Iowa coach Kirk Ferentz says the Hawkeyes made strides in wins over Northwestern and Purdue and will need to be even better this week at home against Wisconsin.
The Badgers have won five of the last six in the series and during that stretch have feasted on Hawkeye mistakes.
The Badgers are 3-1 since firing Paul Chryst and elevating defensive coordinator Jim Leonhard to interim coach. The Badgers are coming off a 23-10 win over Maryland.
Ferentz says the Badger defense does a good job of disguising pressure.
A consistent theme in this series has been the team that runs the ball the best has won the game.
