Who Wins The Big 10 (Situational)?

They would share the big ten title. It would just depend on what the rest of the college football world did as far as the BCS. If they are 1-2 in the polls, then they would play. As a side note, if OSU loses to USC, and then runs the table, and Iowa goes undefeated, then they would still split the big ten title, since the loss came out of conference.
