No doubt Philly area is a respected hot bed for recruiting. But you need to check your numbers in regards to Long Island my man. Where are you getting your numbers? Several kids in 2016 & 2017 from LI that are committed aren't listed on a couple of sites. Not sure about your comment of "isn't even close". The list below could be off a few players.

Long Island D1 commits-
2015- 12
2016- 15 (Hop, 2 to Cuse, Mich, Duke, 2 to PSU, 2 to Army, Nova, SJU, AF, Bing, 2 to Hofstra)
2017- 9 (PENN, 2 to Hop, Bucknell, UVA, G'Town, Fairfield, Boston U, PSU)
