This is a bold scenario, I know lol. But if somehow the Heat could pull this off it'd be a wild offseason. For this hypothetical scenario to happen the Heat would need to convince Lebron that they'll both draft his son with their pick and pay him for 3 more years (equal to the reported offer the Lakers are willing to give him).
On the other side, Mitchell would force his way out of Cleveland and Miami sends a very good sophomore in Jaime and a nice SG in Herro + a 2026 pick to make their offer attractive and solid enough to further strengthen a young talented team like the Cavs.
Additionally, exchanging Rozier for Sexton would help their defense and playmaking at the PG position and since the Bulls are hitting the reset button they might entertain the idea of getting younger and productive players to revamp their system.
