After early season losses to #9 Missouri and unranked Michigan State, the Wolverines won four straight games before their showdown with heavily-favored and top-ranked Ohio State for the Big Ten championship. Michigan shocked the college football world by upsetting the top-ranked Buckeyes 24–12 to tie for the conference title and receive the Rose Bowl bid.[5][6][7] (Ohio State was ineligible anyway because of the Big Ten's "no repeat" rule,[8] which was rescinded in 1971.)
Just days before the Rose Bowl, first-year head coach Bo Schembechler, age forty, suffered a mild heart attack and had to miss the game;[9][10] defensive coordinator Jim Young was the acting head coach.[3]
Aided by a pass interference penalty on fourth down followed by a controversial last-minute touchdown, USC earned the Rose Bowl berth with a 14–12 win over rivalUCLA in their regular season finale.[11] The only blemish on their record was a 14–14 tie at Notre Dame in mid-October.[12] The Trojans were making their record fourth consecutive Rose Bowl appearance, as the Pac-8 did not have a "no repeat" rule.
