Here's some numbers: TG class of 2014 - 7 went to HU, all still there. TG class of 2015 - 5 to Hu, 4 still there. 3 from the class of 2016 going to HU. 2 from class of 2017.
In the next class (2016) there are 7 recruits, 4 from NY and 3 from MD. In the 2017 class there 7 total - 5 from NY and 2 from MD. Current HU roster is 30 players - 18 from NY, 6 from MD and 1 each from NH, OH, PA, CT, DE and MA. They lose 4 SR's after this season, all from NY. Next season they will again have 18 from NY but the MD total will go up by three to 9. Looking even further out, in the class of 2018 there are nine recruits, 5 from NY and 1 each from FL, MD, PA and NJ. All of this shows me that there is more diversity on the HU team than portrayed (most likely by YJ'ers). The evidence shows that SS is diversifying and adapting.
Look at any college wlax team in the hotbed areas and you will see that the majority of the players on the rosters are local.
