This one is a bit silly as the Celtics aren't likely to blow up what they have going. But this gets them two good long term starters while reducing long term payroll (Resigning Grant Williams and extending Jaylen).
I think the Hawks say yes to this. They get a solid PF and 1st rd pick along with guard depth - in exchange for Collins who they seem to want to move on from.
Suns get a star player and a solid young PF. It would cost them picks and change their team a bit, but it may be worth the gamble.
