Cap fit actually works okay given Minny already has some cap room and if they send down a player and move Hartman to LTIR, they get close. Probably have to move Dumba in a separate trade which they should probably do. I'm sure someone would take him as an expiring right shot UFA. Maybe a little bit of retention to help Minny get through the next couple years with the PArise/Suter buyoutsNot sure there's a cap fit with Minny & Kuz. There's Dumba but he's fallen off a good bit and is similarly buyer beware. I mean, I guess returns could be worse if they mainly want to get out of the term remaining (and I would think cap space would be the primary asset gained). It makes some sense with Kaprizov there but the Caps aren't going to want to retain if that's what it takes. And Guerin is probably not primarily interested given some of the question marks with the player and their tight margins due to dead cap buyouts.
It's more of an off-season move and even then there's probably only a handful of teams that make sense. Maybe Montreal. CBJ if he's open to playing with Gaudreau. Chicago.
Minnesota is a decent fit because they need a top 6 center and have attractive assets with plenty of defense and forward prospects. The fit with Kaprisov is also nice and they could have Yurov and Khusnutdinov in the near future. They might like to be more "Russian friendly"
Otherwise, yep it's probably an offseason move. Chicago makes sense as well
