This coming weekend we have essentially the Big Ten Semifinals. Ohio State will face Indiana, where the winner will all but wrap up the East in this truncated season. Northwestern will also face Wisconsin in a similar situation in the West. The Badgers and Buckeyes are both heavily favored to win their divisions, but Indiana and Northwestern have both shown they can be challengers.
Then there is the rest. Outside of those four there is a pretty significant gap to the rest of the league. Penn State is the one winless team, but Michigan, Illinois, Michigan State, Minnesota, Nebraska, and Maryland have had moments of looking absolutely awful.
