I mean, Lake Erie is right there...
Would be a bit crazy, but I can see the merit for both sides.
Lakers get a young lead guard signed for multiple years. They also get an All-Star Caliber C that would let AD slide back to playing PF. Along with that, they get some expiring money.
Cavs get LeBron back, plus a better fit as a secondary ball-handler next to Mitchell in Reaves. Rui either starts or comes off the bench as a 3/4.
