Will Jim Harbaugh's Big Personality Overshadow Michigan Football in 2015?

This isn't exactly breaking news, but Jim Harbaugh has a big personality.

Need proof? Look no further than the new Michigan head coach's Twitter account.

Yes, while other head coaches use their Twitter accounts purely as a promotional tool—such as Harbaugh's Ohio State counterpart, Urban Meyer—the Wolverines head man has opted to put a personal twist on his return to Ann Arbor. Tweeting almost daily, it's not uncommon for Harbaugh to uniquely wish his players happy birthday, share his thoughts on historic anniversaries and post pictures of himself among other members of the Michigan elite.

He's even (allegedly) subtweeted Meyer. And Harbaugh's ability to create headlines hasn't been limited to 140 characters or fewer either.

Since accepting the Wolverines' head coaching job at the end of December, Harbaugh has become college football's most meme-worthy coach. Whether it's eating pizza courtside at a basketball game, tutoring NFL prospects Jameis Winston and Bryce Petty or unintentionally going face-to-face with Tom Izzo, the former 49ers head coach has shown an uncanny ability to go viral on a consistent basis.

Even his introductory press conference with the Wolverines made waves on the web.

“I don’t know if anyone saw me trip on the way in,” Harbaugh said as he laughed off his stumble. "A lesser athlete would've gone down."

Harbaugh's bold personality is apparent in everything he does and appears to be one of Michigan's greatest assets moving forward. But with his first spring football at the helm of his alma mater kicking off Tuesday, his Twitter presence will take a backseat, the happenings on the gridiron taking precedent.

Make no mistake, Harbaugh's personality isn't going anywhere—it's just as evident on the sideline as it is online. But once the Wolverines are finally on the football field, what kind of effect will it have?

For all of the positive public relations Michigan has enjoyed since Harbaugh's hiring—including a likely much-needed boost in ticket sales—the Wolverines are yet to prove they're anything more than a mediocre football team. Last season, Michigan endured a 5-7 campaign under Brady Hoke, and with only one month on the recruiting trail before signing day, Harbaugh only managed to add the nation's 38th-ranked recruiting class to his roster.

The revitalized Wolverines fanbase is embracing Harbaugh's tweets right now, but how will it receive them if Michigan's struggles continue in 2015?

One precedent worth examining is Arkansas coach Bret Bielema, another social media-active coach who has only accumulated a combined 10-15 record in his first two seasons in Fayetteville. Bielema seemingly racked up Twitter miscues as quickly as he did losses with the Razorbacks, which made him an easy target for the college football blogosphere.

Being the butt of jokes hasn't affected Bielema's job security, however, with Arkansas recently extending his contract through 2020. The former Wisconsin coach also doesn't have a track record that matches that of Harbaugh, who took the 49ers to three consecutive NFC Championship Games and a Super Bowl in his first three seasons in the NFL.

He may not have been on Twitter then, but the former Pro Bowl quarterback's personality was just as apparent during his time in the Bay Area. Even without a social media platform of his own, Harbaugh still managed to make viral headlines with stories about his wardrobe, facial expressions and offseason activities.

In fact, one could argue that Harbaugh's intensity and uniqueness have been the primary forces behind his success. And neither has prevented him from completing a turnaround as a head coach before.

When Harbaugh took over Stanford in 2007, the Cardinal were coming off a 1-11 season. In each of his four seasons at Stanford, Harbaugh managed to increase the team's win total, culminating with a 12-1 Orange Bowl-winning campaign in 2010.

That was the same year the 49ers went just 6-10 despite possessing one of the more talented rosters in the NFL. San Francisco opted to turn to Harbaugh when hiring a new head coach in the offseason, beating out the Miami Dolphins, who were also vying for his services.

The Toledo, Ohio, native's time in the pro ranks was hardly a disappointment, as he amassed back-to-back NFC West championships in his first two years on the job and a third straight trip to the conference title game in 2013. A clash of personalities with San Francisco management had more to do with his departure than performance, which shouldn't be an issue in his return to Ann Arbor.

Because for the first time since Lloyd Carr left the Wolverines following the 2007 season, Michigan is finally united behind a single leader. But with a roster still left with much to prove on the field, only time will tell whether Harbaugh's strong personality will be a uniting or dividing force in Ann Arbor.

But make no mistake, when the Wolverines take the field for their first spring practice under Harbaugh on Tuesday, his attitude will be evident.
