You are quite the optimist. An enviable quality in most instances, but not on CapFriendly, lol.

Tony DeAngelo at 2.5 to play on the bottom pairing behind Andersson and Tanev is actually super interesting. I don't know if I would be willing to part with a second for him but it's an idea that if on the table would deserve some thought. Especially if Kylington comes back next season:
Hanifin - Andersson
Weegar - Tanev
Kylington - DeAngelo

Other than maybe, maybe Calgary, I don't think these make sense for the other teams involved

Avs aren't trading a young, cost-controlled C that is starting to come into his own for Hayes

No chance that Colorado does that, if for no other reason than cap inflexibility, and Los Angeles doesn't need another bottom-6 forward when the Kings have about 8 of them trying to find playing time now -- and four of them are Alex Iafallo, Quinton Byfield, Kevin Fiala and Arthur Kaliyev.
