The Big Ten is a dangerous place to play, and it showed last week.
Monday, teams that were hit with upsets paid for it, as Michigan State fell a couple spots, Iowa dropped in the rankings and Wisconsin and Ohio State dropped out of the AP top 25 altogether, leaving just three ranked Big Ten teams.
Wisconsin's fall was the largest, dropping from No. 14 completely out after home losses to Northwestern and Ohio State. The Buckeyes, despite that win over the Badgers, were punished for their midweek loss to Penn State, one that came in Columbus. They were ranked No. 24 last week before dropping out on Monday.
Despite the Badgers and Buckeyes falling out of the rankings, however, they were the first and second teams listed in the others receiving votes category, meaning good weeks could get them right back in the top 25.
Iowa had an up-and-down week of its own, losing at home to Michigan State before going on the road to beat Illinois, but even that win over the Illini required a second-half comeback after blowing a 21-point lead in the first half. They dropped from No. 15 to No. 17.
Michigan State fell two spots from No. 7 to No. 9 after a loss to Georgetown, while Michigan remained at No. 10 despite losing at Indiana on Sunday.
The biggest game of the upcoming week that will have the biggest impact on the rankings is Saturday's matchup between the Wolverines and Hawkeyes in Iowa City. But as was found out this past week, each game is a dangerous one in this year's Big Ten.
