Jim Harbaugh hasn't had much success at Michigan, which could lead him to rejoin his brother in the NFL. With his tenure in Michigan likely coming to an end after this season, Harbaugh is eyeing a return to the NFL, per Mike Florio of ProFootballTalk.

For the past six years, Harbaugh has been the head-man in Michigan, with many believing he would turn around the program. However, while he's posted three double-digit win seasons, Harbaugh's team has posted an abysmal 1-4 record in bowl games.

Not to mention, this season, Michigan currently holds a 2-4 record, losing to Michigan State, Indiana, Wisconsin, and Penn State. Seeing that he's had plenty of time to leave his imprint on the program, he could very well be looking for a new job after the college football season concludes.

Of course, before he joined Michigan, Harbaugh had a ton of success as the head coach of the San Francisco 49ers. Harbaugh would coach the 49ers from 2011-2014, posting an impressive 44-19-1 record. He also helped lead San Francisco to the Super Bowl in 2012, facing his brother, John Harbaugh, and the Baltimore Ravens.

With Colin Kaepernick as his quarterback and a dominant defense, Harbaugh won 36 games in his first three years in the Bay Area. But in his fourth season, the 49ers would finish at 8-8, leading them to move on from the charismatic coach.

There are plenty of job openings in the NFL, with teams like the Detroit Lions, Houston Texans, Atlanta Falcons, and likely others needing new head coaches. Even though things didn't pan out at Michigan, Jim Harbaugh could look to get another chance to coach in the NFL.
