Every team gets what they want/need.
Suns flip their picks and Ayton for an all star (Siakam) and a back up playmaker (Reggie Jackson) for when CP3 is on bench or injured.
Kings give up future unprotected picks and D.Mitchell to invest in core they have now while adding a defensive stopper (OG) to the lineup.
Clippers get a new starting PG that played with Kawhi In Toronto and a shooter/defender in Crowder, and a backup Center in Holmes.
Knicks flip Fournier contract with a protected 1st from Detroit and 2 future 2nds for a spark plug/shooter Gary Trent Jr.
Raptors do this if they want to buy into a rebuild. Multiple future 1st round picks, D. Ayton, and Davion Mitchell while keeping Scottie and possibly drafting a player like Scoot in this years draft… Pretty good imo.
Btw I get multi-team trades rarely work out for all teams as well as teams don’t want to improve other teams so therefore multi-team trades are unlikely, but as fans we can dream
