ANN ARBOR, Mich. (AP) - Michigan coach Brady Hoke acknowledges he doesn't know what his team's identity is through seven games. Hoke wants the Wolverines to have a powerful offense that runs the ball early, often and effectively with its running backs. On defense, he wants his linemen to get off blocks, linebackers to make tough tackles and defensive backs to pick off or deflect passes. So far, those things haven't happened consistently. The 24th-ranked Wolverines got through the easier stretch of their schedule with six wins and only one loss. Each of the last five games, though, potentially present problems for Michigan. After a bye, the Wolverines will close the regular season at Michigan State, against Nebraska, at Northwestern and Iowa before hosting rival Ohio State in the last regular season game.
