Iowa’s defense is walking into next season with more uncertainty than it’s used to, and Zach Lutmer looks like the player who can keep the whole thing from wobbling.
The Hawkeyes are replacing all four starters on the defensive line, and the secondary has its own rebuild to manage after losing starting safety Xavier Nwankpa, corner TJ Hall to graduation, and rising star Koen Entringer to transfer. That’s a lot of turnover for a unit that usually prides itself on being steady and familiar. Lutmer, though, gives Phil Parker a piece that can be plugged in just about anywhere.
He’s already shown he can do damage all over the back end. Last season, Lutmer posted 71 total tackles, seven pass breakups and three interceptions while lining up at cornerback, safety and the CASH position. That kind of flexibility matters even more now, because Iowa is expected to lean on him heavily as the defense sorts out its new look.
What really sets Lutmer apart is what happens before the snap. At Big Ten Football Media Days, he made it clear that his game is as much about the mind as the hits.
Asked about how he processes the game, Lutmer described the way he stores and replays plays in his head: "Plays like that just come in my head, and it's on repeat. They've beat us on this play before.
We have to remember that play and stick it in a file, pull it out at the right time."
He was one of three Hawkeyes at the event, joined by Addison Ostrenga and Jayden Montgomery, and the conversation quickly turned to the way he sees the field. Lutmer said he likes getting inside opponents’ heads, even to the point of tossing out random comments to throw off the offense. He also came off like someone with a rare memory for what he’s seen before.
Tim Lester pointed to a spring moment that said plenty about Lutmer’s feel for the game. Lester had installed a play the offense hadn’t used since the fall, and Lutmer still called it out correctly.
Lester was surprised, and impressed, that he remembered it. Lutmer said players often assume he’s digging through the offensive playbook, but that’s not the case.
He’s simply filing away the plays that have already worked against Iowa and waiting for the next time they show up.
That kind of recognition is exactly why the Hawkeyes will need him to be more than just productive. With so many new faces around him, Lutmer’s ability to diagnose plays and get the secondary lined up correctly could end up being one of the biggest reasons the defense holds together.
There’s also a real chance his name starts showing up in award chatter. With a breakout 2025 season behind him, Lutmer could find himself on the Jim Thorpe Award watch list when it is released on August 12. The award goes to the best defensive back in college football, and after the season he just had, he belongs in that early conversation.
Last year’s finalists were Mansoor Delane of LSU, Leonard Moore of Notre Dame and Caleb Downs of Ohio State, with Downs winning it. Downs had 68 total tackles, two interceptions and a pass breakup, which still came up short of Lutmer’s numbers. If Lutmer takes another step, the Thorpe talk could get loud fast, and so could the speculation about him heading to the NFL early.
For Iowa, though, the immediate issue is simpler: keep Lutmer healthy, keep him on the field and let him do what he does best. If he’s out there, the defense has a chance to steady itself. If he’s not, the margin for error gets a lot smaller.

Tavion Banks Just Put Iowas Frontcourt Situation Back In Play
A Colorado federal judges ruling this week has opened the door for a new round of roster math across college basketball, and Iowa is already feeling the ripple effects in its frontcourt. The injunction requires the NCAA to grant an extra year of eligibility to players from the 2022 high school class who finished their eligibility in the 2025-26 season, which puts Tavion Banks in position to come back for one more year after what had seemed like the end of his college run.
Banks has shown appreciation for Iowa and coach Ben McCollum, but his future now sits in a more complicated place than it did a few days ago. His recruitment is open, and the ruling has effectively put his next move back on the table, leaving the Hawkeyes with another roster decision to monitor as the offseason unfolds. [Read more 🡒]
Iowa Still Has One Linebacker Battle Fans Cannot Ignore
One of Iowas quiet offseason questions still carries plenty of weight heading toward the 2026 season: who lines up next to Jayden Montgomery at linebacker? Montgomery looks set for a starting role, but the Hawkeyes are still sorting out the other spot, and that competition has the feel of something that could shape how the defense comes together once camp gets going.
Cam Buffington has put himself in the conversation with a strong spring, while Preston Ries, Landyn Van Kekerix and Derek Weisskopf remain viable options as the picture develops. Montgomery has also made clear this could be more fluid than a simple two-man race, with multiple players potentially seeing the field depending on the defensive scheme and other factors, which leaves Iowa with a decision that may not be fully settled anytime soon.

Curt Cignetti Just Framed Iowas 2025 Season In A Painful Way
Curt Cignetti did Iowa a favor and a disservice at the same time when he called the Hawkeyes one of the most underrated teams in the country last season. It was a compliment rooted in reality, because Iowa finished 9-4, picked up major individual recognition with Logan Jones making the All-Big Ten first team, and saw its offensive line take home the Joe Moore Award. It was also a reminder that this program spent much of the year living on the edge, with close losses to ranked opponents and the kind of uneven injury luck that can tilt a season.
Mark Gronowskis injury loomed over that run, and it is part of why the conversation around Iowa now feels a little uneasy despite the hardware and respect that came in 2025. The Hawkeyes head into 2026 with only 10 returning starters and a schedule that offers little margin for error, which makes Cignettis framing sting a bit more than it should. Iowa was better than many people realized last fall, but repeating that formula may be a much tougher ask. [Read more 🡒]
