Probably no chance Hamonic plays. The guy opted out of the "bubble playoffs" because of Covid and his fears and liabilities there. He's rich as heck. He can afford to just take the year off and see what happens.
Hoffman scares people because he's going to want significant money and be worth it in terms of goal-scoring, but i'm sure he's narrowed an already shallow list of teams with cap space, down to very few...with his "reputation" re: the whole Karlsson situation.
Granlund will find a gig for sure. It's just a matter of how little he's willing to take, to find the right fit to rehabilitate his reputation after failing pretty miserably in Nashville due to a poor fit. Someone will toss him some cheddar to come in and score a few points though.
Haula will also find a role. Worst case, there'd be a line out the door of teams looking to sign him up as a versatile middle-6 piece with speed. Just a matter of waiting to see what the best offer is, which might take a while for teams to get desperate.
Brassard is a similar case to Haula, but lesser. Which should make it easier for him to find a deal somewhere. He's already coming off a 1-year "prove it" bargain bin deal...which means he's willing to go there. It's just a question of whether he's willing to go there twice in a row...and what sort of "team fit" he can find, to put himself in the right situation to succeed like he did in NYI.
Vatanen will land somewhere...but he's probably asking Top-4D money, when he played the last year like a #5ish bottom-pairing guy for the most part. He'll definitely find a solid landing spot though. Teams will always spend a little bit on a #4/5ish RHD with a history of being a lot better than that. It's just a matter of teams trying to sort out where to get the cap, and Vatanen realizing that he's either going to get kinda okay money...or be on a decent team. Not both.
Kovalchuk and Duclair, both probably on their way to Russia. Kovy is old and barely anybody wanted to sign him in better cap times for basically minimum dollar. He's one of those players who is great if you're a bad team, but terrible and useless if you're a good one. Nobody is going to offer him more than "filler" minimum price, and he'll be way better off just going back to Russia where he's a star. Duclair is a pretty similar player at this point. He can score goals on a bad team, but he's gonna be useless on a good team that already has better Top-6 forwards.
Chara is a huge wildcard. I kinda feel like he's gonna find a place to play. And i wouldn't be surprised if it's Vancouver based on the Benning connection. On some sort of 1-year heavily bonus-laden deal that pushes cap to the future.
