I thought about the Bucks, Giannis was still homegrown, albeit with a later pick. We also had that with Kawhi. I probably could have phrased my post better.
I don't see the Spurs, or any small market team, attracting anyone with superstar talent until said small market team is competing deep into the playoffs on an annual basis. Until we're very relevant, no significant FA will come here. Even when we were good, most FAs didn't choose San Antonio...certainly no superstar level players. LMA was really the only one, and it's arguable as to whether he'd fit the superstar category. He sure seemed to be on the fringe of that status in Portland.
