Coach, AGAIN you miss important points. Many FB coach/ADs in our state -- across enrollments -- DON'T teach. And many of them are nothing more than nominal ADs to supplement their salaries. (Thankfully, that is slowly changing, as more schools are separating the two positions IN RECOGNITION OF the problem.)
Your point about attendance, selling newspapers, generating revenue, etc., is relevant, as far as it goes. But isn't it amazing how so many of those football-crazy states lag behind their peers nationwide in public school student-body academic performance?
The 6-figure salary of a FB coach/AD at a mediocre academic institution is a legitimate concern for anyone who pays taxes.
