If Florida State’s 2024 offense was frustrating, its defense was downright infuriating. The Seminoles stumbled to a 2–10 record in part because of a defense that couldn’t stop the run, couldn’t generate pressure, and couldn’t get off the field on third down. The defensive line — historically one of FSU’s strongest units — became the team’s weakest link.
That reality sparked a complete defensive overhaul for 2025. Players, coaches, and even the scheme have all changed. The hope in Tallahassee is that this isn’t just a patch job — it’s a full rebuild designed to bring pride back to the Florida State defense.
Mike Norvell’s offseason changes started at the top. Longtime DL coach Odell Haggins has moved into an off-field role, while Terrance Knighton now coaches the entire defensive line. John Papuchis slides over to linebackers coach, and defensive coordinator Tony White is installing his signature 3-3-5 defense — complete with the hybrid JACK position, where an edge player can rush or drop into coverage.
This scheme asks for disruptive defensive linemen, athletic linebackers who can fill space, and defensive backs who can blitz or cover interchangeably. It’s an aggressive system designed to dictate play — a sharp contrast to the reactive, coverage-heavy approach of former DC Adam Fuller.
Defensive Line: From Liability to Anchor?
The 2024 defensive line underperformed in every possible metric. For 2025, Florida State has five new players entering the rotation, plus key returners ready to make a leap.
DT Darrell Jackson Jr. (6’6”, 337) might be the most important player on the defense. Norvell has challenged him to play at a level that could make him a Top-10 NFL Draft pick in 2026. Jackson flashed dominance at times in 2024 but needs to deliver consistency — especially in a scheme that leans heavily on a powerful interior presence.
DT Daniel Lyons (6’4”, 292) was one of the few bright spots last season, with 25 tackles and three sacks. The question is whether he’s big enough to anchor inside for long stretches.
DT KJ Sampson (6’3”, 309) had a breakout scrimmage this spring, racking up TFLs and even a big-man interception. His high motor and physical maturity make him a potential surprise star.
Freshman DT Kevin Wynn (6’3”, 343) is the heaviest Seminole in the rotation and could carve out a role immediately as a space-eater.
On the edge, DE James Williams (6’6”, 250) — a transfer from Nebraska — brings leadership and production. He’s a prototype JACK defender: long, fast, and relentless.
DE Jaden Jones (6’5”, 253) returns from a 2024 injury and could be a pass-rush specialist.
Versatile DE Jayson Jenkins (transfer from Tennessee) is expected to play both inside and outside once healthy, while veteran portal additions Deante McCray (Western Kentucky) and Deamontae Diggs (Coastal Carolina) give the group experienced depth.
Linebackers: From Weakness to Potential Strength
The linebackers have been a sore spot for years, but the scheme change makes them even more critical in 2025. The 3-3-5 demands athletic, assignment-sound backers who can play sideline to sideline.
Redshirt senior Stefon Thompson is the on-field general. Having played under White at Syracuse and Nebraska, his system knowledge is invaluable.
Junior Justin Cryer had a strong spring and is emerging as a vocal leader.
Redshirt junior Omar Graham Jr. finished 2024 strong and could thrive in a more aggressive scheme.
Junior Blake Nichelson is one of the most athletic players on defense and will play a big role even if he isn’t starting.
New additions Elijah Herring (Memphis via Tennessee) and Caleb LaVelle (North Carolina) bring depth and competition, though LaVelle missed the spring with an injury.
Defensive Backs: A Rebuild in the Making
FSU loses its best defender from 2024 — Azareye’h Thomas, now with the New York Jets — but still has intriguing pieces. The 3-3-5 means five DBs on the field at all times, and Tony White’s blitz-heavy style should help mask inexperience.
FS Shyheim Brown (6’2”, 205) leads the secondary after starting 11 games last year. He’s back healthy and ready for a big senior year.
SS KJ Kirkland (6’1”, 212) was one of the few players who truly improved in 2024, earning FSU’s freshman defensive player of the year.
At corner, Ja’Bril Rawls (6’1”, 185) is poised for a starting role after a focused spring, while Jeremiah Wilson (5’10”, 185) — the top CB transfer from Houston — brings scheme familiarity from his Syracuse days.
Rover Earl Little Jr. (6’1”, 186) could be a perfect fit for the hybrid role in White’s defense, giving him a chance to bounce back from a tough 2024.
Final Outlook
The 2025 Florida State defense will look drastically different from the 2024 unit that ranked near the bottom of the ACC in nearly every statistical category. Between the coaching changes, the scheme shift, and a wave of new personnel, the Seminoles are betting on a faster, more aggressive identity.
The key will be whether the defensive line — the team’s biggest liability a year ago — can become its strength under Terrance Knighton. If Darrell Jackson Jr. plays to his potential, if James Williams leads a dangerous JACK rotation, and if the linebackers adjust quickly to the demands of the 3-3-5, FSU’s defense could be the surprise turnaround story of the ACC.
For a fanbase still recovering from 2024, even competence on defense would be an improvement. But with the talent influx and Tony White’s aggressive philosophy, the Seminoles are aiming much higher than just “better.”
