That's an impossible roster.
As explained here:
https://projectspurs.com/2018/01/18/...cap-situation/ In order to open up a max spot for Lebron, the Spurs have to renounce all their RFA (no Bertans), and all their players with an option opt out and leave (no Danny and no Gay either)...
If you read the article, (I recommend it btw.. outside Chinook, I don't think anyone else has been that thorough explaining cap intricacies) you will understand why Lebron in San Antonio is a fantasy... add in Kawhi's injuries and it's just not going to happen.
