I think straight expirings is close. Maybe Favs and Crowder... or expirings and a second. Outside of Sacramento I can't think of a team that would want good players on longer contracts and would offer salary relief. Favs is a pretty significant upgrade over Gortat for them.
I'd definitely do it for expirings and a second. I'd probably do it for Favors and Crowder too, although with Gallo's injury history I'm not sure I'd want to give up Crowder. Maybe they'd take Favors and Thabo?
