What is the one thing that all 124 FBS college football head coaches have in common?
Though the answer to this provocative question could be as varied as sleep deprivation, increased levels of seasonal stress or bouts with job insecurity, I would argue that an even truer commonality is regret.
Indeed, whether a gridiron leader is 11-2, 2-11, 12-0, 0-12, 3-6, 6-3 or somewhere in between each and every college head football coach must live with some level of regret.
And whether the source of this remorse is due to an individual game, a play, an ideological approach or even one player, there is something that eats at him and that something happened as recently as the 2012 football season.
The following slideshow utilizes the AP Top 25 released just this past Sunday and highlights the biggest regret each ranked coach has after 12 weeks jam-packed with action.
We count the lamentations down from No. 25 all the way to No.1 and in doing so we establish a strong case that the life of a college football coach, though glorious in possibility and lofty in nature, is no picnic.
