The Cavaliers do this trade for the reason below

1. They get some draft picks

2. They could be high considering how bad the Thunder are

3. They would not do this in a heartbeat because they are protected

(If you do not know what protected draft picks they mean that for example if the thunders pick was out of the top ten in 2023 the year I gave them the pick they would lose it if it is the top ten they would keep it so its a gamble)
