Christian Alliegro arrived at Ohio State with a clear opportunity in front of him, and the Buckeyes are counting on him to help solve one of the biggest questions in Matt Patricia’s linebacker room.
The transfer from Wisconsin steps into a defense that needs answers after Arvell Reese left for the NFL, where he was taken No. 5 overall in the NFL Draft. Reese’s departure created a major opening, especially considering the hybrid role he played as both a linebacker and edge rusher. Alliegro isn’t being asked to replace that production by himself, but he does enter Columbus as one of the players most likely to shape how the Buckeyes handle the position this season.
At Wisconsin, Alliegro built a strong enough résumé to make himself one of the more intriguing veteran additions in the portal. In 2025, he earned honorable mention All-Big Ten recognition after finishing with 53 tackles, 34 of them solo, along with eight tackles for loss and four sacks. He put up those numbers despite missing two games because of injury.
His track record goes beyond one season, too. The Connecticut native was a three-star recruit out of high school and has three years of college football under his belt with the Badgers.
Last year, he started eight of the 10 games he played in and had more than four tackles in seven of them. One of his best outings came against Iowa, when he recorded 11 tackles and a pass breakup across 70 snaps.
But the game that really seemed to get Ohio State’s attention came against Ohio State itself. In a 34-0 Buckeyes win, Alliegro still managed six tackles and a season-high two tackles for loss on 67 snaps, and he did it while playing with a broken arm.
Linebackers coach James Laurinaitis said that film from Alliegro against Ohio State and Alabama was enough for him to judge how the transfer would hold up against elite competition. Laurinaitis pointed specifically to the Ohio State game as something that jumped off the tape.
Alliegro described his transfer as a career move, and the early signs suggest it could pay off. He has put himself in position to see plenty of snaps this fall, whether the Buckeyes stick with their usual two-linebacker setup or lean into a three-linebacker package.
That part of the discussion matters because Patricia has more options than Ohio State has traditionally had at linebacker. Payton Pierce is the presumed starter, while Riley Pettijohn and TJ Alford are also fighting for meaningful playing time.
Garrett Johnson and three freshmen are in the mix as well. With that kind of depth, there’s been some talk that Patricia could use three linebackers more often.
Even so, replacing Reese is not going to fall on one player alone. It will take multiple bodies, multiple roles and plenty of rotation.
Still, Alliegro is expected to be right in the middle of it. Early projections have him starting next to Pierce, though he and Pettijohn remain in the race for that job.
If Ohio State goes with a more traditional two-linebacker look, Alliegro would likely line up at Will. He also spent a good amount of spring practice working on the edge and at Sam.
At 6-foot-4 and 245 pounds, he brings a useful blend of size, athleticism and experience to a roster trying to absorb a major loss. His Big Ten background gives him a head start in that transition, and his physical style should fit what Ohio State wants from the position. He has shown he can blitz, play downhill against the run and work through blocks, all traits that matter in a room built around versatility.
The Buckeyes did not bring him in to be a placeholder. They brought him in to make an impact. Whether that comes as a starter or in a heavier rotational role, Alliegro has the tools to become a major piece for a defense that is trying to stay at the top year after year.

Khary Wilder Is Giving Ohio State Fans An Early Reason To Believe
Khary Wilder has already done something in fall camp that tends to get Ohio State fans' attention, shedding his black stripe as a freshman defensive lineman. It is the latest small but meaningful sign that the Buckeyes may have found another young piece for a front that is trying to reload after losing several key players to the NFL Draft, and it comes as the defense prepares for another season with high expectations.
Wilder is the fifth freshman to lose his black stripe this year, and his timing matters because the Buckeyes are expected to lean on depth up front. Under defensive coordinator Matt Patricia, who likes to rotate players, there should be chances for young linemen to earn work, and Wilder now looks like one of the names to watch as Ohio State sorts out its next wave of contributors.

Ryan Day Just Turned Up The Pressure On Ohio State's Bo Jackson
Ryan Day has made it clear that fall camp is not a reward system, and Bo Jackson is being asked to prove his progress the hard way. The Ohio State coach said Jacksons running style looks better than it did a year ago, but he also put the sophomore back on second-team reps early in camp, signaling that development still has to show up in real practice work before it matters on Saturdays.
The message around Jackson is bigger than one depth-chart snapshot. Day wants practice performance to carry into games, and the leash on that growth may not be endless if the results do not keep coming. For a player trying to carve out a larger role, the next stretch of camp will go a long way toward determining how Ohio State views his future. [Read more 🡒]
