If the Spurs "avoid them like the plague" they wouldn't've even had Crawford in for an interview. Basketball more than most American sports is meritocratic in terms of talent over background. But all sports are filled with athletes who were privlieged to have access to the training and stability that are often lacking in "the hood". What this means is that there are a bunch of players who are not uber-talents but who are trained well who end up being the solid player the Spurs are in a position to draft every year. They've never shown a tendency to hold a player's background against them. Now, are there "real n-words" that the Spurs avoid? That's more likely. But as you know, black people are not a monolith, and there are plenty of black boys from the hood that don't carry the stereotypical at ude with them, just as there are middle-class black kids who develop that at ude (like Ja).
I feel like there's a certain burden of proof that goes with the charge that the Spurs care about background at all. There are situations like with KPJ that the Spurs chose to pass up on talent that came with baggage, but they haven't turned out to be bad choices. It's not like Haliburton, Jokic or Sengun were passed on because of their street reps.
