Historical Big Ten Standings

I found a link that has Big Ten Standings going way back (links to different decades are in the left side column)

FYI:  going back to '93, Michigan and Ohio State have been ranked top 2 on 5 occasions, but in each of those ('97, 98', '03, '06, '07) there were ties for 2nd place (or 3way ties for 1st) so it's not clear what would have happened if there were divisions.  It depends on how the divisions are split.

They were both ranked top 3, 10 times, but two of those included ties for the 3rd place position.
