College Football Defensive Players Who Will Break Out in 2026

The annual offseason roster churn in college football sends top performers to the next level, but those departures also create opportunity.

Vacated snaps must be filled, and there is never a shortage of players aiming to inherit them. Some veterans are looking at their final shot to contribute, while many transfers and young players are angling for their first chance.

In the right situation, a true breakout season can happen, too.

The following players are simply personal picks, although the main factors are perceived talent, projected role, and, where possible, recent production.

Bryce Deas, LB, Auburn

Auburn returns top tackler Xavier Atkins in the middle of the defense, but the rest of the linebacker group has playing time available.

Bryce Deas is a strong candidate for that action.

Not only did Robert Woodyard Jr. transfer out, but Deas steadily earned more snaps late in 2025 anyway. The true freshman ended his debut season with 12 tackles, registering a pair of stops for loss and pass breakups.

One particularly intriguing part of Deas' outlook is his versatile skill set. In those limited snaps, he aligned all over the field and caused chaos as a blitzer.

Demarcus Riddick will be a factor in the rotation, but Auburn coaches may find it difficult to keep Deas off the field.

Daniel Ndukwe, Edge, Indiana

On the heels of winning a first-ever national championship, Indiana must revamp its edge-rushing group in 2026.

Gone are Stephen Daley, Mikail Kamara, and Kellan Wyatt, who combined to produce 34 tackles for loss. All three used up their college eligibility and leave significant holes up front for the Hoosiers.

Due to injuries, though, Daniel Ndukwe already has a slight head start.

Wyat missed the latter half of the campaign, and a freak injury sidelined Daley down the stretch. Ndukwe absorbed a rotational role, and he provided seven tackles with two sacks and a forced fumble in three College Football Playoff games.

Ndukwe needs to stave off strong competition from incoming transfers, but he has a clear opportunity to become a key IU defender.

Kobie McKinzie, LB, Northwestern

Had he returned to Oklahoma, Kobie McKinzie would've presumably been a top player on the SEC defense.

Instead, he'll be leading the unit at Northwestern.

McKinzie isn't a prototypical breakout option, given that he notched 30-plus tackles in each of the last two seasons. However, even as a half-time starter, McKinzie never played a majority of snaps for OU.

That opportunity is wide open at Northwestern, which has to replace 100-tackle linebacker Mac Uihlein. McKinzie's potential is enormous.

Ira Singleton, Edge, SMU

SMU quickly asserted itself as a threat in the ACC, and efficient use of the portal is crucial for the Mustangs to sustain that level.

Among others in 2026, they're counting on Ira Singleton to continue the trend. SMU brought him in from South Florida, where the edge-rusher recorded 17 stops with three for loss, six hurries, and a fumble recovery last season.

Singleton's upside is very appealing, though.

That production doesn't look impressive on paper, but flip on a replay of USF, and you'll notice the 6'5", 240-pounder being a nuisance. The official stats do not accurately capture how often Singleton disrupted the QB.

Now on a larger stage at SMU in a power conference, Singleton has a path to demand more national recognition.

Chaz Coleman, Edge, Tennessee

As for Chaz Coleman, it's all about playing time.

The recent top recruit held a reserve role as a true freshman at Penn State. Despite his limited role, Coleman had eight tackles (three for loss), recovered two fumbles, and picked up some peripheral numbers.

Penn State's implosion ended up nudging him into the portal, and Tennessee—which also hired PSU coordinator Jim Knowles—soon added Coleman.

Considering how much production the Vols must replace up front, they not only are expecting a big season from Coleman but need it, too.

Don't be surprised if he puts together an All-SEC year in his UT debut.

Lance Jackson, Edge, Texas

Despite a significant pair of pass-rush departures, Texas is still in a great position for 2026. The main reason is the return of Colin Simmons, who's accumulated 29.5 tackles for loss and 21 sacks in two college seasons.

Having a disruptor of his caliber is terrific, of course, and not in the least because of how it can help a young player.

As opposing blockers focus on slowing Simmons, Lance Jackson should face favorable matchups. He immediately held a backup job as a true freshman and closed the 2025 season with 16 tackles (two sacks).

Jackson won't be the featured player, but he could be a very effective one.

Mateen Ibirogba, DT, Texas Tech

Although he was a coveted transfer this offseason, Mateen Ibirogba is not a proven defender at the FBS level.

Last year at Wake Forest, the former Georgetown standout made 21 tackles with a modest 3.5 for loss (two sacks). However, three teammates on the interior line logged more snaps than Ibirogba.

Yet that doesn't mean he wasn't noticeable.

Ibirogba certainly grabbed the attention of Texas Tech, an active team in the portal and a defense in need of reinforcements up front. And, conversely, the Red Raiders were an appealing spot because of how transfer D-tackles A.J. Holmes Jr. and Lee Hunter performed so well in 2025.

If this vision plays out as hoped, Ibirogba will be a breakout piece for a program set to chase a second straight Big 12 crown.
