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.
That seems to be the new business model at PT, and please do not forget these are businesses. How do you attract kids to your program? Market the number of committed players you have on your rosters. Who is most likely to be committed and early? The holdbacks and they were obviously added to rosters this year.
