I'm pretty sure that this is wrong.
As I understand the situation, the Lakers threw a low-ball offer, (like all the other teams involved) because they thought Kawhi was forcing his way out & to them. If they had treated it like a serious opportunity to get a MVP candidate, and put a worthwhile package together, I'm pretty sure that SAS would have taken the value. Just because it would have blown everyone else out of the water. For example, before the 2018 draft, offering:
pick 25 (made by LA for SAS), Ingram, Randle on an S&T, 2020 and 2022 FRP's
Would almost assuredly have got it done. As I understand it, what was put on the table was one of Ingram/Randle/Ball and pick 25 + filler.
