I don't think Blackhawks are impossible to fix. Assuming they get a top 2 pick this year, they have a 2c next year. Toews is only 30, he's got a lot of good hockey in him still. The forwards are only a Kaapo/Hughes and some tweaks away from being competitive.
The d is a bit of a dumpster fire at this point (especially with age) but I like Boqvist and Entwistle (edit: I meant Beaudin) If they can add 1 more solid piece there them it may be usable. Cap will be the issue for sure but it's not impossible.
DeBrincat - Toews - Kane
Anismov - Hughes/Kaapo - Saad
Step forwards from Strom, Kahun, Kampf, Perlini
Entwistle makes the team
On D
Keith - Boqvist
Jokiharu - Seabrook (until replaced with a better option)
Beaudin - player of the moment
I could see their retool being quick, they might feel Toews and Kane can carry them to another cup. Doesn't seem like they have another cup run in this roster but I can see them trying for a quick retool.
