Wisconsin wasn't as good as advertised when it steamrolled its first six opponents by an average of 38 points. But the Badgers aren't as bad as they looked in a 38-7 loss to Ohio State two weeks ago and in letting themselves get upset by Illinois before that game in an obvious look-ahead spot to Ohio State.
The Badgers had a much needed bye last week. I see a regrouped Badgers squad taking care of Iowa at home. Wisconsin is 16-5 ATS following a bye. Both teams are tough defensively. The difference is Wisconsin has a stud RB in Jonathan Taylor, who I consider the best RB in the country. 
Iowa ranks 94th in scoring offense averaging only 24.4 points a game. The Hawkeyes could be minus star offensive lineman Alaric Jackson, too. 
Wisconsin has won the last three in the series.
