WIWH (Why is Wisconsin Here division):

Ohio State (5-0): They can lock up a place in the Big Ten title game by winning two of their final three or with 1 win and a Wisconsin loss.
Remaining games: @Illinois, vs. Indiana, @Michigan

Wisconsin (4-1): Can win a share of the divisional title with an Ohio State loss, but need to win out and have Ohio State lose 2 to go the Big Ten Championship Game for the 3rd year in a row.
Remaining conference games: vs. Indiana, @Minnesota, vs. Penn State

WIW (Where is Wisconsin division):

Michigan State (5-0): If MSU wins this week, all they need to clinch a spot in the CCG is winning either of their last two or Minnesota dropping one of their last 3. If they lose this week, they likely need to win out and have Nebraska lose one of its final two.
Remaining Games: @Nebraska, @Northwestern, vs. Minnesota

Nebraska (4-1): If Nebraska loses this week, they are out of the running to go to the Big Ten Championship Game. If they win however, they control their own destiny and will go by winning out. If they win this week, but drop one of the last two, they need Minnesota to lose one extra game.
Remaining Games: vs. Michigan State, @Penn State, vs. Iowa

Minnesota (4-2): Minnesota needs to win out, needs Nebraska to lose one of its final 3, and Michigan State to lose both to Minnesota and to another school. If at least that happens, Minnesota will win all tie breakers with both Michigan State and Nebraska.
Remaining Games: vs. Wisconsin, @Michigan State
