One year ago, Michigan fans might have been ready to run Jim Harbaugh out of Ann Arbor. Now – after a B1G Championship and College Football Playoff appearance – fans may be eager to try and hang onto Harbaugh.

Harbaugh’s turnaround of the Wolverines makes Tuesday’s report that he could become interested in an NFL job all the more interesting. According to that report, Harbaugh would particularly be interested in the head coaching job of the Las Vegas Raiders.

Now, ESPN’s Adam Rittenberg has shed some light on who might be on Michigan’s radar if Harbaugh were to head to the NFL. According to Rittenberg, Alabama OC and ex-Penn State head coach Bill O’Brien is a name that would generate some buzz for the Wolverines. The internal options of Josh Gattis and Mike Hart would also be expected to draw some attention.

For now, nothing appears to be imminent with Harbaugh, and there have been rumblings of a potential NFL return shot down in the past. It will be interesting to see where this story goes moving forward.
