I actually think this is the future of high school football. The really big-time players are eventually going to join literal minor league type football programs for kids (this doesn't really exist yet), and those programs are going to be an entirely separate entity. The actual high schools fielding "extracurricular" sports will form their own leagues where most/all of the players are just typical high school kids who aren't seriously thinking of trying to be a professional athlete. Schools and big money minor league sports need to be separated.
He didn't appear to have a choice in the resignation.
These young and/or unknown coaches who come into very average or less programs and suddenly schedule these huge opponents should be watched very carefully. In nearly all cases, one of two things is true:
1) the program recently implemented is really good, and the program can be expected to be a major player in the future regardless of their past
2) some goofy, tricky, possibly illegal or fraudulent stuff is going on.
