EK for any move, let alone value to come back. Might be smart to retain on Rust a bit too just to open up the market for him--a Rust on your 3rd line at like $3.5M AAV is probably a player a lot of teams are in on.
But for the love of god, fire Sullivan on April 18th. Don't even let him have influence on the draft or off-season moves, man.
