The vitriol was magnified from 1969-78, when curmudgeonly Woody Hayes was on the Buckeyes' sideline and Michigan was coached by the similarly stubborn and hardheaded Bo Schembechler.
Legend has it Hayes once ran out of gas in Michigan, but pushed his car over the state line rather than spend his money there.
That kind of passion has been handed down generation to generation and will be on display in "The Game," as the annual showdown has become known.
