I'm not sure what came of that report that Drake Harris was joining the basketball team, but he's definitely more useful as a receiver than defensive-back.
The defense should be good enough for Michigan to win, no matter how the offense looks. Indiana has had a lot of turnovers, so I fully expect Michigan to get at least one defensive score or at least put the offense in great field position to do so. Their defense hasn't been that great, either. Also, John O'Korn was the starter when Michigan won this game last year, as ugly as it was. If the offense gets the TEs more involved they should be able to get some decent big plays like they did against Purdue. Keeping the defense honest by trying to throw it deep a few times will also help the running game, which looked better against Sparty. Of course, special teams could make a big difference, as well.
