Every Sunday, I'll release my latest Big Ten Power Rankings following all the previous day's action. Get my Week 2 rankings below:

1. Ohio State (1-0) - You knew the defense was going to be as strong as always, but there was still some doubt how Terrelle Pryor would play entering the season opener against Marshall. Would Pryor build off last year's impressive Rose Bowl performance, or would he regress and fall back into bad habits? The junior quarterback played great and looked comfortable under center, and that makes Ohio State the clear-cut top team.
Last Week: No. 1
Next Game: Miami, Sept. 11

2. Iowa (1-0) - No Brandon Wegher and no Jewel Hampton, no problem. The Hawkeyes are deep at running back, as they proved last season, and Adam Robinson's 152-yard, three-score day showed the team will have no shortage of backs this season. And just imagine what Iowa will be able to do in the running department when Hampton, Shonn Greene's backup in 2008, returns from suspension.
Last Week: No. 2
Next Game: Iowa State, Sept. 11

3. Wisconsin (1-0) - No team is more predictable than the Badgers, and yet the recipe always yields success. Wisconsin, the Big Ten's elite rushing attack over recent years, piled up 278 yards and four scores on the ground in its 41-21 victory at UNLV. Scary thing is, the Badgers aren't just a run-the-ball-down-your-throat team anymore with the emergence of fleet-footed James White.
Last Week: No. 3
Next Game: San Jose State, Sept. 11

4. Penn State (1-0) - Without getting too carried away by a debut against Youngstown State, of all teams, Rob Bolden sure looks legit. He's going to encounter his share of struggles against Alabama and the Big Ten, of course, but Bolden has the talent to turn Penn State's glaring weakness entering the season (QB) into a possible strength.
Last Week: No. 4
Next Game: @ Alabama, Sept. 11

5. Michigan State (1-0) - Everybody knew about the weapons in the Michigan State passing game entering Saturday's opener against Western Michigan. It was the team's running game that was the problem area. After one game, the Spartans appear to boast an improved rushing attack. True freshman Le'Veon Bell scampered for 141 yards and a pair of scores and Edwin Baker added 117 yards and two scores to give Michigan State its best ground day since Javon Ringer was in East Lansing.  
Last Week: No. 5
Next Game: @ Florida Atlantic, Sept. 11

6. Northwestern (1-0) - The Wildcats barely survived SEC doormat Vanderbilt, sure, but the game was on the road and the team was breaking in quarterback Dan Persa. Persa dazzled, completing 19 of 21 passes and amassing 304 total yards, although the offense continues to get nothing out of its running backs. Take away Persa's 82 rushing yards, and Northwestern mustered just 61 yards on the ground.
Last Week: No. 7
Next Game: Illinois State, Sept. 11

7. Michigan (1-0) - Connecticut is no slouch, so if Denard Robinson can play half as well as he did Saturday the rest of the way, the Wolverines will take it. Robinson torched the Huskies for 383 total yards, including a Michigan quarterback record 197 rushing yards, in the 30-10 win. Even more surprising, however, was the defense, which "held" UConn, an eight-win team a year ago, to 343 total yards.
Last Week: No. 8
Next Game: @ Notre Dame, Sept. 11

8. Purdue (0-1) - Purdue, perhaps, drew the toughest Week 1 draw of any Big Ten team. Add to that the fact Robert Marve was starting his first game since 2008, and you can understand how the Boilermakers lost at Notre Dame. At this time, the Boilermaker offense isn't what will be, and once it gets on track (no pun intended), Purdue should look a lot better on offense.
Last Week: No. 6
Next Game: Western Illinois, Sept. 11

9. Indiana (1-0) - Darius Willis in Indiana's wild card. The Hoosiers have never had a feared running back under Bill Lynch, but if Willis' unreal first-half performance against Towson -- mind you -- is a sign of things to come, Indiana's offense is going to give opponents fits.
Last Week: No. 9
Next Game: @ Western Kentucky, Sept. 18

10. Minnesota (1-0) - It was far from a thing of beauty, but Thursday's win at Middle Tennesse was a win. The revamped defense looked much better than expected, although the performance did come against a non-BCS team missing its stud quarterback. The bigger question continues to be QB Adam Weber, who hasn't seemed like the same talent since his sophomore season.
Last Week: No. 11
Next Game: South Dakota, Sept. 11

11. Illinois (0-1) - All is not lost, Illini fans. Not only does your team always seems to struggle against border rival Missouri, but there's a silver lining to this most recent season-opening defeat: The defense, the much maligned unit, limited the prolific Blaine Gabbert to 281 passing yards on 48 attempts (5.8 yards per attempt).    
Last Week: No. 10
Next Game: Southern Illinois, Sept. 11
