If I were laying down a bet on the trade return, I would guess it would be a 1st round pick, some secondary asset that's worth less than that pick, and a relatively inoffensive cap-dump (one which doesn't have more than a year or two left on it, and most of the cash is paid out already).
As a Coyotes fan, I hope all of this interest drives the price up from there, but that's roughly my expectation.
EDIT:
NOTE: 9/10 of my fellow Coyotes fans will disagree with me on this. But for me, someone with pretty low trade expectations, I'd offer these as examples of the minimum baseline for my expectations:
EDM'20 1st (14th), either Raphael Lavoie or Dimitri Samorukov, and Kris Russell.
CGY '20 1st (19th), Dillon Dubé, and Milan Lucic (with significant retention).
BOS'21 1st, Urho Vaakanainen, and Nick Ritchie and/or John Moore.
These aren't exactly equivalent but meant to represent more of the TYPE of thing I'd expect in a package. None of them are thrilling. Most Coyotes fans would be crushed with those returns. As long as we don't get less than that, I won't be rioting in the streets. None of them are appealing, though. More like the nasty medicine I know is coming.
