Michigan State engineering prof, student design helmet inserts to help drown out crowd noise for QBs


EAST LANSING, Mich. — The sight was a common one for Andrew Kolpacki. For many a Sunday, he would watch NFL games on TV and see quarterbacks putting their hands on their helmets, desperately trying to hear the play call from the sideline or booth as tens of thousands of fans screamed at the tops of their lungs.

When the NCAA’s playing rules oversight committee this past spring approved the use of coach-to-player helmet communications in games for the 2024 season, Kolpacki, Michigan State’s head football equipment manager, knew the Spartans’ QBs and linebackers were going to have a problem.

“There had to be some sort of solution,” he said.

As it turns out, there was. And it was right across the street.

Kolpacki reached out to Tamara Reid Bush, a mechanical engineering professor who not only heads the school’s Biomechanical Design Research Laboratory but also is a football season ticket-holder.

Kolpacki “showed me some photos and said that other teams had just put duct tape inside the (earhole), and he asked me, ‘Do you think we can do anything better than duct tape,?” Bush said. “And I said, ‘Oh, absolutely.’”

Bush and Rylie DuBois, a sophomore biosystems engineering major and undergraduate research assistant at the lab, set out to produce earhole inserts made from polylactic acid, a bio-based plastic, using a 3D printer. Part of the challenge was accounting for the earhole sizes and shapes that vary depending on helmet style.

Once the season got underway with a Friday night home game against Florida Atlantic on Aug. 30, the helmets of starting quarterback Aidan Chiles and linebacker Jordan Turner were outfitted with the inserts, which helped mitigate crowd noise.

DuBois attended the game, sitting in the student section.

“I felt such a strong sense of accomplishment and pride,” DuBois said. “And I told all my friends around me about how I designed what they were wearing on the field.”

All told, Bush and DuBois have produced around 180 sets of the inserts, a number that grew in part due to the variety of helmet designs and colors that are available to be worn by Spartan players any given Saturday. Plus, the engineering folks have been fine-tuning their design throughout the season.

Dozens of Bowl Subdivision programs are doing something similar. In many cases, they’re getting 3D-printed earhole covers from XO Armor Technologies, which provides on-site, on-demand 3D printing of athletic wearables.

The Auburn, Alabama-based company has donated its version of the earhole covers to the equipment managers of programs ranging from Georgia and Clemson to Boise State and Arizona State in the hope the schools would consider doing business with XO Armor in the future, said Jeff Klosterman, vice president of business development.

XO Armor first was approached by the Houston Texans at the end of last season about creating something to assist quarterback C.J. Stroud in better hearing play calls delivered to his helmet during road games. XO Armor worked on a solution and had completed one when it received another inquiry: Ohio State, which had heard Michigan State was moving forward with helmet inserts, wondered if XO Armor had anything in the works.

“We kind of just did this as a one-off favor to the Texans and honestly didn’t forecast it becoming our viral moment in college football,” Klosterman said. “We’ve now got about 60 teams across college football and the NFL wearing our sound-deadening earhole covers every weekend.”

The rules state that only one player for each team is permitted to be in communication with coaches while on the field. For the Spartans, it’s typically Chiles on offense and Turner on defense. Turner prefers to have an insert in both earholes, but Chiles has asked that the insert be used in only one on his helmet.

Chiles “likes to be able to feel like he has some sort of outward exposure,” Kolpacki said.

Exposure is something the sophomore signal-caller from Long Beach, California, had in away games against Michigan and Oregon this season. Michigan Stadium welcomed 110,000-plus fans for the Oct. 26 matchup between the in-state rivals. And while just under 60,000 packed Autzen Stadium in Eugene, Oregon, for the Ducks’ 31-10 win over Michigan State three weeks earlier, it was plenty loud. “The Big Ten has some pretty impressive venues,” Kolpacki said.

“It can be just deafening,” he said. “That’s what those fans are there for is to create havoc and make it difficult for coaches to get a play call off.”

Something that is a bit easier to handle thanks to Bush and her team. She called the inserts a “win-win-win” for everyone.

“It’s exciting for me to work with athletics and the football team,” she said. “I think it’s really exciting for our students as well to take what they’ve learned and develop and design something and see it being used and executed.”

Potential Michigan football coaching candidate reportedly no longer being pursued

Potential Michigan football coaching candidate reportedly no longer being pursued


On Tuesday, multiple reports began to surface about Washington coach Jedd Fisch no longer being considered by the Wolverines as a candidate for the open head football coaching position at Michigan.

Although it’s still unclear as to why Michigan is seemingly moving off of him as a consideration, college football analyst Josh Pate seemed to confirm the reports on his show that Fisch is unlikely to be a factor in the Wolverines’ search moving forward.

“There’s been some sentiment about Jedd Fisch,” Pate said. “There’s been some though this week—and granted, it’s only Tuesday (at the time of his show). But there’s been some thought this week that Jedd Fisch’s name may be climbing. And that’s because Michigan was taking a hard look at him.

“There’s been some sentiment today that maybe Jedd Fisch’s name has cooled. I think that’s accurate. And I think they’ve done a fairly good job, especially if you’re on The Fort (On3’s The Wolverine) on the message boards over there, I think they’ve done a fairly good job of detailing that. Not necessarily details that I think it’s important for us to dive into—it’s more minutiae based.

