I would accept Knies and Wolf for Chychrun easily, without the 1st. No question.
Let's take out the 1st, for now. I'm also wondering if Hanifn and Muzzin need to be in this? Let's just pull them for a thought experiment.
CGY: Nylander
AZ: Knies + Wolf
TOR: Chychrun
CGY is now only giving up Wolf to get Nylander. That seems like a bargain. Meanwhile, Toronto has to give up Nylander AND Knies just to get Chychrun. Maybe AZ retains 50% on Chychrun to make that worthwhile for Toronto? And maybe Calgary pays Arizona a 2nd and sends Dube to Toronto to replace Nylander?
CGY: Nylander
ARI: Knies+Wolf+CGY '2nd
TOR: Dube+Chychrun(50%)
