College football thrives on vicious rivalries. Ohio State vs. Michigan is one of the biggest games of the year, regardless of how highly ranked either team is at the time of play.
There is a little patience involved, of course. For instance, if Auburn doesn't beat Alabama in 2013, Gus Malzahn isn't likely to lose his job. After all, Auburn didn't beat anyone in the SEC last season, so there is an understood curve.
Patience only lasts so long in the bitter rivalries, though. Eventually, you have to beat the one team that matters most. An 0-11 Michigan team can roll into rivalry weekend against an 11-0 Ohio State team, and the coach may get another season just off that one win.
It works the other way around, too. If Ohio State rolled into "The Game" 11-0 and walked out with a loss to an 0-11 Wolverines team, you can bet the coach (yes, even Urban Meyer) would be called into the athletic director's office for a "chat."
One loss won't get you fired, but a three-year skid would certainly get the interview process rolling. There are plenty of coaches that are willing to make a few million dollars to try to succeed where others fail. These coaches have some of the most desirable jobs in the world, at least when they're winning.
Here are 10 of the most intense rivalries in college football. Each and every one can cost a coach his job. It might take some time, but if a coach lets one of these rivalries get to an 0-3 mark, he can expect his seat to start getting warm.
