I live in Brooklyn, and people in New York City overall take themselves way more seriously, than any else does. The reason why this isn't an issue is because no one cares, I've never thought of NYC as the point guard Mecca. Sure there are a lot of good ball players here, but there's a lot of good ball players in every big city.
There was a commercial this season on the Knicks channel I believe, and it led off with the line, "Here in New York we think we've invented everything about basketball..." The statement wasn't followed up with a reason why this was true or untrue, it simply continued as if that was a truth. Anyone that knows anything about basketball knows it was invented in Springfield Mass, and no matter how many point guards come out of New York, that's not going to change.
