The national championship was on the line for #1 USC, and likely #3 Ohio State. Although #2
Oklahoma already had defeated
Penn State in the
Sugar Bowl on New Year's Eve to finish their season a win in the Rose Bowl for the Buckeyes might well have swayed the voters to put Ohio State at #1.
USC The USC Trojans won all eleven games in the 1972 regular season. Their opener against #4
Arkansas propelled them to the top of the polls, where they remained throughout the season. They had help from new head coach
Pepper Rodgers'
UCLA Bruins, who had defeated #1
Nebraska to start the season, led by junior college transfer quarterback
Mark Harmon. The Trojans' closest contest was a defeat of #15
Stanford. In the
UCLA–USC rivalry game with the Rose Bowl on the line for both teams, the Bruins were outmatched by the Trojans USC then soundly defeated
Notre Dame behind the six touchdowns of
Anthony Davis. Quarterbacking duties were shared by
Mike Rae and
Pat Haden. The Trojans were favored by two touchdowns in this the first of three consecutive appearances, all against Ohio State.
Ohio State This was the first year that freshmen were eligible for varsity football in the University Division (now
FBS) due to the NCAA rescinding an earlier rule, and it was the first of four Rose Bowl appearances for freshman
Archie Griffin. Ohio State had one loss at
Michigan State, on November 11. USC had demolished the Spartans only five weeks earlier in a night game at the Coliseum. Against
rival Michigan, the Rose Bowl was on the line for both teams; the Big Ten had rescinded its long-standing "no repeat" rule, so Michigan was eligible to play in the Rose Bowl for a second straight year, and the unbeaten Wolverines were a slight favorite over the Buckeyes in Columbus. However, Ohio State used a defensive goal line stand in the first half and another in the second half to beat #3 Michigan The Buckeyes and Wolverines shared the Big Ten title, and the conference's athletic directors voted to give Ohio State the Rose Bowl bid. Because the Big Ten and Pac-8 did not yet permit teams to play in any postseason game except the Rose Bowl, the Wolverines stayed at home. The two conferences allowed multiple bowl teams starting with the
1975 season. ==Game summary==