“The critical take home points here are—I don’t know that Jedd Fisch is going to be a factor in the Michigan search moving forward. He’s got himself a good job at Washington. It’s one of the better jobs in the Big Ten. In fact, Jedd Fisch may have one of the more underrated jobs in the country. So, it’s not like he needs to be desperate to leave Washington. But I think his name was a factor, I’m not so sure it’s going to be a factor moving forward.”

Fisch’s history at Michigan and where Wolverines go from here

Fisch was considered a quality candidate for the job due to his extensive background in coaching, which includes four different NFL stops and coaching at seven different college programs.

He was the head coach at Arizona from 2021-23 and led a turnaround for the Wildcats under his watch before becoming the head coach of the Huskies in 2024.

In the 2015-16 season, Fisch served as Michigan’s passing game coordinator while also helping with the quarterbacks and wide receivers in his only year with the Wolverines under former head coach Jim Harbaugh.

With Fisch apparently now likely off the board, it looks like the Wolverines will turn to other names of interest.

Arizona State’s Kenny Dillingham and Alabama’s Kalen DeBoer still seem to be the names that are being thrown around the most during Michigan’s search.

During his show, Pate discussed Missouri head coach Eli Drinkwitz as a name that is involved.

Former Michigan defensive coordinator Jesse Minter, who is now in the same role with Harbaugh’s LA Chargers, also seems like a possibility, but the NFL Chargers likely making the playoffs could make things tricky timeline wise to make that happen. Plus, Minter is very likely to be considered for an NFL job in the near future, meaning the Wolverines would likely have to compete against other NFL teams to hire him.

The clock is ticking with the winter transfer portal window beginning on Jan. 2, so whoever Michigan hires, ideally it would be done before that date comes up.

‘Michigan is like an oil field’: Why the coaching search could deliver an elite upgrade despite the chaos

‘Michigan is like an oil field’: Why the coaching search could deliver an elite upgrade despite the chaos


CLEV ELAND, Ohio — The Michigan coaching search has dominated college football headlines this week, creating both uncertainty and opportunity for the defending national champions.

Despite the chaotic nature of the situation, college football analyst Josh Pate makes a compelling case that Michigan will ultimately emerge with a significant upgrade at head coach.

“I think they’re going to end up so much better for this. They’re not in a great place right now, but I mean once the fog clears, like Michigan will have clearly upgraded at their head coaching position,” Pate claims on the latest episode of his podcast, setting an optimistic tone despite the current turmoil.

One of the most significant developments has been Alabama head coach Kalen DeBoer’s definitive statement removing himself from consideration.

“I don’t think Kalen DeBoer is going anywhere. Feel pretty good about our sourcing on that,” Pate said. “You guys are free to believe whatever you want, but I do believe that he’ll be at Alabama this Friday and well beyond this Friday, no matter what the outcome of that game is. I hope I’ve been pretty clear there.”

With DeBoer firmly committed to Alabama, the podcast makes an impassioned case for Arizona State’s Kenny Dillingham as the ideal candidate to revitalize Michigan’s program.

“I think Kenny Dillingham is a wonderful candidate for Michigan. That would be the guy that I would pursue,” Pate said. “I look at that guy and I see what he’s done in terms of quarterback development. I see what he’s done in terms of lighting a fan base on fire. I love the energy. I love the passion. I love how much his guys will go over a cliff for him.”

What makes this endorsement particularly compelling is the podcast’s vivid metaphor about Michigan’s untapped potential and why someone with Dillingham’s energy could be transformational.

“Michigan is like an oil field. I’ve been watching Land Man lately. It’s like an oil field that really hasn’t been drilled properly,” Pate said. “When you do, money is flying all over the place. It’s there. It’s there. I’ve got it on good word. A little birdie has flown in my ear recently and told me, you know, maybe since the Sherrone Moore firing, there’s a little bit of an uptick even in NIL contribution.”

This assessment suggests Michigan’s NIL and donor resources remain largely untapped, creating an opportunity for an energetic, passionate coach like Dillingham to unlock unprecedented support.

Pate notes that despite Michigan’s recent national championship, no one has “really drilled deep at Michigan yet” when it comes to maximizing resources in college football’s new era.

The podcast also addresses the complexity of the search process, noting it’s moving “way differently than the Penn State search” with Michigan employing “search firm stages” that will lead to a search committee.

This methodical approach suggests Michigan is prioritizing making the right hire rather than the fastest hire.

Other candidates mentioned include Lincoln Riley, Eli Drinkwitz and Jedd Fisch, though the podcast clearly positions Dillingham as the transformational choice who could best capitalize on Michigan’s dormant potential.

Interestingly, the podcast draws a distinction between Dillingham and DeBoer’s public statements about being happy at their current jobs: “I don’t think those were the same thing,” hinting that while DeBoer is genuinely staying put, Dillingham might still be in play despite expressing love for Arizona State.

For Michigan fans enduring a turbulent week, the podcast’s perspective offers a compelling reason for optimism.

Despite the messy nature of the coaching change, Michigan appears poised to emerge with a dynamic leader who could elevate the program to even greater heights.
