Penn State Nittany Lions: power rankings 102813

Northwestern has made its exit from the Big Ten's top half and shows no signs of returning. Now it's Nebraska's turn to be shown the door. Meanwhile, we welcome an unexpected visitor in Minnesota to the top half of the power rankings.

Minnesota's historic upset of Nebraska provided the major shake-up in this week's rundown. The Gophers, who were No. 11 two weeks ago, have turned around their season with upset wins against both Northwestern and Nebraska. They've guaranteed a second consecutive bowl appearance and can make some noise in the Legends Division down the stretch. Iowa also looks like it will be going back to the postseason after an overtime win against Northwestern.

Michigan State moves up to No. 3 after pulling away from Illinois in Champaign, while Iowa moves up after its overtime win against slumping Northwestern. Penn State's historically bad night at Ohio State bumps the Lions down a few pegs.

Let's take one last look at the Week 8 rankings.

Now, for the fresh rundown:

1. Ohio State (8-0, 4-0 Big Ten; last week: 1): There was no need for a second-half surge as Ohio State throttled Penn State from the get-go, picking up an easy win and the style points it has looked for in Big Ten play. After his near benching at Northwestern, quarterback Braxton Miller has performed like a Heisman Trophy candidate, picking apart Penn State's defense for 252 passing yards and three touchdowns. Ohio State racked up its highest-ever yardage total (686) against a Big Ten foe. The Buckeyes' defense recorded three takeaways. Ohio State now visits Purdue, a recent trouble spot.

2. Wisconsin (5-2, 3-1; last week: 2): The nation continues to sleep on the Badgers, but at some point the credit will come if Gary Andersen's crew continues to win. Wisconsin's second open week came at a good time as star linebacker Chris Borland had some extra time to heal from a hamstring injury. Borland should be good to go for this week's trip to Iowa, as Wisconsin reunites with its longtime rival for the first time since 2010. Andersen likes the way quarterback Joel Stave is progressing, and this week's game should provide a nice gauge.

3. Michigan State (7-1, 4-0; last week: 4): After a one-year hiatus, Michigan State is back in the Big Ten title race. The Spartans are the only Legends Division team without a Big Ten defeat and can take a huge step toward Indianapolis by beating rival Michigan this week. Quarterback Connor Cook and the offense got on track against Illinois, racking up 42 points and 477 total yards. When Cook is in rhythm, Jeremy Langford finds running room and the offensive line controls play, Michigan State is tough to beat. But the challenges will get tougher now.

4. Michigan (6-1, 2-1; last week: 5): Who are these Wolverines? The young, talented group that beat Notre Dame in September or the shaky, flawed squad that hasn't looked very impressive since Sept. 7? We'll finally get some real answers as Michigan begins a challenging November stretch this week at Michigan State. Devin Gardner and the offense scored at will against Indiana but face an exponentially tougher challenge against the Spartans' nationally elite defense. A second Big Ten loss would make it tough for Michigan to reach Indianapolis, given the remaining schedule.

5. Iowa (5-3, 2-2; last week: 7): After struggling against Northwestern's Kain Colter last year, Iowa's defense stepped up in a big way, shutting out the Wildcats for a half and recording six sacks, its highest total since the 2008 season. The linebacking corps was terrific, and so was Drew Ott. Quarterback Jake Rudock wasn't great but made the big throw when it counted to C.J. Fiedorowicz in overtime. Iowa is a win away from becoming bowl eligible as rival Wisconsin comes to Kinnick Stadium this week. The Hawkeyes get the edge against Minnesota for the five spot after dominating the Gophers at TCF Bank Stadium.

6. Minnesota (6-2, 2-2; last week: 8): Two weeks ago, many were wondering if Minnesota would make a bowl game and if head coach Jerry Kill would step down because of his health issues. While Kill's future remains somewhat in doubt, he has been in the coaches' booth to watch his team record upset wins against Northwestern and Nebraska. Saturday's dominant performance against the Huskers marked Minnesota's first win against Big Red since 1960. The Gophers received big performances from running back David Cobb (138 yards), defensive linemen Ra'Shede Hageman and Theiren Cockran and others. Minnesota could be a surprise contender in the Legends Division if it continues to win this week at Indiana.

7. Nebraska (5-2, 2-1; last week: 3): A four-spot drop in the rankings for one loss might seem harsh, but Nebraska invalidated any perceived progress since the UCLA game by struggling in all three phases in a loss at Minnesota. Despite his big-game flaws, Bo Pelini's teams typically had won the games they should win, but the Huskers fell apart after building a 10-0 lead. Quarterback Taylor Martinez looked very rusty and the defense couldn't stop Minnesota's ground game. Nebraska tries to get well against slumping Northwestern this week in Lincoln.

8. Penn State (4-3, 1-2; last week: 6): There will be better nights for quarterback Christian Hackenberg and Penn State, which fell behind quickly at Ohio State and never challenged the Buckeyes in the ugliest loss of the Bill O'Brien era. Penn State's defensive issues are very real, though, as the Lions have allowed more than 40 points in three consecutive games for the first time since 1899 (!). Hackenberg's health will be a storyline this week as Penn State faces Illinois. At least the Lions don't have any more open weeks.

9. Indiana (3-4, 1-2; last week: 9): It's still all about fixing the defense for Indiana, which had no answers for Jeremy Gallon, Gardner and Michigan in Week 8. The IU offense can strike and strike quickly, regardless of whether Tre Roberson or Nate Sudfeld is playing quarterback. Kevin Wilson's crew enters a critical home stretch against Minnesota and Illinois. IU likely needs to win both to have a chance of going bowling this year.

10. Northwestern (4-4, 0-4; last week: 10): Halloween arrives Thursday, but the nightmare has lasted four weeks for the Wildcats, whose October woes have reached a new low under Pat Fitzgerald. All of Northwestern's hallmarks -- great ball security, limited penalties, being great in the clutch -- seem to be going out the window. Fitzgerald has blamed himself and his staff for the recent struggles, and it's hard to disagree after the ultra-conservative decisions late in Saturday's loss to Iowa. Northwestern heads to Nebraska this week, as misery loves company.

11. Illinois (3-4, 0-3; last week: 11): The Illini's fast start seems like a distant memory now as they've been swallowed up in Big Ten play. Illinois' second consecutive home blowout loss makes a bowl game highly unlikely, and there are issues to address on both sides of the ball. A young defense is getting exposed by power running teams, as Michigan State had its way with the Illini. Bill Cubit is a creative play-caller, but Illinois needs something more against Big Ten defenses. Illinois had a meager eight first downs and 128 total yards against Michigan State.

12. Purdue (1-6, 0-3; last week: 12): The Boilers entered their second bye week feeling a bit better than they did entering their first. A stout defensive performance against Michigan State, particularly by Bruce Gaston and his fellow linemen, provides Purdue something to build on before the stretch run. Purdue now needs to get something going on offense. Ohio State comes to town this week, which should be special for Purdue coaches Darrell Hazell and Marcus Freeman.
