Why for all:

Bulls: Get their 1st back from the Spurs, a couple of 2nds, and are shedding a bunch of money from LaVine's contract this year. With the combination of Ball's contract finally dropping off, this would currently give the Bulls only $66M committed to the cap in 25-26.

Spurs: Explained this in another trade. Maintaining future picks and giving up minimal players in return. This is assume they get the Raptors pick and the Spurs pick is #4 or lower.

Cavs: Keldon is a good rotation wing. LaVine would definitely be a gamble, but he could potentially be a good fit as a #2 or #3 option with Mitchell at the point. The picks would give the Cavs additional trade potential, as well as the opportunity to add some young players to the rotation.
