Every Tuesday during the season I will release league power rankings, which you can find under the College tab at the top of this page. The six BCS conferences will all have their own power rankings, while I will also rank the best of the non-BCS squads.

With that in mind, let's take a look at how the Big Ten shapes up:

1. Ohio State (5-0): The Buckeyes were able to keep the Michigan State ground game in check in a 17-16 win over the Spartans.

4. Michigan State (3-2): The Spartans lost their fourth home game in a row to Ohio State, 17-16.

5. Michigan (2-2): The Wolverines were off this past weekend and will travel to Purdue on Saturday.

6. Wisconsin (3-2): Montee Ball scored three short touchdowns but was otherwise bottled up by the Nebraska defense in a road loss.

7. Penn State (3-2): Zach Zwinak rushed for 101 yards and two touchdowns, and the Nittany Lions forced three turnovers in a 35-7 win over Illinois.

8. Purdue (3-1): Caleb TerBush threw for four touchdowns and the Boilermakers returned two interceptions for scores as they held on for a 51-41 victory over Marshall.
