hard it is to launder that kind of money and not get caught? It has nothing to do with reputability of the league or the Spurs and everything to do with them not being stupid.

If not money, what could they offer him that isn't money that wouldn't also land them in trouble?

If you do have some realistic ideas of how they might be doing it, I'd actually be interested in knowing, because I'm guessing that none of the small market owners would want to legitimize that type of thing. With the amount of money flying around, they're all heavily scrutinized.
