The best deal is now. Here's why:
Currently you get your pick of the litter from LA. After this the best case would be pick of litter from Boston who will be less inclined to give a haul once Rich Paul insists to every trade partner that he will be a one year rental only.
This isn't a case where a team can realistically hope to keep the guy. He literally hired Paul to get him to LA and Paul has other business interest that will insure he does just that. After next week the market lessens to reflect one year rental rates. And when Kawhi leaves Toronto and teams see the real cost of one year rentals it will be even more of a depressed market.
Demps got Pop in his ear poorly advising him. Meanwhile Pop let his ego screw him into only getting a 30 year old guard who can't shoot for a top 3 player in his prime.
NO need to take Magic to the cleaners while they can.
