I've explained this. There's no scorer that can replace Kawhi available. The cost of a scorer that can't replace him is going to be Siakam, +
You can get someone with a shit contract for less (Wiggins, Love) or an injury reclamation case (Hayward), but I don't see the point. Turn Gasol & Ibaka into younger, rotation worthy bodies and picks, do the same with Lowry if he's willing. Play those younger guys heavy in a good system run by a very good coach. Build the value of those assets and flip them with picks for the next disgruntled star that comes up in trade talk (hello KAT), and then take a run at 2021 free agency with Siakam and said formerly disgruntled star in tow, and try to add a legit piece to the mix with cap space. Quickest, easiest way to get back to contention. There is no path to contention that starts with replacing Kawhi this off season.
