All the Big Ten teams play their final game next week (except Illinois, which ends the season in two weeks against Fresno State), so as usual, things are going to get decided there pretty soon. The conference champion is presumably head to the Rose Bowl unless at least 4 teams above them lose, which seems very unlikely.
Right now, there's a 3-way tie atop the Big Ten, with Wisconsin, Ohio State, and Michigan State all 6-1 in conference, and 10-1 overall.
1. If both Ohio State and Michigan State win, the highest rated team in the BCS goes to the Rose Bowl, since it either would be a 3-way tie (if Wisconsin also wins), or a tie between OU and MSU (who did not play each other this year). This is currently Wisconsin, but it's close enough that it's up to the notoriously fickle human voters.
2. If only Michigan State loses, Wisconsin gets the Rose Bowl bid (as they beat Ohio State).
3. If only Ohio State loses, then Michigan State gets the bid (as they beat Wisconsin).
Better to make the mistakes when they don't count...perhaps then adjustments can be made before the real thing starts. Besides, at this rate it won't matter. If they can't SCORE, what's the difference between losing 3-0, 9-0 or 70-0?
