Orlando needs to clear out the glut of front court players. And they are going to most likely resign Vucevic. Because of this I can see aaron gordon becoming available for a proper wing.
So....
Hayward to Orlando - Orlando get a wing that can run the show, set players up and take over games.
(Out Gordon amd Mozgov)
Nop gets Gordon, Tatum, Mozgov and LAC pick, Boston Pick 2019 and 2021 - Pels add 2 young guys to build around with Holiday. Picks and players locked up. Mozgov a large expiring (out is Davis and Moore)
Boston trades Hayward, Tatum, LAC pick and Boston 2019 pick and Boston 2021 pick and get Davis and Moore.
Boston lets the wing be defenders and will count on defemse/playmaking from the trio of Smart, Brown and Horford. 3 guys who have shown they can fut in a lesser role. Irving and Davis are the studs of the team.
The Memphis and sacramento picks stay with Boston for the bench
