what are unbeaten seasons ruined in the past michigan ohio state games?

Answer 1

Before this season, they'd met five times during the season when each of them had perfect records. In 1902, 1906 and 1933, they played early in the season when both were perfect. This will be the third time they've met in the last game of the regular season when both teams have perfect records - in 1970 the Buckeyes won 20-9, and the two teams tied 10-10 in 1973.
