The biggest weapons in the arsenals of No. 20 Michigan and No. 4 Ohio State are undoubtedly their quarterbacks.
Devin Gardner and Denard Robinson, who may line up everywhere but center due to an arm injury, are the speedsters who lead the Wolverines' attack. The Buckeyes rely on lightning-fast, dual-threat Braxton Miller.
Stopping, or at least slowing down, the trio will be the main objectives.
Gardner has come on recently to provide a passing game that the Wolverines had lacked with Robinson, the mercurial runner who will still play despite nerve damage to his right (throwing) elbow.
Miller is coming off one of his worst games in an unbeaten season. But Michigan remains on high alert.
