So, you want to be a head football coach in college?

You'll get paid well.  But be forewarned...job security in that profession isn't what it used to be.

We live in a "what have you done for me lately" society.  We also live in a microwave society where we want it...and want it now.  The combination of the two has led to so much turnover that it's likely a player who signs to play for an FBS school will be playing for a different coach before his eligibility expires.

An interesting piece by coachingsearch.com shows, of the 129 FBS schools, 63 (48.8%) have been hired in the last three years.  Nearly 83% have been hired since 2011.

Now, not all of these changes were the result of firings.  There were some retirements.  There were many who left one school to take a job at another.  But it doesn't change the fact turnover in the profession is at an all-time high.

Consider this:

Joey Jones of South Alabama is the longest tenured of all schools in the Sun Belt Conference.  His first season was in 2009.  That ranks him 15th in the FBS.  The Jaguars, however, did not play in the SBC for the first few years of their existence.

So...which coach has been coaching in the Sun Belt the longest?

That would be Mark Hudspeth, getting ready to start his seventh season as the head coach of the Louisiana Ragin' Cajuns.  Only 22 coaches have been at their schools longer than Hudspeth.  In fact, Hudspeth is tops in the state of Louisiana as well, when you take both FBS and FCS into consideration.  And, ironically, there are 22 coaches who will make their debuts at their respective schools in 2017.

Hudspeth, of course, has had more success than any other football coach in Cajuns' history with a 48-31 on field record and five appearances in the R+L Carriers New Orleans Bowl in his six seasons.  But the "what have you done for me lately" folks are quick to point out that, although the Cajuns were bowling last season, they've (technically) had two consecutive losing seasons.

And, there will be some who believe this could be a make or break year for Hudspeth (although I am not of that opinion, unless something really unforeseen happens.)

But regardless, the numbers of where we are when it comes to the business of college football should send a message to the next wave of newcomers to head coaching in the FBS.

Enjoy the fat salary.  But keep the phone number of your realtor handy.  Chances are you'll need it sooner rather than later.
