Luke Fickell identifies two lesser-known breakout players to watch on Wisconsin Badgers defense

In this story:
The Wisconsin Badgers defense has a few key leaders it knows it can rely on.
Luke Fickell has his eyes on a few lesser-known starters who could break out in 2025.
A lot of the attention will go to play-makers like safety Preston Zachman and cornerback Ricardo Hallman, who will be critical to the team's success this season.
But Fickell was asked on the Cover 3 podcast about which other players he thinks will step up this season, and he identified two.
One is senior Austin Brown, who mostly played slot cornerback last season but is set to move back to more of a true safety role next to Zachman.
"(Brown) hasn't been a big-time starter maybe in the last few years, but as talented of a football player as we have on the team," Fickell said. "I really look for him to be a guy that is going to take some of those next steps."
The other name that the head coach identified on his defense was junior linebacker Christian Alliegro.
He was a rotational player last season before he started the final three games, and he's set to lead the interior of a defense that needs to show some significant improvement this year.
"[Alliegro] is more in the mold of what the people of Wisconsin would grow to expect from some of those linebackers that are playing in the NFL," Fickell said.
Luke Fickell called #Badgers LB Christian Alliegro uniquely talented and someone that's quickly gaining confidence:

"He could be one of those next guys, ability-wise, to be what (media) have expected and seen here at the linebacker position."
He didn't compare Alliegro to any former Badgers directly, but that mold of previous Wisconsin linebackers includes the likes of Leo Chenal, Ryan Connelly and T.J. Edwards among others.
Fickell has high expectations for what some of the returning members of his defense can elevate to this season. When paired with their transfer portal additions, the Badgers are optimistic for finding more consistency on that side of the ball in 2025.
