Illinois will head into the 2026 season leaning on players it has spent years developing, and that’s especially true on defense and up front. After losing Luke Altmyer and several other key contributors from the 2025 team, the Illini are counting on a few familiar names to step into bigger jobs and keep the roster moving in the right direction.
One of the most important of those pieces is James Kreutz, who is expected to take over the “Mike” linebacker spot after spending the last few seasons behind three-time All-Big Ten honoree Dylan Rosiek. Kreutz has already logged meaningful snaps, starting five games over the past two seasons, including four as a sophomore in 2024.
In that span, he has piled up 84 tackles, 4.0 tackles for loss and four pass breakups. Illinois will ask him to be the central figure in the second level of the defense, and his reputation as a smart, reliable tackler suggests he’s built for the jump.
That role only becomes more important with Bobby Hauck taking over as defensive coordinator.
The offensive line has its own set of moving parts, and Nathan Knapik is one of the names to watch there. Illinois’ veteran starters limited the reserves’ chances to crack the rotation in 2025, but Knapik got a real look when J.C.
Davis opted out of the Music City Bowl. In that lone start, he protected Luke Altmyer’s blind side and made a strong case for a larger role.
The picture changed when Illinois added Colorado State transfer Christian Martin, who started all 12 games at left tackle for the Rams last season. That could push Knapik to the right side, while JUCO transfer TJ Taylor also enters the mix for Melvin Priestly’s old spot.
Even so, Knapik’s size and experience should keep him in the conversation for plenty of snaps. He is listed at 6-foot-7 and 300 pounds.
On the edge, Joe Barna looks like the next man up after former Illinois standout Gabe Jacas moved on to the New England Patriots. Barna, who has drawn comparisons to Jacas, is listed at 6-foot-4 and 265 pounds.
In two seasons of limited action, he has already produced 3.5 sacks, a forced fumble and two pass breakups. Barna said of the new staff, “I'm super excited to have this new staff here...
It's going to be aggressive, we're going to go fast... I feel like there's a lot more plays to be made, and a lot more times I'll be in the backfield.”
That aggressiveness should suit him, but his biggest job may come against the run, where setting the edge will be critical if Hauck’s defense is going to stay sturdy against strong rushing attacks.

Illinois Adds Trezavant Boyd As 2027 Secondary Build Keeps Growing
Illinois 2027 secondary build picked up another piece with the addition of Trezavant Boyd, a three-star cornerback from Miami Central who brings a profile that fits the kind of long-term defensive planning programs chase on the recruiting trail. Boyd is rated by 247Sports as the 72nd-best cornerback nationally and the 61st player in Florida, and his physical tools and playing style give Illinois another prospect to mold for the back end of its defense.
The appeal here is less about immediate impact and more about how Boyd could grow into the system over time. He may need a couple of years before hes ready for steady defensive snaps, but his frame and movement skills point to a player who can be developed into a useful piece in Illinois scheme, with early value possibly coming in other phases while he learns the college game.

Illinois Finally Rewards Josh Whitman For Changing Everything
Josh Whitmans run as Illinois athletic director has now been rewarded with the kind of long-term commitment that usually follows real change, not just promises of it. Since arriving in 2016, the Illinois alum and former football player has helped reshape the department from the top down, and the school has clearly decided the results across its biggest programs are worth locking in for the long haul.
The extension keeps Whitman in place through 2036, with his pay set to climb over time as Illinois bets on continuity after years of progress in football and basketball. Bret Bielema, Brad Underwood and Shauna Green have all become central to that turnaround, and the broader picture around the department is hard to ignore: bowl seasons on the gridiron, a Final Four in mens hoops, and steady NCAA Tournament work from the womens team.
