Will Jim Harbaugh head back to the NFL?
Jim Harbaugh's time at Michigan has been marred by his unimpressive record against the Wolverines two biggest rivals, Ohio State and Michigan State.
After a sub-par (for Michigan) 8-4 season, some believe he could bolt the university should the NFL come calling.
ESPN NFL analyst Mike Wells brought up several names for the Indianapolis Colts' impeding head coaching vacancy, and Harbaugh was at the top of the list.
He spent four seasons as coach of the San Francisco 49ers and led them to a Super Bowl appearance. Harbaugh knows Luck well after coaching him at Stanford, and familiarity with Luck would help if the quarterback is adjusting to another offensive coordinator.
Harbaugh, who played four seasons at quarterback in Indianapolis, is also the type of flashy name who would draw Irsay's attention.
Despite his possible desire to prove himself once again at the NFL level, landing 5-star quarterback transfer Shea Patterson could keep Harbaugh at Michigan.
