Indiana's Secondary Faces Its Biggest Test Yet Against Ohio State

Indiana's defense braces for a high-stakes test as they aim to stop Ohio State's unstoppable receiver, Jeremiah Smith, in a crucial conference clash.

Curt Cignetti didn’t need long to make the point.

When asked Monday about Ohio State wide receiver Jeremiah Smith, the Indiana coach reached for the kind of language that usually gets reserved for rarefied talent.

“There’s no one like him right now, playing at this level,” Cignetti said during Monday’s press conference. “He’s a freak. And we’re gonna have to do a great job on him.”

That is the assignment waiting for No. 5 Indiana on Saturday, when the Hoosiers host No.

4 Ohio State at Memorial Stadium. Smith has become the centerpiece of the Buckeyes’ passing game, and Indiana’s secondary will look a lot different than it did in last year’s meetings with him.

Through six games, Smith has piled up 48 catches for 916 yards and 11 touchdowns, averaging 152.7 yards per game and 19.1 yards per catch. He has been even hotter lately, putting up 516 yards and eight scores across his last three outings, including back-to-back 200-yard games against Illinois and Iowa.

The big plays come in bunches. Of his 48 receptions, 23 have gone for at least 15 yards, 10 have reached 25 yards or more, and 39 of them have moved the chains.

Indiana has had some success against him before, though. In the 2024 regular season, Smith managed only three catches for 34 yards against the Hoosiers. He later came back with eight receptions for 144 yards in last season’s Big Ten championship game.

Even with that production in Indianapolis, Indiana still held Ohio State to 10 points in a 13-10 win, and Smith again finished without a touchdown. Repeating that kind of night is going to be harder now, because the personnel around him in the Indiana secondary has changed.

Last season, Indiana leaned heavily on All-American cornerback D’Angelo Ponds in those matchups. Ponds, who also attended Chaminade-Madonna College Preparatory School in South Florida with Smith, is now in the NFL. That has pushed redshirt senior Jamari Sharpe into the spotlight as Indiana’s top corner after starting opposite Ponds a year ago.

Sharpe may have flown a little under the radar nationally, but his production says plenty. He posted an 84.6 Pro Football Focus coverage grade last season, which ranked 17th nationally among qualifying cornerbacks, and added 50 tackles with six pass breakups.

He also had one of the biggest plays in Indiana’s national championship run, intercepting Miami quarterback Carson Beck to clinch the Hoosiers’ victory in January.

Now Sharpe carries even more weight as Indiana’s clear No. 1 corner, and Smith looks like his toughest individual test yet.

The Hoosiers have dealt with injury issues at the position as well, with AJ Harris returning against Nebraska after an extended absence. His comeback gives Indiana another veteran option as it tries to slow an Ohio State passing attack built around Smith.

Indiana’s safety play will matter, too. After the departures of Louis Moore and Devan Boykin, both of whom used up their eligibility after last season’s national championship run, the Hoosiers have turned to Amare Ferrell and Wisconsin transfer Preston Zachman to hold down the back end. Ferrell had four interceptions during Indiana’s 2025 championship season, while Zachman arrived with seven career picks.

That duo gives defensive coordinator Bryant Haines more flexibility with help over the top, and that could be crucial against a receiver who can win deep, stack defenders and make contested grabs.

Ohio State has also been smart about how it uses Smith. The Buckeyes move him around the formation and feed him with deep routes, multiple-move concepts and shorter throws designed to get the ball into his hands.

He has been targeted 67 times in six games, which accounts for about 37% of Ohio State’s passing attempts.

Ryan Day wasn’t exactly subtle when describing the challenge.

“If it’s one-on-one, he’s open. If he’s double covered, he’s sort of open. If he’s triple covered, he’s covered,” Day said.

The comment was playful, but it underscored the Buckeyes’ confidence in Smith’s ability to produce no matter what Indiana throws at him.

Indiana linebacker Isaiah Jones pointed to that same versatility Tuesday.

“Whether it’s a quadruple move down the middle of the field or they’re going to turn him a screen, he can turn it on like that and start getting vertical,” Jones said.

Jones also noted that Smith is dangerous well beyond the downfield shots. Even shorter catches over the middle can turn into explosive plays once he gets rolling.

That puts extra pressure on Indiana’s linebackers and safeties to stay disciplined on intermediate routes while making sure a routine catch does not turn into something much worse.

It also raises the stakes on tackling. Indiana missed 11 tackles against Nebraska, and against a receiver this dangerous after the catch, that kind of slippage can get ugly fast.

Getting to Ohio State quarterback Julian Sayin would help, too. The less time Sayin has to let routes develop, the better Indiana’s chances of avoiding those extended coverage battles Smith thrives in.

“He’s taken it up a notch without question,” Cignetti said. “We’re gonna have to do a great job on him.”

Indiana has already shown it can beat Ohio State without completely erasing Smith. But with the Buckeyes’ star receiver playing at this level and a revamped secondary tasked with handling him, the Hoosiers will need another sharp, disciplined performance Saturday.

Over two career meetings, Smith has totaled 178 receiving yards against Indiana. He still has not scored on the Hoosiers.

Ryan Day Just Framed Indiana's Biggest Edge Against Ohio State

Ohio State coach Ryan Day spent part of his latest session with reporters laying out the challenge ahead in Bloomington, and in doing so he pointed straight at the areas that could matter most for Indiana. He said several injured starters may be back for the Buckeyes, though not all of them will be ready, and he stressed that games like this are often decided by who controls the line of scrimmage. From Indianas perspective, that is no small compliment.

Day also singled out the Hoosiers defensive front and passing game, a reminder that Ohio State is not treating this as just another stop on the schedule. He pointed to the difficulty of playing at Memorial Stadium and said the Buckeyes will need to stay locked in from start to finish, which only adds to the sense that Indiana has given them a matchup worth serious respect.

Indianas Offense Showed Exactly Why This 6-0 Start Feels Different

Indianas 6-0 start has been impressive for plenty of reasons, but the win at Nebraska offered a clearer look at why this team feels different. In a tight road game, the offense found answers when it needed them most, with Josh Hoover managing the game cleanly and delivering 263 yards and two touchdowns without an interception. Up front, Carter Smith helped keep the pocket steady, and the unit as a whole stayed remarkably composed, drawing only one penalty from center Austin Leibfried.

Nick Marsh supplied the kind of late-game burst that can turn a good start into something more, finishing with six catches for 187 yards and two fourth-quarter touchdowns. Indiana has won in different ways already this season, but this one carried a little more weight because it came away from home, in a close finish, and with the offense showing it can stay patient, protect the quarterback and still strike quickly when the moment opens up.

Indiana Defense Proved Something Important In Win Over Nebraska

Indianas win over Nebraska looked nothing like the shootout many expected, and that made it stand out all the more. In a game between teams that had both been averaging more than 40 points per outing, the Hoosiers won 20-17 by leaning into defense, something that has become a genuine point of pride as the season has worn on.

Pro Football Focus grades backed up what the scoreboard already suggested, with Mario Landino, Tobi Osunsanmi and Preston Zachman drawing strong marks for work in the run game, pass rush and coverage. Indiana also asked a lot of outside linebackers Rolijah Hardy and Isaiah Jones, who logged plenty of snaps and were tested often through the air, another sign of how hard Nebraska had to work just to move the ball against this group.
