Lions' D stiffens after opening drive

Posted by ESPN.com's Adam Rittenberg

ANN ARBOR, Mich. -- Michigan's speed looked like it would be a problem for Penn State's nationally ranked defense early on, as the Wolverines marched 70 yards on the game's opening drive.

But since then, the Lions have totally shut down Rich Rodriguez's offense. Since the opening march, Michigan has only 119 yards at the end of three quarters as Penn State leads 32-10.

Penn State linebacker Navorro Bowman and defensive end Jack Crawford both are having huge games, as they've made things hellish for Michigan quarterbacks Tate Forcier and Denard Robinson. Turnovers have been a major problem for the Wolverines, who look chaotic and undisciplined on offense. Forcier and Robinson are a combined 7 of 24 on passes today.

Michigan defensive end Brandon Graham has been fabulous today, but he's the only star for the Maize and Blue.
