1969 Ohio State vs. Michigan football game

The 1969 Ohio State vs. Michigan football game is considered to be one of the best-known games of the series, as well as one of the biggest upsets in college football history. The Buckeyes went into the game as the top-ranked team in the country, with a 22-game winning streak under the direction of head coach Woody Hayes. They were also defending national champions. The Wolverines went into the game under a new head coach, Bo Schembechler, who was trying to redefine a college football power that had fallen on hard times. Ohio State was playing for its second straight national title, while Michigan was playing for the Rose Bowl, and the championship of the Big Ten Conference was on the line. The game was witnessed by a (then) stadium-record crowd of 103,588 at Michigan Stadium in Ann Arbor, and began the highly combative stretch of the rivalry informally known as The Ten Year War.
