QB play gets passing grade

ANN ARBOR, Mich. -- One of the most electrifying players in college football touches the ball for Michigan on nearly every play. One of the Wolverines' biggest strengths is the man taking mostly shotgun snaps from center David Molk: Denard Robinson.

Yet the junior quarterback, for one reason or another, hasn't looked like the man who surprised college football in 2010. His passing numbers have dipped. While his rushing production is still high, the numbers are starting to drop as they did a season ago when Michigan entered Big Ten play.

So where does Robinson stand? What has he done well and where is he struggling? And what of reserve quarterback Devin Gardner, who seems to be slowly carving out a niche in the Michigan offense?
