There’s no doubt Scott Frost was unhappy with how Nebraska performed in Saturday’s 41-23 loss to Illinois. Coming off the first win of the season in Week 4 against Penn State, the showing from the Huskers this weekend was disappointing.

Frost was quite blunt in his assessment of the game and knows that his team can’t dwell on it. With a red-hot Iowa team on the schedule this week, Nebraska needs to get the Illinois game out of its head and start focusing on the Hawkeyes.

“We’ve got to flush it fast,” Frost said, per Sam McKewon of the Omaha World-Herald. “That’s an effort and performance I don’t want to see repeated.”

Nebraska dropped to 1-3 after the loss and plays an Iowa team that has won three-straight games, defeating Michigan State, Minnesota and Penn State in consecutive weekends. The Huskers have lost five straight games to the Hawkeyes, and Frost is 0-2 against the rival.

Friday’s game is especially big for the Huskers, who must win out to have a chance to end the year on the right side of the .500 mark. Nebraska has not had a winning record under Frost.
