This may be true in Long Island, but how many Lax Clubs in Westchester are owned by HS head coaches. I don't think there are many. I can name just two: Superstar and Westchester Warriors. Are there others?
One could say Prime Time, which is run by a John Jay assistant coach, but other than a few token John Jay kids he carries, (who are generally the weakest on his teams) he's become all about the repeat/prep school player who are more apt to be recruited.
