I don't ever see anything like that happening in the south. HS football is huge in Alabama, Georgia, Florida, Texas all the south really... in the last 10yrs its also turned into big business.
Even in a state like Alabama with teacher cuts, consolidation, and whatnot there are multiple 6 figure head football coaches. Coaches that only coach football too nothing part time with other sports or American history and math.
"I didn't come to Alabama to win 10 games a year and be a contender. I came here to win championships, Conference Championships, and National Championships. I love it here because that's not just what I want, but what this fan base expects." -Alabama Head Football Coach Nick Saban
