Why the Spurs do this:

Fox for three firsts that aren’t that valuable, plus you get rid of Keldon Johnson

Why the Kings do this:

Jones is a solid PG to temporarily start, and Jimmy could work with Sabonis and Keegan to keep up a good team.

Why the Heat do this:

They attempt to revitalize the careers of Huerter and Keldon. One of the better Jimmy offers I imagine.
