Big Ten football power poll

1. Ohio State (6-0, 2-0): Wisconsin and Northwestern played the Buckeyes tougher than Michigan figures to Nov. 30.

2. Michigan (5-0, 1-0): Went 25 games in a row with at least one turnover before last week's victory over the Gophers.

3. Northwestern (4-1, 0-1): Trevor Siemian leads Big Ten in pass efficiency (171.3); teammate Kain Colter is third (160.2).

4. Wisconsin (3-2, 1-1): Will there be a letdown now that Ohio State has all but wrapped up the Leaders Division?

5. Michigan State (4-1, 1-0): Leads the nation in total defense, allowing just 203.8 yards per game.

6. Nebraska (4-1, 1-0): Taylor Martinez (turf toe) likely sits through the bye week, returning Oct. 26 at Minnesota.

7. Iowa (4-2, 1-1): Bye week, then hold on tight, as Hawkeyes play Ohio State, Northwestern and Wisconsin.

9. Penn State (3-2, 0-1): The Nittany Lions rushed for just 70 yards in their 44-24 loss to Indiana.

10. Illinois (3-2, 0-1): Second bye in four weeks gives the Illini more time to work on their defensive woes.

11. Gophers (4-2, 0-2): Ra'Shede Hageman ranks fifth in the Big Ten with 6½ tackles for a loss.
