I think it would be possible but it wouldn't be that type of trade. It would be 1 of 2 things, the Kings want to also move Gay, but the acquiring team doesn't want Gay, so Boston steps in and acquires Gay for Zeller and a 1st (like Boston's 2018 1st lottery protected). Or the Kings don't want one of the potential assets (for fit or whatever) and that player ends up in Boston with a better fitting player or draft pick ending up in Sacramento (like the Kings end up with Brown/Smart and player X ends up in Boston).
