I know top guns draws players from one end of the island to the other, north and south shore.
Maybe so, but that's not the point. Tthe bulk of the players for TG are, as I understand, centered on the south shore around the Babylons. Furthermore, kids from those areas are much less likely to go to other clubs because of the high school coach affiliations. It's pretty safe to assume that there isn't a single Manhasset, Northport, or Ward Melville kid on TG.
