In 1968 Ohio State defeated the number one-ranked Purdue Boilermakers and continued to an undefeated season including a 50–14 rout of Michigan and a Rose Bowl victory over the USC Trojans that resulted in the national championship. The Class of 1970 became known as the "super sophomores" in 1968, and might have gone on to three consecutive national championships except for what may have been the most bitter loss in Buckeye history. The winning streak reached 22 games as Ohio State traveled to Michigan. The Buckeyes were 17-point favorites but directed by first-year coach Bo Schembechler, Michigan shocked the Buckeyes in a 24–12 upset.
