The last 4 wins for Iowa in Madison were:
2015, 2009, 2005 and 2003.
2015 Iowa team: 12-2 (Finished the season ranked #9)

2005: Iowa team 7-5. (Finished unranked. This was the Mitch King game.)
2003: Iowa teams 10-3 (Finished the season ranked #8).
Iowa teams have to be REALLY good to win at Madison.
This past summer, I thought with new coaches at Wisconsin and expectations of an improved offense, that Iowa had no less than a 40% of winning this game.
This past summer, you could bet this game, with Wisconsin as a 4.5 point favorite.
Now, there is a reason why the over/under is 36 and Wisconsin is favored by 10.
The market is saying a 23-13 Wisconsin win.
