Look, it might happen in some states at some level ... I mean Texas HS have 40 million dollar stadiums. But in most areas, high school football doesn't mean shit.
There have always been high school cheaters ... mostly recruiting, paying for parents to move into a district, etc. The problem you have is there won't be the anti-trust aspect because there is no huge commercial value. HS football isn't going to suddenly get multi-billion dollar TV contracts. Coaches are getting paid millions.
You will get the Little Bron and Zeus type situations in basketball, but it will be the exception, not the rules. And because this is all local, the anti-trust aspect just isn't there to keep the schools from enforcing their rules. It's not mutli-state, so you won't have one state legislature passing rules that affect another.
