I believe San Antonio will continue to try to make amends with Kawhi, in hopes that an extension can be signed. I also believe that most teams will not offer much based on the rumor of Kawhi bolting for LA in one year. Can San Antonio allow select teams to talk to Kawhi, so that other team can get a better feel of his intentions and if he is willing to sign an extension when he hits free agency (so that he can sign for the extra year and more money)? Boston can make a recruitment pitch with Danny, Brad, Wyc, Kyrie, Gordon, Al and even Pierce (who was also born in LA and could relate to Kawhi).
If teams can't talk to Kawhi, I would think San Antonio could only expect to get back maybe 40-50% of a return. If teams are allowed to sit down with Kawhi, maybe the rate of return goes up to 75%. Since Kawhi is a top 5 player, it is almost impossible to get back equal value.
