The only one that comes close to making sense, is the Celtics because it involves another star player and lots of picks. Even then, I think the Spurs would want one of the Celtics young guys. The Lakers makes sense if it's Kuzma and Ingram or maybe even Ball and Ingram plus picks. But things would have to be irreparable between Kawhi and the Spurs (like Kawhi threatening to sit out next season kind of irreparable) and Kawhi would have to try to force his way for them to give it serious thought. Especially since you know the last thing the Spurs will want to see is Kawhi in a Lakers uniform.
