Michigan Wolverines Head Coach Jim Harbaugh has said, he has unfinished business with the NFL. He tried to get the Minnesota Vikings Head Coaching job last February.
Michigan is destined to headline the College Football Playoff after an undefeated season under the leadership of Harbaugh. Based on the latest report from NFL insiders Ian Rapoport and Tom Pelissero, the interest is very much real to bring in former San Francisco 49ers coach Jim Harbaugh back to an NFL sideline.

Sources say multiple NFL teams have been doing background work recently on Harbaugh, who led Michigan to the Big Ten championship and locked up a College Football Playoff bid with Saturday’s 43-22 win over Purdue.
There’s belief that Jim Harbaugh would at least entertain such discussions to return to the NFL, once the Michigan football season wraps up.
One NFL source plugged into the situation said they believe Harbaugh would consider a return to the NFL, and a source with another team that could be running a head-coaching search said they believe Harbaugh would discuss an opening if asked and weigh the right situation.
