Situations arise when a HC overruling a defensive play call is warranted, even if it fits the definition of micromanaging.
I don't recall the exact details, but I believe there was a Miami game during CPJ's tenure where they kept running the same play (swing pass to boundary, maybe?) successfully over and over while we wanted the clock to run out. It may have been Roof calling the defense, but eventually, CPJ got fed up and told him to stop that and do something else. He mentioned it in his presser afterwards.
Edit to add: Pretty sure it was Roof's "bend don't break" style that was killing us on that drive.
