That's true - you're right the one spot he does seem to recruit from more than others is St Augies. The Hun kid was a flip from Princeton (and played in my son's travel program), but never made it as far as I can tell (he was supposed to actually coach my kid's team in the summer but didn't do that either, or else I'd have asked him what happened lol).
But considering how most of the talent and the best lacrosse schools are in North Jersey, he doesn't really hit those prestigious ones much; like Delbarton, Don Bosco, Bergen Catholic, Seton Hall Prep, Pingry, Lawrenceville, or even the top publics like Montgomery etc.
My son plays for a big group 4 public in the South, and I can admit that even the best south teams (St Augies, Lenape/Shawnee/Moorestown/Haddonfield in the south) usually get blasted by those northern teams when they play them. There is just more talent up there (more people, much stronger lacrosse culture, etc.)
