The intriguing part of the Clippers is that he asked to go to the Lakers. You could trade him instead to the Clips. It's LA. Same home court. Clips are very cash strung and if the Spurs signed hand traded him under a max contract whilst taking their 12 and 13 picks AND Harris, you would effectively be blocking that team from getting substantially better for years.
They would certainly have a hard time opening up cap space for another max player which is what he would need to even think about competing with the Warriors.
Meanwhile, the Lakers will in turn go balls in on PG, Lebron, Cousins, etc. Expect them not to have any cap space to do much else either.
