Being a High School head Football Coach is a 24/7 365 day a year job. The pressure to win in a lot of places isn't as important as winning with the right kids on the field.
Parents and boosters in some places can dictate all the way down to what kind of offense and defense you run all the way down to play calling. Admins will listen bc the parents with the political stroke also control their jobs. You don't have to just build great young men and win games Wich is hard enough. You also have to do it while swimming in shark infested waters for not a lot of money for the hours you spend and stress you put on your family and loved ones. No coach's wife and children should be hurt by the decisions of such boosters and political crap but it happens every day.
This is why young great coaches who could pore into the lives of their players for decades are getting out.
sad but true
