Set two conditions. One is for what would mean an automatic firing for Mullen this season, the other for what would mean an automatic retention (no way would you fire him, but not necessarily a contract extension). It can be record, result against a certain team or set of teams, or attire choice. It's up to you. We'll assume if the keeping condition is met, he stays even if the firing condition is met. I'll go with.
Automatic Firing - 2-10 or worse
Automatic Staying - Beat Bama and Ole Miss
