A sheep in wolf's clothing? Penn State looks to prove it's legit

This will be the first test for either team. Per Pro Football Focus, Penn State's strength of schedule ranks 85th out of 131 teams. Michigan's rank at 97th is even less impressive.

Considering Penn State's collapse and Michigan's ascension a year ago, it's fair to have less faith in Penn State.

Penn State peaked fourth in the Associated Press poll before finishing unranked. Michigan began unranked and finished third.

Penn State has improved on offense. Last year, the team averaged 3.2 yards per rush. This year, they're averaging 4.9 yards. The team is averaging 34.4 points, up from 25 points.

Through five games last year, Penn State averaged 30 points. The team's drop in production coincided with the more difficult competition.

Going forward, Penn State's strength of schedule is 18th.

They will have their first opportunity to regain the trust of the college football world against Michigan (6-0, 3-0). 

Michigan's run defense is stout, allowing 2.6 yards per attempt. The Wolverines are led by star running back Blake Corum. He has 735 rushing yards through six games and has emerged as an early contender for the Heisman Trophy. 

In last year's 21-17 loss, Penn State allowed 156 yards on 31 carries to running back Hassan Haskins.

With games against Michigan and No. 2 Ohio State the next month, it won't be long until the real Penn State (5-0, 2-0) reveals itself. The Nittany Lions will not only be battling two of college football's juggernauts. They'll also be confronting their own ghosts.
