The trade would be done in parts because Cleveland is in the second apron.
Sorry for deleting several trade proposals, I haven't stopped making changes to the proposal π
Edit: Unpopular opinion, seeing how Cleveland's roster looks in this hypothetical scenario, I wouldn't mind signing Ben Simmons for the minimum to play a backup center role in limited minutes (during 2/3 of the minutes that Giannis wasn't on the court, it would be about 12 minutes).
A big man with playmaking and defensive ability, at least, could have an opportunity in this context). However, the medical team should perform a complete check-up of his back.
