If Bill Armstrong can talk Provorov into extending there then I could maybe see a Maccelli-Provorov swap.
The Jackets desperately need forwards and Utah D. I'm not sure if this works for the Jackets - Provorov is at his best right now and has been a big part of their early season success. Without him they run out of top 4 options pretty quick. Maybe if they're ready to call up Mateychuk.
I highly doubt Utah would have any interest in Provorov, and I don't see how Maccelli's value would be that of Provorov. Maccelli is a solid top 6 player who is decent but not great defensively and has no edge. It's not like he has negative value at just recently 24yo on a very solid contract for 2 more years. He could easily become a PPG player (has already been pretty close to it) and is already an exceptional playmaker at minimum. Not really his fault that he's mostly played with Crouse on the 3rd line.
Andersson I could definitely see as UHC is weak on the top pair and Andersson is exactly the type of d-man they'd be looking for who can play defensively. OTOH I would imagine those talks have already happened so I doubt much has changed.
I don't know what UHC would realistically want from MTL that would be newsworthy. Maybe Laine if they think he bounce back somehow but I kind of doubt that. I can't see Matheson being the ask considering Sergachev is already there and his age. I also can't see any of MTL's top 6 being available so...
