Have the Spurs given other teams permission to talk to Kawhi's agent? If not, I can't imagine any deal is close. This despite the fact that the C. Paul trade was agreed to on the 28th of last year, George was traded on the 1st, etc.
An added confound is that Kawhi's uncle is his 'agent,' though I think it's unclear if he's his primary agent or not. If the latter, teams may have been bold enough to have already had discussions with his camp. And the Lakers have been calling him for months, regardless.
