The SEC saw a massive turnover among its coordinator ranks this offseason. Out of the 14 members, seven SEC teams will have a new coordinator, while another added a co-coordinator.

With spring practice wrapped up, we now have a better idea of what kind of changes those coordinators have made.

Auburn
New coordinator: Will Muschamp
Adjustments: On top of bringing energy that his players have said they really enjoy, Muschamp has made some changes to Auburn’s defensive philosophies. He’s already said that he plans to let his star cornerback, Jonathan Jones, play on an island without safety help this year, a departure from Ellis Johnson’s defense. Muschamp has brought his signature juice to the defensive line as well, using multiple fronts, something that was on display as the Tigers registered 6.0 total sacks (5.5 by the defensive line) in the spring game.

Florida
New coordinator: Geoff Collins
Adjustments: Following up a defense constructed by Muschamp is no easy task, but Collins is working to put his stamp on the Gators. Collins runs a more traditional-looking defense than Muschamp, sticking mostly to a 4-3 front. Collins also likes to drop players into coverage and bring pressure from his defensive backs, something Florida didn’t do as much under Muschamp. However, with a strong foundation in place, Collins is keeping much of the philosophy and terminology the same in his first year.

LSU
New coordinator: Kevin Steele
Adjustments: Steele, who comes from a 3-4 defense as linebackers coach at Alabama, will look to give LSU a multiple-front look on defense. LSU will remain a mostly 4-3 team, but will mix in a variety of looks. Steele is also implementing changes to how his linebackers operate while incorporating some more traditional formations. In nickel defenses, LSU will use both strong- and weak-side linebackers, a departure from John Chavis’ defense, while also getting rid of Chavis’ “Mustang” package and replacing it with a traditional dime package, as well as an eight-man front that features four linebackers.

Mississippi State
New coordinator: Manny Diaz
Adjustments: One of the biggest changes Diaz is making is in the Bulldogs’ substitution patterns. No more will there be big groups of substitutions, according to reports out of practice, as Diaz attempts to sort out his depth chart following the loss of a lot of senior talent from last year’s team. Diaz is also known for an aggressive defense, and he’ll bring pressure in unconventional ways this fall. There will be plenty of continuity, though, as the foundation Diaz laid in 2010 remained in place during Collins’ tenure with the Bulldogs.

Missouri
New coordinator: Barry Odom
Adjustments: Replacing Dave Steckel, who had been Mizzou’s coordinator for 14 years, Odom isn’t going to give the defense a complete overhaul. Despite running a 3-4 defense at Memphis, Odom will keep Missouri in a 4-3 base defense. However, Odom, who blended in a variety of looks at Memphis, has left the possibility open that the Tigers will try out three-man lines. The Tigers were just as takeaway-happy in spring ball as they were under Steckel, something that should continue this fall.

South Carolina
New co-coordinator: Jon Hoke
Adjustments: Hoke is set to take over the pass defense side of the equation with Lorenzo Ward maintaining control of run defense. Hoke will also be the new play caller, Spurrier told the media earlier this spring. The biggest changes for which Spurrier is hoping come in the fundamentals department, as he wants the defense to wrap up better when it comes to tackling under Hoke’s tutelage. Hoke is also working to help the Gamecocks disguise their coverages better this year.

Texas A&M
New coordinator: John Chavis
Adjustments: Chavis brings a more aggressive brand of defense to Texas A&M than what the Aggies played under Mark Snyder. The defensive line will be more responsible for generating pressure, with the ends tasked with attacking just one gap. One of Chavis’ staples, the linebackers will play downhill, attacking ball carriers closer to the line of scrimmage than they did in the past. The cornerbacks will also play more press coverage at the line of scrimmage under Chavis after playing farther off receivers in the past.

Vanderbilt
New coordinator: Derek Mason
Adjustments: After his defense failed in his first year on the job, Mason has decided to take over defensive play-calling duties himself. Last year’s defense was complicated, and he will simplify things for the unit this year. Most of the principles will stay the same, but Mason will be counting on development from his core players to help shepherd along improvement on his side of the ball.
