Defensive line

Both Northwestern and Penn State are strong up front on defense. The Wildcats have the Big Ten's best rushing defesne (90 rushing ypg), while Penn State has allowed just two rushing touchdowns this season. Penn State defensive end Pete Massaro is returning from a shoulder injury today to make Penn State's defensive line the healthiest its been in a while. In purple and white, Tyler Scott poses a threat off the edge, he has three sacks and four and a half tackles for loss this season.

Advantage: Push

Linebackers

Four of the Big Ten's top 12 tacklers are on either Penn State or Northwestern's roster. Michael Mauti leads the Nittany Lions with 48 tackles and two interceptions and is coming off a memorable afternoon last week against Illinois. Glenn Carson and Gerald Hodges have combined for 72 tackles. The Wildcats' Chi Chi Ariguzo has 39 tackles and an interception this season, and Damien Proby has 37 tackles this season. Though Northwestern has some talented players in its linebacking unit, Carson and Mike Hull give Penn State some more depth.

Advantage: Penn State

Secondary

As mentioned, neither team's secondary has really done anything to stand out this season. Northwestern has allowed 291 passing yards per game and has two interceptions in five games. Penn State's numbers against the pass a a little better, the team has given up and average of 227.8 yards through the air per game and as made four picks this season — though none by its secondary. Penn State safety Stephen Obeng-Agyapong did have some issues with cramps last week, but he should be ready to go against the Cats.

Advantage: Penn State
