Until Greece becomes more popular (or equally popular) in the US than the NBA, I don't see this becoming a problem.
We, as americans, don't really care about overseas sports...maybe that would change if marquee players go over there, but considering Soccer is the most popular sport in the world, and we don't follow Manchester United for instance, I am not too concerned about it.
We have had several MLB players that went to Japan to play, and no one cared. Granted none of them were massive names, but we americans are wrapped up in our american leagues. We didn't even care about the CFL when big named players went there and they are right next door.
