Nasty weather precludes an effective deep-threat passing game.
Michigan's offense exceeds expectations against an overrated Nittany Lion defense that hasn't faced a credible offense all season. Michigan's short-to-medium passing game and run offense (led by the return of David Molk) are too much for the Nittany Lions who are cold, wet, and increasingly frustrated by the offense's inability to move the ball downfield.
Michigan's defense gives up one big play and the Michigan offense turns the ball over, setting up a second Penn State score. After that, it's smooth sailing for the Wolverines after a series of halftime adjustments.
Michigan 31—Penn State 17.
