A week of games against mostly inferior competition doesn't provide the most accurate gauge of which teams go where, but it's a starting point. There are a few small moves in this week's rankings, which reward squads for how they looked and, in some cases, for who they played.
The middle five teams -- Penn State, Northwestern, Iowa, Michigan and Illinois -- still could be placed in pretty much any order, and it will take a bit of time to see separation there. But we do reward for quality wins, and Northwestern recorded one at Boston College under tough circumstances.
Let's get started.
1. Wisconsin (1-0): Quarterback transfer Russell Wilson and the Badgers made a strong opening statement on national TV. Wilson led the offense to scores on eight consecutive possessions before departing, and running back Montee Ball looked like a totally different player. The defense needs to tighten up when the competition gets better.
2. Nebraska (1-0): We're leaving Nebraska here for now, but we want to see a more polished performance from the offense this week against Fresno State. Not surprisingly, the offense had mixed results in its first game with the new system. The defensive line looked stellar as Cameron Meredith had a big opener.
3. Ohio State (1-0): The Buckeyes move up a spot after thoroughly dominating Akron on Saturday. Joe Bauserman stated his case to be the starting quarterback and tight end Jake Stoneburner hauled in three touchdown passes. The 42-0 score amazingly made the game seem closer than it actually was.
4. Michigan State (1-0): After a sloppy first half, Michigan State found a rhythm in the second half and pulled away from Youngstown State. Receiver B.J. Cunningham had a big night, but coach Mark Dantonio will look for greater efficiency and better discipline (eight penalties) from his squad this week against Florida Atlantic.
5. Penn State (1-0): The Lions didn't get much clarity at the quarterback position, but they didn't need it against Indiana State. Silas Redd led a potent rushing attack, and Penn State had a strong defensive effort and received a special teams boost from Chaz Powell on the opening kickoff return. Joe Paterno's squad has a great chance to make a national statement this week against Alabama.
6. Iowa (1-0): Kirk Ferentz saw some sloppiness in the opener, but Iowa had little trouble pulling away from Tennessee Tech. The Hawkeyes need running back Marcus Coker to rebound against Iowa State after two fumbles. Shaun Prater and James Morris had long interception returns to set up scores.
7. Northwestern (1-0): The Wildcats move up after recording the Big Ten's most impressive victory of Week 1. They beat Boston College on the road without star quarterback Dan Persa. The offensive line stepped up to spark backup quarterback Kain Colter and the run game, and the defensive front stuffed Boston College's run game.
8. Michigan (1-0): We don't know how the final 17 minutes would have played out Saturday, but Michigan was rolling against Western Michigan before the lightning came (again). The defense covered up issues with three takeaways, including two touchdown returns by linebacker Brandon Herron. The offensive line looked strong as it adapts to a scheme based more around power.
9. Illinois (1-0): This isn't a knock on Illinois, which pulled away from Arkansas State after a slow start. If the Illini keep winning, they'll climb the power rankings. The passing attack looked strong with quarterback Nathan Scheelhaase and receivers A.J. Jenkins and Darius Millines. Illinois' defense will need to tighten up before Arizona State arrives in Week 3.
10. Minnesota (0-1): Jerry Kill's squad didn't beat USC but gained a lot of respect for the way it fought against the 25th-ranked Trojans. Minnesota's defense struggled against the pass (304 yards) but limited points, and Gophers freshman quarterback Max Shortell showed impressive poise in relief of MarQueis Gray. Watch for Minnesota to make some noise this fall.
11. Purdue (1-0): It took a furious rally for the Boilers to beat Middle Tennessee, and Danny Hope's squad has plenty to work on in the coming weeks. The good news is the schedule favors Purdue, which faces Rice and Southeast Missouri State before an open week. Defense has to be the focus this week after Purdue surrendered 460 yards Saturday.
12. Indiana (0-1): Getting pushed around by Ball State at the line of scrimmage gets you a swift kick to the bottom of the power rankings. Indiana must get tougher up front on both sides of the ball, especially with Virginia visiting Bloomington this week. Quarterback Ed Wright-Baker did some good things, but IU must put together a more complete performance for new coach Kevin Wilson.
