The top challenger to Ohio State's College Football Playoff hopes could be its biggest rival.
Michigan enters "The Game" on a four-game winning streak that boosted it up to No. 13 in Tuesday's CFB Playoff rankings.
If Jim Harbaugh earns his first win in the rivalry, the playoff picture will be altered with one week left to play.
However, Ohio State has not displayed many flaws and it may take a perfect performance from the Wolverines to come out on top.
The postseason outlook could also change if Alabama stumbles against Auburn in the Iron Bowl.
