It's time to breathe out. Every major-college (FBS/former Division I-A) head coaching job is filled.

Well, for the moment. Maybe Brian Kelly changes that in the next few days.

But this is a solid opportunity to look at just how wild instability in head coaching has become. It's easy to see it in the days after a season ends. But in the macro, it's almost as mind-blowing.

Consider:

* In the last year, 30 of the 125 major-college jobs have turned over.

* Kentucky's Mark Stoops, the first hire of the post-2012 season wave, has been on the job longer than 22.8 percent of his fellow FBS coaches. He was hired Nov. 27.

* West Virginia's Dana Holgorsen, promoted in the summer of 2011, has been on the job in Morgantown longer than 54 other head coaches.

* The median hire date of a current FBS coach is Dec. 25, 2010 --- right between Ball State's Pete Lembo (Dec. 19) and Miami (Ohio)'s Dan Treadwell (Dec. 31).

* Southern California's Lane Kiffin, hardly a paragon of a coach who puts down roots, is the 53rd-longest tenured head coach.

* It seems like Jimbo Fisher took over the Florida State job in the very recent past. He's 44th in current tenure.

* Kansas State's Bill Snyder ranks 33rd on the tenure list ... and that only counts his second stint with the Wildcats.

* Northwestern coach Pat Fitzgerald is almost two years shy of his 40th birthday. He still ranks 20th in active tenure at his current gig.

There's all sorts of stuff to sift through in the list below. Of course, the man at the top --- Virginia Tech's Frank Beamer --- comes as no surprise at all.
