When I project out the remaining schedules in the Big XII north I come up with ISU, Neb, and Mizzou all at 4-4 atop the division. If these three teams finish in a 3 way tie who advances on to the championship game??? Keep in mind that in this scenario ISU beat Neb, Neb beat Mizzou, and Mizzou beat ISU.
(Of course if ISU can take care of the games I think they 'should' win: A&M, CU, and Mizzou this would be a mute discussion and ISU would advance at 5-3)
