Good to see even if chances are low, that the Spurs are doing literally everything they can to fix this.
Smart on their part for a couple of reasons:
Worst case...they lose him, but show their fans (and other possible FA's) that they did everything they could to repair the relationship. It also provides them with a little bit more leverage to drive up the asking price when it comes to a possible trade. Especially if they can give the impression that Kawhi is thinking about staying.
Obviously, best case, they work things out with him and continue on as usual.
