Assistant coach turnover is inevitable in college football.

Sometimes guys leave for bigger and better opportunities, or their head coaches get a new gig and invite them along for the ride.

Other times, they become the fall guy for ineffective performances by players under their watch.

With five weeks remaining in the 2015 regular season, we have a big enough sample size of work to see which SEC coordinators may fall into the latter category.

Here are some coordinators that may be coaching for their jobs down the stretch:

Missouri offensive coordinator Josh Henson

Gary Pinkel has a reputation for being loyal to his people and sticking to his guns in terms of schematic planning. And you really can’t argue with the results, as he’s in the middle of one of the longest coaching tenures in major college football.

But sometimes things get so bad that even the most loyal of people understand that there is a need for a shake up.

That may be where Pinkel is with third-year offensive coordinator Josh Henson.

Though Henson has overseen the Tigers offense during back-to-back trips to the SEC Championship game, Missouri has seen a steady decline in its offensive production since the 2013 season.

The Tigers rank 127th out of 128 FBS programs in scoring offense, generating just 14.9 points per game. Only Miami (Ohio) is worse at 14.4.

Henson’s had to deal with the suspension of starting QB Maty Mauk, injury to RB Russell Hansbrough and a complete turnover of the Tigers receiving corp, so there is plenty reason to say he deserves a chance to make things right.

Still, he has to be feeling the heat after the Tigers managed just three points in a loss to Vanderbilt in Week 8.

South Carolina offensive coordinator G.A. Mangus and co-defensive coordinators Lorenzo Ward and Jon Hoke

The writing was on the wall for all South Carolina coaches after Steve Spurrier resigned, leaving former offensive line coach Shawn Elliott to take over as the Gamecocks’ interim head coach.

South Carolina is almost assuredly going a different direction with the head coaching position at the conclusion of the season, which means most of the Gamecocks current staff will be looking for a new home for the 2016 season.

Expect these coaches to perform much like they are on audition for a new job, which should garner the same uncomfortable feeling that a coordinator under pressure to keep his job would have.

The Gamecocks rank 13th in the league in total defense and 12th in scoring defense, leaving a lot to be desired.

Things aren’t any better for Mangus on the offensive side of the ball, where the Gamecocks are 12th in the SEC in scoring offense and 13th in total offense.

Kentucky defensive coordinator D.J. Eliot

We need to see how this one plays out during the final five weeks, because there is still plenty of the story to be written for the 2015 Kentucky defense.

Now in his third season as the Wildcats defensive coordinator, Eliot is finally coaching with mostly his pick of the lot in terms of players.

That’s works both ways for a coach that had the “rebuilding” excuse for a defense that ranked 13th in the league in points allowed in each of his first two seasons in Lexington.

The Wildcats defense has shown some tangible improvement so far this season, knocking a little more than five points off its season average of points allowed from the first two seasons, but 25.9 points allowed still ranks 11th in the league and is just 3.8 points from the very bottom.

But after two games during which conference opponents have scored 30 more points, Eliot’s seat may start to get warm if the defense collapses down the stretch.

If Kentucky, now 4-3, makes the postseason, things are probably going to be just fine. If not, look out.
