• What they do well: The Spartans have one of the league's best running backs in Javon Ringer, and a defense that is tied for fourth nationally in sacks.

• What IU can exploit: The Spartans gave up 525 yards passing last week against Northwestern. Good news for Kellen Lewis, James Hardy and Co.

• Big dog or underdog? Big dog. IU won 46-21 at home last year, and a win makes IU 6-1 for the first time since 1993.

Second chance

Oct. 20 vs. Penn State (4-2, 1-2)
• What they do well: Nittany Lions rank eighth nationally in stopping the run, and Anthony Morelli leads a potent offense (31.8 ppg).

• What IU can exploit: The Hoosiers are third in the Big Ten in turnover margin, and Penn State has turned it over 16 times this season.

• Big dog or underdog? Underdog given Penn State's reputation, but IU could benefit from their largest crowd of the season for homecoming.
Third chance

Can IU's resurgence continue?
