I'll bet your vice principal could teach classes, and used to teach classes before being promoted. They may even do so occasionally, if a teacher is unexpectedly sick. My school's vice principal taught two class, so about 4 hours a week IIRC. I'll also bet that's unlikely to be the case for the football coach.
