Indiana football heads into its third season under Coach Curt Cignetti as the defending national champion, but the defense faces significant turnover heading into 2026. The team lost several crucial defenders from Coordinator Bryant Haines' unit, necessitating strong performances from new additions and returning players.

Defensive Line: Replacing Edge Production

Interior Strength Remains Solid

The interior of the defensive line appears strong, anchored by the return of All-American Tyrique Tucker and Mario Landino at defensive tackle. This duo is expected to maintain a powerful, run-stopping core for the Hoosiers.

The Need for Edge Rushers

Conversely, the defensive end position faces a major void after the departure of Mikail Kamara, Stephen Daley, and Kellan Wyatt. These three combined for 34 tackles for loss and 10 sacks during the 2025 campaign.

To address this pass-rushing need, Indiana secured transfers Tobi Osunsanmi and Chiddi Obiazor from Kansas State, along with Joshua Burnham from Notre Dame. Sophomore Daniel Ndukwe might also see increased playing time after showing potential last season. While transfers offer high expectations, uncertainty lingers on the edge compared to the interior stability.

Linebacker Corps: Filling the Void Left by Fisher

Navigating Life After Aiden Fisher

In 2025, Indiana utilized strong depth by frequently playing three linebackers simultaneously, featuring Aiden Fisher, Isaiah Jones, and Rolijah Hardy. That luxury is gone with Fisher moving on to the NFL.

The coaching staff must now determine if senior Kaiden Turner is ready for a substantial role, despite limited prior playing time. Alternatively, they might rely on members of the 2025 recruiting class, such as PJ Nelson or Amari Kamara.

Another option involves reverting to more two-linebacker formations, which could potentially improve pass coverage by adding another defensive back to the field.

Cornerback Room: Aggregating Coverage Strength

No Easy Replacement for an All-American

There is no single player capable of replicating the lockdown coverage provided by All-American D'Angelo Ponds last season. The strategy may shift toward achieving strong coverage through overall depth instead.

Jamari Sharpe returns after making the pivotal interception that sealed the national championship victory. Additionally, Penn State transfer A.J. Harris was recognized as an All-Big Ten player during his sophomore season in 2024.

A key factor for the cornerback unit's success will be whether FCS All-American Carson Williams, transferring from Montana State, can successfully transition to the Big Ten level.

Safety Position: Integrating New and Returning Talent

Pressure on Highly-Ranked Recruit

Amare Ferrell returns, offering versatility as he can cover ground or support the run defense from either safety spot. However, the loss of All-American Louis Moore creates a significant gap in the secondary.

Sophomore Baldwin, who was the ninth-highest ranked recruit in program history according to 247Sports, faces pressure to contribute immediately. He played sparingly as a freshman, recording only five tackles while burning his redshirt by appearing in nine games.

This leaves the void left by Moore for Baldwin or Wisconsin transfer Preston Zachman to fill this season.
