It takes more than one game for a coach to stave off the hot seat; in most cases, after all, only long-term disappointment can land a coach there in the first place, so why should one minuscule victory set him free?
Having said that, one ill-timed loss can turn a hot-seat coach into a dead man walking or—if the situation calls for it—a now-former coach right there on the spot. (For more information, see: Kiffin, Lane.)
No job is ever "safe" in college football, but of the 65 head coaches in major conferences (plus Brian Kelly at Notre Dame), 10 stick out with hotter seats than others. That doesn't mean they are the only ones who can be forced out—Frank Beamer at Virginia Tech, for example, might suffer the same fate as Mack Brown after another bad season—but they are the ones who must tread the most carefully and whose teams must make the most improvement.
And in each case, there is a game (or games) they can't afford to lose.
Let's take a closer look.
Note: For the sake of being germane to the highest number of readers, only coaches from the five power conferences were included. I haven't forgotten about you, Ron Turner and Norm Chow.
