Big Ten power rankings

1. Iowa (11-0, 7-0): Eleven wins are the most in Hawkeyes history, matching the 11-2 seasons in 2002 and 2009.

2. Michigan State (10-1, 6-1): A win over Penn State would send the Spartans to third their Big Ten title game in six years.

3. Ohio State (10-1, 6-1): The defense is playing at a championship level. But the offense is surprisingly stagnant.

4. Michigan (9-2, 6-1): Jake Rudock is the first Michigan quarterback with three straight games of at least 250 yards passing.

5. Northwestern (9-2, 5-2): Pat Fitzgerald, after the Wisconsin win: "I don't know who just won. What just happened?"

6. Wisconsin (8-3, 5-2): The Badgers average 138.2 rushing yards per game, down from a Big Ten best 320.1 last year.

7. Penn State (7-4, 4-3): The Nittany Lions gave up 10 tackles for loss, including four sacks, against Michigan.

9. Gophers (5-6, 2-5): KJ Maye averages 6.1 catches per game in Big Ten play, tied for second most in conference.

10. Illinois (5-6, 2-5): The Illini can still reach a bowl game with a win over Northwestern on Saturday at Soldier Field.

11. Indiana (5-6, 1-6): Hoosiers need to win the Old Oaken Bucket at Purdue for their first bowl bid since 2007.

12. Purdue (2-9, 1-6): The Boilermakers likely won't have QB David Blough (concussion) for the Indiana game.

13. Rutgers (4-7, 1-6): Hard to focus on work with all the anticipation for Saturday's Rutgers/Maryland tussle.
