The contest was the first in the famous "Ten-Year War" between Hayes and Schembechler, which pitted some of OSU's and UM's strongest teams against one another. Four times between 1970 and 1975, Ohio State and Michigan were both ranked in the top five of the AP Poll before their matchup. The Wolverines entered every game during those years undefeated and won only once, a 10–7 victory in Ann Arbor on November 20, 1971. The Michigan graduating class of 1975 shared or won the Big Ten championship every season, yet went to the Rose Bowl only once, in 1972. They only lost or tied with Ohio State during the regular season in that period.
