Rick Kaczenski, former Nebraska defensive line coach, slammed Indiana head coach Tom Allen ahead of Saturday's Big Ten matchup.

On Hail Varsity Radio, Kaczenski stated that the Cornhuskers' victory over the Hoosiers is "absolutely critical."

"Let’s be honest, Tom Allen, is there a bigger clown in college football than that guy?" Kaczenski said. "For the love of god, we cannot lose to Indiana. We can't."

"I don't like coaches who like to run out of tunnels," he explained. "I enjoy the crowd. Isn't that what I'm into? However, guess what? Nobody is around to witness my dash out of the tunnel."

Kaczenski may not be the best character judge. He was arrested and charged with third-degree domestic assault in 2015.

His wife claimed he slashed her forehead open with a picture frame. Kaczenski admitted to police that she was involved in the incident.

Allen has led Indiana to a 3-1 start after going 2-10 last season. Meanwhile, Nebraska dropped to 1-3 after being thrashed by Oklahoma two weeks ago.
