Only eight games on the slate this week, but there's no shortage of subplots, especially on the defensive side.
Let's take a look:
1. Ringer vs. the world: Notre Dame will do all it can to stop Michigan State's Javon Ringer on Saturday (ABC, 3:30 p.m. ET). Ringer likely can expect to see eight or nine men in the box, as the Fighting Irish dare Brian Hoyer to beat them. The overloading still might not be enough, as Ringer has racked up 417 rushing yards and seven touchdowns in his last two games.
2. Pryor's coronation in Columbus: Terrelle Pryor and Todd Boeckman will split snaps for Ohio State against Troy, but this game is a chance for the freshman to take control of the offense. If Pryor continues to show good poise and playmaking ability, he'll continue to be featured when the Buckeyes enter Big Ten play. Boeckman will get his opportunities as well, but with the top goal off the table for the Buckeyes, they have to look toward the future.
3. Iowa D takes on real McCoy: The Hawkeyes have already collected eight takeaways without allowing a touchdown this season, but they face their first major test in Pitt running back LeSean McCoy. Expect McCoy to run away from Iowa star tackles Mitch King and Matt Kroul, which will put pressure on less proven players to step up.
4. Indiana on the defensive: I've already heard from several furious Hoosiers fans about my upset pick of Ball State against their unproven team. Let's see if an improved Hoosiers defense proves me a fool when it faces dynamic quarterback Nate Davis and FBS receiving leader Dante Love. There's no doubt Kellen Lewis will make plays for Indiana, but the team's fate, as usual, rests with the defense.
5. Northwestern chases history: Nonconference losses have been Northwestern's biggest bugaboo, even during the program's renaissance in the mid-1990s. The Wildcats can sweep their nonleague slate for the first time since 1963 by beating Ohio at home. It won't be easy, as the Bobcats are much better than their record indicates and athletic quarterback Boo Jackson spells trouble for an improved Northwestern defense.
6. Tiller gets record: Joe Tiller already should be Purdue's all-time winningest coach, but his team lost another winnable big game last Saturday against Oregon. Tiller sets the record this week as Curtis Painter and the Boilermakers pick apart a Central Michigan defense that looks overmatched against BCS foes. Dan LeFevour makes the game interesting for a while, but Purdue beats the Chippewas for the third straight time.
7. Gophers secondary tested: No one would mistake Minnesota's nonleague schedule for, say, Washington's, but the Gophers deserve a ton of credit if they go 4-0 after winning one game all of last season. Standing in their path is Florida Atlantic quarterback Rusty Smith, who will perform much better than he did in the rain last week in East Lansing. Minnesota's new-look secondary of Tramaine Brock, Traye Simmons, Marcus Sherels and Kyle Theret have shown good playmaking skills so far and need continued progress against the Owls.
8. Iowa quarterback Jake Christensen: Coach Kirk Ferentz seems to be telling Christensen, "Take the job already, will ya?" The junior gets a great chance to do so on the road against a desperate Pitt team already knocked off its preseason perch. Christensen steadied the offense in the clutch last week against Iowa State but will need to make more pressure plays against the Panthers.
9. Penn State's defensive line: Coach Joe Paterno admits his team hasn't faced any adversity so far this season, at least on the field. Temple quarterback Adam DiMichele should be a good challenge for Penn State's defensive linemen, who have held together nicely despite injuries, dismissals and suspensions. Paterno also should address the status of linemen Maurice Evans and Abe Koroma after the game.
10. Michigan State safety Otis Wiley: Wiley once again looks like the guy who led the team in tackles (94) and pass breakups (10) as a sophomore in 2006. The Spartans need him at his peak against Notre Dame because of lingering personnel issues in the secondary. Fighting Irish quarterback Jimmy Clausen will look to stretch the field with Golden Tate, and it's up to Wiley to limit the damage.
