re: For non P5 teams, why has the triple option generally not expanded beyond service schools?

Yes some other teams run it, but it is still relatively rare even among “inferior” teams

I just feel like if you are miami Ohio and you are facing a big ten team your first game, as you often do, you’d have a better chance of springing the upset if you were a triple O offense instead of a worse version of a typical big ten offense than defenses know how to defend easily
