After a few full weeks of conference play, action in the Big Ten is heating up, with a lot of changes in this week’s power rankings coming from the bottom half of the conference. Here’s the Big Ten power rankings after Week Seven:

1. Ohio State (6-0, 3-0 B1G)

Last Ranking: 1

Last Result: 49-20 win at Michigan State

Next: vs. Iowa

Ohio State had a bye week last week, giving it extra time to prepare for this week’s matchup against a stingy Iowa defense.
