Whoever acquires Kreider is in for a bad time, unless it's something like Perron for Kreider.
He is about to fall off a cliff. Add in that he clearly doesn't want to be traded, to the point that Friedman claimed that Kreider is calling teams to disclose his injuries and dissuade them from trading for him.
So whoever gets him is getting a declining hurt player who may not be that motivated based on the circumstances.
If they trade him without cap coming back, it will be something like the Trouba trade. They will get a late pick.
