Michigan Wolverines head coach Jim Harbaugh is interviewing for the Minnesota Vikings head coaching vacancy this week.

Jim Harbaugh is interviewing with the Vikings, league source confirms as @ProFootballTalk said. Unclear if this will lead to a deal, but an intriguing name to watch with all of his success with Michigan and the 49ers

The Vikings are looking to replace Mike Zimmer, who was fired after leading the franchise for eight seasons.

I don't know how high Harbaugh is on the Vikings' list, but it wouldn't surprise me if he gets the job. Harbaugh took the San Francisco 49ers to the Super Bowl in 2012. He also took the 49ers to the NFC Championship game in 2011 and 2013.

If Harbaugh leaves Michigan for Minnesota, it'll put the Wolverines in the unenviable position of hiring a head coach in February.

There are a few obvious options that Michigan could consider if Harbaugh lands the Vikings job.

Note: There's no way Cincinnati Bearcats head coach Luke Fickell would take the Michigan job. He's an Ohio State guy through and through.

Matt Campbell — Iowa State head coach

Campbell has managed to find sustained success at Iowa State, a program where it's historically nearly impossible to win. Campbell has resisted offers from NFL teams and marquee college programs in recent years. The Ohio native, however, could be very tempted to take the Michigan job. That's a destination job for a coach like Campbell, who is big on loyalty.

Matt Rhule — Carolina Panthers head coach

News broke last week that Rhule would be interested in the Michigan job if Harbaugh leaves. It's clear that Rhule isn't cut out for the NFL (10-23 in two years). For some reason, the Panthers are bringing Rhule back in 2022. But if the former Baylor coach can get the Michigan job, he'll be out of Charlotte in a heartbeat. Rhule had some nice success at Baylor, and he played college football at Penn State, so he could be a good fit here.

Bill O'Brien — Alabama offensive coordinator

I imagine O'Brien would love to get back to the NFL after serving seven seasons as the Houston Texans' head coach. But it doesn't seem like there's a lot of interest in O'Brien in the NFL (outside of the Jacksonville Jaguars, who interviewed him recently for their head coaching vacancy). O'Brien likely needs to decide on whether or not he wants an NFL offensive coordinator job or a college head coaching job. O'Brien did a good at Penn State in a tough situation, going 15-9 in two seasons. Maybe the Michigan job could be the right fit.

Josh Gattis — Michigan offensive coordinator 

Michigan could always decide to go with an internal hire. If they do, then Gattis would be the guy. Gattis is only 38, but he's quickly built a reputation as a solid football coach. I don't know how the Michigan fan base would react to this hire, but the Wolverines could do a lot worse (Michigan had the No. 16 scoring offense in the nation under Gattis in 2021).
