The story of Memphis’ 2026 defensive staff is already one of unexpected turns and an important reunion. It began with one defensive coordinator and quickly turned to another, and in the process, Charles Huff might have found exactly the voice he needed on that side of the ball.
The Defensive Staff, From Semore to Guidry, and the 2026 Identity
When Huff first assembled his staff, his initial defensive coordinator hire was Jason Semore. Semore fit what Huff wanted on paper, an aggressive coach with a modern approach to defense, and the plan was for him to install a new system in Memphis. But almost as soon as he arrived, Georgia Tech came calling. Semore accepted the Yellow Jackets’ defensive coordinator job, and a buyout clause meant his two weeks in Memphis would cost Georgia Tech and financially benefit the Tigers, even though he never coached a game in blue.
That twist forced Huff to make his first major adjustment as head coach. Rather than scramble, he turned to someone he knew he could trust, hiring Lance Guidry as defensive coordinator and linebackers coach. Guidry and Huff share history from their time together at Marshall, where Guidry’s defenses developed a reputation for attacking fronts, creative pressure, and a relentless mentality. Bringing Guidry to Memphis allowed Huff to build the defense around a philosophy he had already seen win.
Guidry’s system is defined by multiplicity and pressure. He wants a front that can live in different structures, sometimes three down, sometimes four down, and that can slant, stunt, and change the picture without sacrificing gap integrity. His linebackers, the group he coaches directly, have to be coaches on the field, handling checks, fits, and communication. In the secondary, he demands defensive backs who can hold up in man coverage and also execute complex pattern match zones.
To support that approach, Huff and Guidry rely on defensive line coach Eric Mathies and defensive backs coach Dominique Bowman. Mathies is responsible for developing interior linemen and edge players who can both stop the run and affect the quarterback. He must build a rotation that remains effective deep into games. During SpringFest, fans will see his work in how often the defensive line is winning at the line of scrimmage rather than being moved off the ball.
In the back end, Bowman oversees corners, safeties, and nickel defenders who must play with confidence and physicality. In Guidry’s system, corners are often left on islands and asked to compete at the catch point repeatedly. Safeties are heavily involved in both run fits and coverage, reading keys and reacting quickly. Nickel defenders have to be versatile enough to cover slot receivers and support the run. Seven on seven and team periods at SpringFest will be the first public litmus test for how far that group has come.
The defensive staff is supported by analysts and quality control coaches who feed Guidry data on tendencies, formations, and situations. They help shape game plans and install menus for third down, red zone, and backed up defense, allowing Guidry, Mathies, and Bowman to focus more on teaching and less on raw film work.
At SpringFest 2026, the defensive staff’s goal is not to reveal every blitz or exotic coverage. It is to show a unit that looks organized, aggressive, and connected. Fans can watch how quickly the defense lines up between plays, how often they communicate checks, how sound the tackling is in space, and how well the coverage and pass rush work together.
What began with the sudden departure of Jason Semore to Georgia Tech has led to Lance Guidry taking over and reshaping the defense in his image. SpringFest is the first chance for Tiger fans to see that shift, to watch Guidry and his staff in real time, and to begin to understand what a Huff and Guidry defense will be in 2026.
