Bret Bielema won't name a defensive play caller.
The Illinois football team will face Purdue in Week 5 following a blowout loss to Ohio State. Bret Bielema will not say who is calling the defense.
Defensive coordinator Bobby Hauck abruptly left the program after just four games on staff. The Illini have a plan in place for the immediate future, but their head coach won’t dish on the details.
Instead, Bielema is choosing to keep things under wraps. He will not make defensive players or coaches available to the public this week. It’s created questions surrounding staff duties ahead of a Big 10 showdown.
Bobby Hauck didn’t like college football.
More specifically, he didn’t enjoy the current landscape of the sport.
Hauck retired from his post as Montana head coach last offseason after eight years at the helm. That came after a previous seven-year run leading the Griz between 2003-2009.
He cited the “transient nature” of NCAA athletics in his reasoning for leaving. He didn’t like the new age of NIL and the transfer portal.

“I kind of got tired of all that, dealing with agents and the transient nature of it,” he said after announcing his retirement last February. The game became transactional. There was no loyalty.
Hauck is the Big Sky Conference’s all-time winningest coach. He was 151-43 with the Griz, making four national championship games and winning eight league titles.
The transfer portal created an unexpected problem not experienced in his first stint with the program. Success brought interest from outsiders. His roster was constantly ravaged by vultures. Montana’s top players bailed after the 2025 season to find new homes.
Hauck’s retirement was short-lived, however. He was hired by Illinois as defensive coordinator a week after leaving the Griz. His stint in Champaign, too, will be brief.
Illinois football has no defensive coordinator.
Hauck and Bielema mutually agreed to part ways after Week 4. The head coach says his assistant actually approached him about the move.

“He said, it’s not working for me.”
“I asked him if he had suggestions. After he said… I knew that it was at a point where it wasn’t going to be any good to stay with him in that capacity & do that role.”

Hauck’s tenure at Illinois lasted four games. The defense allowed 73 points in their only two matchups vs. Power 4 competition.
The Illini had no answers for Ohio State last Saturday. The Buckeyes racked up 518 yards of total offense. Jeremiah Smith caught four touchdowns. After the loss, Hauck said, “It’s not working for me.”
Bret Bielema addressed the media on Monday to preview the team’s matchup with Purdue. He was asked about play calling duties moving forward. He refused to provide any intel.
“We have a succession plan in place,” Bielema said before getting tight-lipped. “I’m going to put the defense on lockdown. No coach or player is going to talk until Saturday after the game.”
When pressed on the play calling duties, he remained mum.
“Push rewind, 30 seconds, and you’ll get your answer,” he replied. “We’re going to do what we do this week in the building and on the practice field. Saturday, you’ll see the answer to what we put in place.”
No one outside of the Illinois locker room knows who will call the defense on Saturday against Purdue. Bielema ensures there is a plan in place, which will be unveiled at kickoff.
He believes it’s the best course of action. Until then, we’ll have more questions than answers on the staff and future.
