See my full latest poll below.

1. Penn State (5-0, 2-0). Another week, another impressive win. Tell Saquon to start picking out a suit to wear to the Heisman ceremony.
Last week: 1
Up next: at Northwestern

2. Wisconsin (4-0, 1-0). Is there a more underrated defense in America? Nope. Big hurdle this week under the lights in Lincoln.
Last week: 2
Up next: at Nebraska

3. Michigan (4-0, 1-0). The Wolverines were off, giving them extra prep time for Michigan State–and for Jim Harbaugh to perfect the Triple Lindy.
Last week: 3
Up next: Michigan State

4. Ohio State (4-1, 2-0). What did we learn the last three weeks about the Buckeyes vs. Army, UNLV and Rutgers? Not much.
Last week: 4
Up next: Maryland

5. Maryland (3-1, 1-0). Come on, say it with: "Max Bortenschlager." It's fun. And it sounds like a menu item at a Bavarian pub. But he?s the BMOC in College Park.
Last week: 8
Up next: at Ohio State

6. Michigan State (3-1, 1-0). How long can QB Brian Lewerke continue to be a one-man gang for the Spartans? Gotta like how this defense is playing.
Last week: 9
Up next: at Michigan

7. Iowa (3-2, 0-2). That?s two losses in a row for the Hawkeyes. Stop me if you?ve heard this before: The offense needs more pop.
Last week: 5
Up next: Illinois

8. Purdue (2-2, 0-1). The Boilermakers were off last week, looking to tune-up an offense that did nothing vs. Michigan. If Purdue has any bowl dreams, it must beat the Gophers this week. Yes, I just typed that.
Last week: 6
Up next: Minnesota

9. Nebraska (3-2, 2-0). The Huskers have won two in a row. They were against Rutgers and Illinois, but who cares? NU just needs to win. Beat Wisconsin on Saturday, and anything may be possible.
Last week: 12
Up next: Wisconsin

10. Minnesota (3-1, 0-1). The 3-0 start is history, as the Gopher defense got ripped to shreds by an offense led by a third-team QB. And where is the Minnesota ground game? I have no idea how good this team is.
Last week: 7
Up next: at Purdue

11. Northwestern (2-2, 0-1). The offense lacks big-play ability. And how good is the o-line? The Wildcats are a bit of a mystery.
Last week: 11
Up next: Penn State

12. Indiana (2-2, 0-2). The banged-up Hoosiers need to find some answers on offense. And is there a QB controversy brewing?
Last week: 10
Up next: Charleston Southern

13. Illinois (2-2, 0-1). The growing pains continue for an Illini squad that is committed to a youth movement. Get used to it. More painful days loom.
Last week: 13
Up next: at Iowa

14. Rutgers (1-4, 0-2). The good news for the Scarlet Knights-they can?t lose this week. Why? Because they are off. Patience, please.
Last week: 14
Up next: off; at Illinois, Oct. 14
