Not the first person to have this idea but like... why wouldn't the Sixers and Heat swap their older, overpaid star wings?

Philly reportedly tried to trade for Jimmy this offseason before going after PG

Jimmy and Embiid are good friends, would also hopefully light a fire under Embiid

Heat get the slightly younger player under team control for three more years, they're able to remain competitive (which has clearly been their goal)
