The University of Tennessee’s defense struggled mightily during the 2025 season, leaving the coaching staff with a clear mandate to rebuild before the 2026 campaign.
In a move that sent shockwaves through the SEC, head coach Josh Heupel dismissed defensive coordinator Tim Banks and promoted offensive analyst Jim Knowles to take over the defensive scheme.
A New Defensive Identity
Knowles, known for his work at Michigan State and in the NFL, arrived with a reputation for aggressive, gap‑focused fronts, and he immediately set about reshaping the roster.
The first major addition came from Penn State, where defensive tackle Xavier Gilliam transferred in after a season that yielded 16 tackles, half a sack and a forced fumble.
Gilliam’s physical presence is expected to anchor a line that lost several key contributors, giving the Vols a more imposing front.
At linebacker, Tulane’s Jordan Norman brings a blend of size and pass‑rush ability, having posted 28 tackles and six sacks last year with the Green Wave.
Norman is slated to start at inside linebacker, where his ability to shed blocks and generate pressure should help the Vols improve a run defense that ranked near the bottom of the conference.
In the secondary, Auburn’s Kayin Lee arrives as a cornerback with a knack for making plays on the ball, having recorded 31 tackles, four pass break‑ups and an interception in his final season with the Tigers.
Lee’s experience in the SEC and his ball‑hawking skills are viewed as critical assets as Tennessee seeks to tighten a secondary that gave up too many big plays in 2025.
The infusion of talent from three different conferences illustrates Knowles’ intent to blend proven production with a fresh schematic philosophy, a strategy that could finally translate into the defensive turnaround the program has been chasing.
If the new pieces click, the Vols could see a marked improvement in points allowed and turnover generation, setting the stage for a more competitive SEC schedule in 2026.
