It wouldn't happen at any school above maybe a single A level
Well the schools I refer to are bigger than single A, perhaps some as big as AAAA, but mostly AA, AAA. As I mentioned before these are rural schools.
You do realize the state of Men's soccer in the US ?
We have a population of 325 million plus and struggle to beat teams like Costa Rica and Panama, whose populations are half the size of New York City. The best male athletes in America, largely, (not in every case) are playing other sports.
I agree that the best male athletes dont play soccer but even in the WPIAL (where soccer is bad and football is good on a per capita basis), highly doubt that any school bigger than A or maybe AA football team could beat the soccer team at soccer. Even at a place like Woodland Hills where the football team is usually very good and has multiple D1 players and the soccer team usually isnt, the soccer team would pound the football players at soccer.
Clairton doesn't have a soccer team but lets say they did, yea, thats a situation where the football players (best athletes) would beat 2nd or 3rd tier athletes playing soccer "for fun."
