Ohio State entered the offseason knowing linebacker would become one of the most important questions on the entire roster. Replacing two top-10 picks in Sonny Styles and Arvell Reese was never going to be simple.

Those two were not just productive defenders. They were central to the structure, communication, and athletic ceiling of one of the best defenses in college football.

And for much of the offseason, the uncertainty at linebacker felt real. But after spring practice and the spring game, a clearer picture is beginning to emerge.Ohio State may not have finalized every role inside James Laurinaitis’s room yet, but the Buckeyes now appear to have something increasingly valuable in the modern game. Complementary options with very different skill sets.

Wisconsin transfer Christian Alliegro brings proven Big Ten production and versatility. Payton Pierce offers stability and reliability in the middle of the defense. Riley Pettijohn gives the room its highest athletic ceiling and perhaps its most intriguing long-term upside.

The battle is still ongoing, but the spring revealed something important. Ohio State’s linebacker room looks far more complete than it did when the offseason began. And the way these three players continue developing could quietly determine the ceiling of the entire defense.

Christian Alliegro already looks like a player Ohio State plans to trust

The most important development of the spring in this room may have been how quickly Christian Alliegro appeared to settle into Ohio State’s defense.

When the Buckeyes brought the Wisconsin transfer in through the portal, the need was obvious. Ohio State wanted experience. They wanted communication, they wanted someone who already understood the physical demands and complexity of Big Ten football. Alliegro checked every box immediately.

Across three seasons at Wisconsin, the Connecticut native accumulated 124 tackles, 14 tackles for loss, and eight sacks while building a reputation as a versatile, physical linebacker capable of impacting both the run game and pressure packages.

Last season alone, despite missing time, he still posted four sacks and eight tackles for loss in just ten games.

What stood out during spring practice was not simply the production he brought with him. It was how naturally his skill set appeared to fit inside Ohio State’s defensive structure.

Alliegro consistently worked with the first-team defense throughout spring, and during the spring game, and he looked comfortable directing traffic and operating within the middle of the defense. He played with urgency downhill, communicated well pre-snap, and looked like one of the more assignment sound linebackers on the field.

That matters because linebacker remains one of the most mentally demanding positions in football. Ohio State’s defense asks linebackers to process quickly, fit correctly against the run, handle coverage adjustments, and contribute as pressure players depending on the situation.

Transfers do not always adapt quickly to those responsibilities, but Alliegro largely looked like he already belonged right off the jump.

There is also schematic value in the flexibility he brings. Wisconsin used him in multiple ways throughout his career. He aligned traditionally off-ball, attacked downhill against the run, blitzing effectively, and occasionally operating almost like a stand up edge defender in passing situations.

Ohio State appears interested in preserving some of that versatility rather than locking him into a rigid role.

And realistically, that versatility may become critical. The Buckeyes lost significant production and athleticism with Reese’s departure, particularly in pressure looks and matchup flexibility. Alliegro may not replicate Reese’s exact explosiveness and athletic ability, but he does offer many of the same alignment possibilities within the structure of the defense.

Perhaps most importantly though, he gives Ohio State something it absolutely needed entering 2026, proven experience, and that alone may make him one of the safest bets in the room to play major snaps immediately.

Payton Pierce continues to look like the steady presence Ohio State needs

While Alliegro brings experience from outside the program, Payton Pierce continues to feel like the internal foundation of the linebacker room.

The junior linebacker quietly earned significant trust last season while rotating behind Sonny Styles and Arvell Reese, finishing the year with 43 tackles, 1.5 tackles for loss, an interception, a forced fumble, and a fumble recovery across 14 games.

Even more important than the raw production was the consistency. Whenever Pierce entered the game, Ohio State’s defense remained structurally sound. That trend continued throughout the spring.

Pierce consistently worked with the top units in practice and looked like one of the more dependable defenders during the spring game. He processed quickly, filled downhill decisively, and rarely appeared out of position.

There may not always be dramatic highlight plays attached to his game, but linebackers who consistently keep the defense organized become enormously valuable over the course of a season. And Ohio State clearly trusts the Texas native.

Coming out of high school, Pierce was known more for instincts, football IQ, and physicality than elite testing numbers. That evaluation still fits.

He is not necessarily the most explosive linebacker on the roster, but he may currently be the most reliable. His eyes are disciplined, he takes clean angles, and he understands how to play within the structure of the defense.

In some ways, Pierce profiles as the closest replacement stylistically for some of the stabilizing elements Sonny Styles provided last season, albeit without the same elite frame or athleticism. Not because the players are identical physically, but because Pierce gives Ohio State consistency snap after snap, game after game.

