“Heart and Soul”: Michael Kilbane’s Impactful Return to NU’s Defensive Line

It took just nine defensive plays in Northwestern’s Week 3 game against Colorado for a massive momentum swing.

Then, in his season debut, fourth-year defensive lineman Michael Kilbane forced a fumble that fifth-year defensive back Robert Fitzgerald recovered, marking the first of four turnovers forced in a dominant 41-7 win over the Buffaloes. 

“I felt like I got good knockback on the tight end, and I saw the running back cutting away, so I was trying to make a play, help out our team,” Kilbane said. “I took a chance, took a shot at the ball. At that point, it was a pretty tight game, and I knew that a forced fumble is something that Coach McGarigle emphasizes all the time. That’s something I tried to do, and I executed. I’m happy it bounced our way.”

Kilbane finished the contest with six tackles, one tackle for loss and one forced fumble, becoming the first Northwestern defensive lineman to record those numbers in a game since Adetomiwa Adebawore did so against Duke on Sept. 10, 2022.

After his Week 3 performance, Kilbane earned a spot on PFF’s National Team of the Week, posting a 91.9 PFF grade. He is PFF’s highest-graded defensive lineman this season with at least 20 snaps, and his 92.4 run defense grade leads all eligible FBS defensive linemen.

To fifth-year linebacker and team captain Braydon Brus, Kilbane represents an irreplaceable part of the Wildcat defense.

“He’s the heart and soul of our defensive line,” Brus said. “It’s just exciting knowing you have such a playmaker down there.”

Kilbane is coming off a 2025 season in which he set career highs in tackles (43), tackles for loss (7.5) and sacks (3.5), all of which lead the returners of the Northwestern defensive line room.

A Wildcat through and through, Kilbane has spent four years working to develop as the “heart and soul” of the Northwestern front four. 

In 2023, Kilbane led all Wildcat first-years in snaps with 146, playing a rotational role off the edge in the latter half of the season. Then, during the 2024 campaign, Kilbane began playing more snaps on the interior of the defensive line before returning to a primary edge role last season in 2025.

Kilbane credited role models on the defensive line such as Aidan Hubbard — who ranks fifth in program history in career sacks (20.5) — Carmine Bastone and Sean McLaughlin for helping him grow on the field and as a leader off the field.

Defensive Line Coach Ross Kolodziej said that Kilbane has taken the “bull by the horns” to lead the younger players on the Wildcat defensive line. For Kilbane, it’s a full-circle moment from just a few years ago when he was learning from Hubbard, Bastone and McLaughlin.

“I was just listening to each of them and did what they did,” Kilbane said. “I would watch them work every day, and I would feel inspired by them, not only to be a leader, but a really good worker. I feel like I try not only to be a vocal leader but also try to work hard every day because I know that there’s going to be a young guy who might see me work hard and be like, ‘That’s how I get to the top.’”

Since Kolodziej joined the Northwestern coaching staff in January 2026, he has seen Kilbane continuously grow as a player. Kilbane attributed some of the growth he showed against Colorado to Kolodziej, who helped him identify weaknesses in his game and areas he could emphasize more.

After coaching several future NFL players in his previous stops at Stanford, Wisconsin and Pittsburgh, Kolodziej has a feeling that Kilbane may just be next in line to reach the pros.

“Greatness is just being consistently good, and that’s what he’s been a hallmark of here — looking to get 1% better every week,” Kolodziej said. “His talent’s up there with all the draft picks I’ve had. He’s All-Big Ten caliber, definitely a guy that’s going to be wrecking shop on Sundays.”
