Michigan has been in this spot recently. Just not with Jim Harbaugh.
The Wolverines (1-2) are just one loss away from their first 1-3 start in over half a century. That season kicked off in 1967 with Bump Elliott at the helm, and it ended with an uninspired 4-6 record. Elliott lasted one more year in Ann Arbor before a guy named Bo Schembechler took over the reins.
Fast forward 41 years from that 1-3 start and it was Michigan once again on the brink of dropping three of its first four games. It was 2008, and the Rich Rodriguez era was off to a rocky start with convincing losses to Utah and Notre Dame, paired with a lethargic 16-6 win over Miami (OH).
