from the way I understand it the timeline went something like this (THIS IS MY INTERPRETATION)--Blair Academy in Blairstown NJ has been the perennial national champion in wrestling for over 30 years. Although they always had kids from all over the nation wrestle there, they always had about 60% (depending on year) of their team consist of kids from Eastern PA, NY & NJ. They had the pick of the litter but over time the local private Catholic schools built up their programs, especially Bergen Catholic (my alma mater). Our program has now taken a fall & Delbarton has pretty much taken the mantle. The talent gap began to close and it culminated in 2018 with BC defeating Blair for the 1st time. Many of the top BC wrestlers would no doubt had been at Blair a decade earlier. So the next year the Blair team became somewhat more national as they went out and aggressively recruited and lo & behold they land California State Champion Dominick Matte from Poway. Blair was the evil empire that everyone already hated (I would kind of think how Mater Dei is perceived in football). This recruiting coup was tantamount to pissing on a hornets nest, for the Cali wrestling community went parabolic and in their haste got this rule passed. But it wasn't just wrestling it was for all sports. In wrestling it has had a profound effect on tournaments as the Cali teams no longer go to the #1 tournament in the nation the Walsh Ironman in Ohio because Blair and other prep teams are there. Hope this gives some clarity.