There is also reason to believe his production could increase significantly with expanded usage. Last season, Pierce largely operated in rotational situations behind veteran starters. In 2026, he projects to see a drastic increarse in snaps, particularly in traditional early down linebacker situations where Ohio State needs communication and run-fit discipline.

The spring game only reinforced that trajectory. Pierce looked calm, decisive, and fully in command operating within the middle of the defense, while the coaching staff consistently trusted him with significant reps throughout the entire spring window. That kind of trust is earned, especially at linebacker, where communication, positioning, and reliability can be just as important as athleticism.

Ohio State’s defense is talented enough that it does not need every linebacker to become a superstar or first round draft pick. What it does need is stability in the middle of the field, and Payton Pierce is increasingly looking like the player capable of providing exactly that.

A dependable, assignment sound linebacker who keeps the defense organized snap after snap while allowing the athletes around him to play fast.

Riley Pettijohn still may have the highest ceiling in the entire room

Even with Christian Alliegro’s experience and Payton Pierce’s steady emergence, Riley Pettijohn still remains one of the most important long-term pieces in Ohio State’s linebacker room, even if much of this spring was spent watching rather than participating.

Pettijohn missed a large portion of spring practice while recovering from injury, which limited both his spring game involvement and his ability to fully compete for reps during the offseason window. But internally, that absence does not appear to have changed how highly Ohio State views his upside.

The former high four-star recruit arrived in Columbus as one of the most physically gifted linebackers in his class, and the traits that made him such a coveted prospect are still very obvious.

At around 6-foot-2 and 225 pounds, Pettijohn brings a combination of explosiveness, lateral range, fluid movement skills, and closing speed that few linebackers on the roster, and in the Big Ten, can match. Even during limited action last season, flashes of that athletic ceiling consistently showed up.

In just brief rotational opportunities during the 2025 season, Pettijohn recorded nine tackles, a tackle for loss, a forced fumble, a fumble recovery, and a pass breakup. But the production only tells part of the story.

What stood out more was the way he moved. He looked comfortable operating in space, showed natural pursuit ability sideline-to-sideline, and flashed the kind of burst that allows linebackers to impact both the run game and passing game.

That versatility remains a major reason why Ohio State is so intrigued by his future role within Matt Patricia’s defense.

Rather than viewing Pettijohn strictly as a traditional off-ball linebacker, the Buckeyes appear to see him as a movable chess piece capable of fitting multiple situations. His athletic profile gives Ohio State flexibility to use him as an off-ball linebacker on early downs while also potentially incorporating him into pressure packages, spy assignments, or hybrid alignments against more athletic offenses.

In many ways, Pettijohn’s development could eventually give Ohio State some of the same schematic flexibility it had last season from players like Arvell Reese and Sonny Styles. Modern defenses increasingly value linebackers who can survive in space without sacrificing physicality, and Pettijohn’s high end outcome fits that archetype naturally.

The biggest priority now is simply continued development and availability. Because he missed much of spring practice, Pettijohn still needs valuable live reps within the structure of the defense. Processing speed, communication consistency, and snap-to-snap discipline are often the final hurdles for young linebackers transitioning into major roles at Ohio State, and around the country, and those areas usually improve most through repetition.

Still, even while sidelined, Pettijohn remained a major part of the room’s long-term conversation. Coaches and teammates have continued speaking highly of both his athletic traits and future potential, and there is a strong belief internally that once fully healthy, he can push for a much larger role.

Ohio State already knows what Alliegro brings as an experienced Big Ten defender. It is increasingly learning what Pierce provides as a stabilizing presence in the middle of the defense. Pettijohn, meanwhile, remains the variable with perhaps the highest athletic and overall ceiling of the group.

If his development accelerates once healthy, his role could become much larger than rotational depth or a third linebacker by the end of the season.

The development of this room could determine Ohio State’s defensive ceiling

The encouraging reality for Ohio State is that the linebacker conversation now feels much healthier than it did immediately after the departures of Styles and Reese. Instead of searching desperately for answers, the Buckeyes now appear to have multiple legitimate options with complementary strengths.

Alliegro brings experience, versatility, and proven production. Pierce provides stability, communication, and reliability. Pettijohn gives the room explosiveness and long-term star potential.

Now the challenge becomes building cohesion. Because linebacker remains one of the most important connective positions in football. The linebackers help determine run fits, coverage communication, pressure structure, and the overall stability in the middle of the defense.

When that room functions well, everything around it becomes easier. And after spring practice, there is growing evidence Ohio State may be closer to solving the position than many expected.

The Buckeyes do not necessarily need one linebacker to fully replace Sonny Styles or Arvell Reese individually. What they need is for this room collectively to recreate the versatility, communication, and reliability those players brought to the defense.

If that happens, Ohio State’s linebacker unit may quietly become one of the most important strengths of the entire team entering 2026.
