1. Michigan vs. Ohio State
When Ohio Stadium opened in 1922, Michigan spoiled the party with a 22-0 victory. The rivalry was heated in the early days as both have been long-time college football powers. But it got even hotter in 1969, when Bo Schembechler took over as Michigan's coach and upset Woody Hayes' No. 1-ranked, undefeated Buckeyes. Four times in the next six years, both teams were ranked in the top five when they met. In 1970 and 1973, both were undefeated (they tied 10-10 in '73). From 1970 through 1975, Michigan entered without a loss every year. The Wolverines won just once. Ohio State was 9-0-1 in 1993, 11-0 in 1995 and 10-0 in 1996. The Buckeyes lost each time. That is rivalry.
