Ohio State football heads into the 2026 season with the talent and recruiting pedigree to contend for a national championship, but Ryan Day’s Buckeyes have legitimate question marks that could determine whether this roster reaches its ceiling. From quarterback Julian Sayin’s development to a completely overhauled linebacker room, Ohio State’s 2026 outlook is one of tremendous upside paired with significant unknowns.

The offensive upside starts and ends with Sayin

The Buckeyes bring back an experienced offensive line, the best wide receiver in college football in Jeremiah Smith, and a young, talented running back group with tremendous upside. The foundation is there for Ohio State to field one of the most prolific offenses in the country.

The biggest question, though, centers on whether quarterback Julian Sayin can take the next step. We saw it down the stretch in 2025: there were moments in the biggest games where the stage seemed too large for the redshirt freshman. Sayin struggled with poor decision-making at the worst possible times. He is a very accurate passer, but he is not the most physically gifted quarterback Ohio State has ever had. The question is whether he can elevate the players around him when things aren’t going the right way.

It’s a possibility that when Sayin’s career is over, we look back on him as a very good college quarterback but still wonder if he was ever going to be the guy who could carry a team to a national title, at least when things aren’t perfect. The overall upside of the 2026 Buckeyes will hinge on just how much growth Sayin shows in Year 2 as a starter.

Defensive line depth behind Kenyatta Jackson remains uncertain

On defense, Ohio State brings back Kenyatta Jackson Jr., who should be one of the better defensive ends in college football after a breakout second half in 2025. Beyond Jackson, though, the defensive line picture gets murky.

The Buckeyes added both John Walker and James Smith through the transfer portal to play defensive tackle. Both should be solid contributors, but the overall ceiling of that duo remains a massive question mark, although I am excited to see the jump that Eddrick Houston could have.

On the opposite edge from Jackson, there is no clear answer for consistent pass-rushing production. Qua Russaw, a transfer from Alabama, is a strong run stopper but has not generated much pressure as a pass rusher during his career. Beau Atkinson, a former transfer from North Carolina, had an underwhelming 2025 season.

Will Ohio State be able to put teams away when opponents know a pass is coming in critical late-game situations? That is a very real concern heading into the fall.

Replacing generational talent at linebacker

Perhaps the most daunting challenge facing the 2026 Buckeyes is overhauling the best linebacker group in the country. Ohio State lost both Sonny Styles and Arvell Reese to the NFL as top-10 picks in the 2026 NFL Draft. Going from two arguably generational talents at the position to an unproven group could represent a major drop-off.

The staff welcomed Christian Alliegro, a transfer from Wisconsin, to help fill some of the roles Reese occupied. Payton Pierce, entering his junior year, should be the starting middle linebacker. There are also promising youngsters like Riley Pettijohn, who is expected to take on an enhanced role with Styles and Reese gone. Ohio State may end up with a good linebacker room. The question is whether “good” will be enough.

This defense has been built around its linebackers making a high volume of plays. Is there a single player in the 2026 group who can replicate that kind of production? That remains a major question, and how Day’s staff answers it could define Ohio State’s season.

What it all means for the Buckeyes

Ohio State has the roster talent to be the best team in college football. The pieces on offense are elite, the secondary should be strong, and the coaching staff continues to replenish through recruiting and the portal. But the gap between a very good season and a national championship often comes down to a handful of positions, and the Buckeyes have legitimate concerns at quarterback, along the defensive line’s edges, and across a rebuilt linebacker corps.

If Sayin takes a step and the defense finds its identity up front, this team has the ceiling to win it all. If those questions linger into October and November, Ohio State could find itself in a tough spot heading toward the College Football Playoff.
