Texas A\&M’s defensive line faces key departures, leaving gaps in depth and experience that must be addressed before the season.

As the Texas A&M Aggies prepare for the 2025 college football season, one of the most pressing concerns within the program lies in the defensive line—a unit that, for much of the last decade, has been a source of identity and strength. With the departure of multiple key contributors and a coaching transition under head coach Mike Elko, the Aggies now face the challenge of rebuilding a defensive front that must uphold the aggressive, physical standard expected in the SEC.

The defensive line is often referred to as the heartbeat of any great defense, and in the SEC, it’s especially critical. Winning at the line of scrimmage is not a luxury—it’s a requirement. For a team like Texas A&M, which is looking to regain its competitive footing, plugging the gaps on the defensive front will be essential to both defensive cohesion and the broader success of the team.

Let’s break down where things stand, who is gone, who remains, who might step up, and what this all means for the Aggies’ 2025 campaign.

The Departures: Massive Shoes to Fill

Texas A&M’s offseason was defined by coaching changes and player movement, and few position groups were affected more than the defensive line. Several key veterans either graduated, declared for the NFL Draft, or transferred to other programs.

Notable losses include:

• McKinnley Jackson (DT): A reliable interior anchor who started over 30 games for the Aggies. Jackson’s combination of strength, discipline, and leadership made him the centerpiece of the defensive line for the past three seasons.
• Fadil Diggs (DE): An edge rusher with high upside who led the team in sacks during his junior year. His departure to the NFL leaves a significant void in pass rush production.
• Isaiah Raikes (DT): A rotational defensive tackle who logged significant snaps and provided depth on early downs.
• Shemar Turner (DE): A late transfer portal surprise, Turner was expected to be a cornerstone in the pass rush rotation. His departure exacerbated concerns about edge depth.

These players weren’t just contributors—they were leaders in the locker room, reliable presences on game day, and veterans who knew how to compete in the SEC trenches. Their absence leaves both physical gaps and experience deficits that can’t easily be replaced.

Who’s Returning: The New Core

Despite the exodus, Texas A&M isn’t devoid of talent. Several returning players now have an opportunity to step into larger roles and establish themselves as starters.

Key returners:

• Walter Nolen (DT): A former five-star recruit and one of the top players in the 2022 recruiting class. Nolen has flashed dominance in spurts but has yet to put together a fully consistent campaign. With Jackson gone, Nolen becomes the centerpiece of the interior defensive line. His size and explosiveness could make him a breakout star if he maintains health and stamina.
• Albert Regis (DT): A high-motor interior lineman who showed improvement as a rotational player last season. Regis brings experience and could rotate alongside or behind Nolen to keep the middle fortified.
• Enai White (EDGE): Another highly touted recruit who has shown glimpses of his potential. White is expected to compete for a starting role on the outside and will need to generate consistent pressure to replace what was lost with Diggs and Turner.
• Gabriel Brownlow-Dindy (DL): One of the most versatile linemen on the roster. Brownlow-Dindy has the ability to play multiple positions across the front and will be a key asset as the Aggies adjust their fronts and formations under Elko’s defensive scheme.

Incoming Help: Freshmen and Transfers

To address immediate depth concerns, Texas A&M has turned to both the recruiting trail and the transfer portal. While expecting true freshmen to dominate in the SEC trenches is a tall order, some newcomers could make a difference.

Freshmen to Watch:

• Elijah Rushing (DE): A lengthy and athletic edge rusher, Rushing was a top-100 national prospect who brings energy and raw pass-rushing talent. He may need a year of development before taking on full-time snaps, but he’ll likely see situational use early on.
• Davion Carter (DT): A powerful interior presence who has drawn comparisons to a young McKinnley Jackson. Carter is physical but raw, and will need time to adjust to SEC speed and technique.

Transfer Additions:

• Julius Coates (EDGE – Arkansas): A senior transfer with SEC experience. Coates provides veteran leadership and depth and could be an immediate rotational piece.
• Isaiah Iton (DT – Ole Miss): Iton brings size and maturity to the defensive interior. While not a star, his experience in the conference makes him a dependable option during early downs.

Scheme Shift Under Elko

With Mike Elko returning as head coach, there’s a renewed emphasis on defense—and specifically, the importance of line play. Under former head coach Jimbo Fisher, the defensive line was often tasked with playing gap-control and traditional 4-3 principles. Elko’s philosophy leans more toward multiple-front defenses, aggressive stunts, and exotic blitz packages.

That means defensive linemen will be expected to do more than occupy blockers—they’ll need to disrupt, penetrate, and set edges. For players like Nolen and Brownlow-Dindy, this could unlock their potential, as they’ll have more freedom to attack upfield.

However, it also means that discipline and communication will be crucial. Younger players or recent transfers will need to quickly absorb the system and build cohesion. Mistakes in gap assignments or timing can lead to big plays in the SEC, where every inch matters.

Depth Concerns and Health Risks

One of the more glaring issues ESPN and other analysts have flagged is depth. Texas A&M has top-tier starters at key positions, but behind them, the drop-off is sharp—especially on the edge.

This lack of depth becomes even more dangerous when factoring in the physical toll of an SEC schedule. By midseason, most teams are dealing with injuries, and the Aggies can ill afford to be thin in the trenches. If players like Nolen or White miss time, Texas A&M could find itself scrambling to field SEC-caliber lineups.

Conditioning and injury prevention will be a key focus in fall camp. Expect Elko’s staff to use the early non-conference games as a testbed for rotations and stamina—trying to identify who can contribute meaningful snaps in October and November when the competition intensifies.

The Bigger Picture: Why It Matters

Texas A&M’s defensive identity will be tested early and often. The SEC is full of elite offenses—LSU, Georgia, and Alabama all feature top-tier offensive lines and NFL-caliber backs. The Aggies’ ability to slow down the run, pressure quarterbacks, and control the line of scrimmage will likely determine the outcomes of several critical matchups.

While the linebacker and secondary groups have talent, no defensive unit can function at full capacity if the line can’t create disruption. Last season, the Aggies were inconsistent—dominant in some matchups, invisible in others. Elko is determined to bring stability and toughness to that group.

If Texas A&M can build even a top-three defensive line in the SEC, it could shift the entire defensive equation—creating more turnovers, shorter third downs, and better field position. But if the Aggies struggle to fill the holes left by their veterans, opposing offenses may exploit mismatches at the line all season long.

A Position in Transition

The Texas A&M defensive line enters 2025 with immense potential—but even more pressure. This group is talented, young in places, and adjusting to a new system. ESPN and other analysts have identified it as the biggest wild card in the Aggies’ pursuit of SEC contention.

Can returning stars like Walter Nolen and Gabriel Brownlow-Dindy take the leap? Will transfer veterans provide steady leadership? Can freshmen like Elijah Rushing contribute early? And most importantly, can this group stay healthy and grow into a unified front?

If the answer is yes, Texas A&M’s defense could emerge as one of the most formidable in the conference. If not, the Aggies may once again find themselves in the frustrating middle tier of the SEC—loaded with talent, but unable to deliver results where it matters most: in the trenches.
