We didn't rank these coaches, because there would be no real drama in who was No. 1 on the list. In just over a year on the job, Jim Harbaugh has not only revitalized Michigan's football team but also firmly established himself as the king of social media among his peers.
And it's not even close.
In addition to being seemingly everywhere—WWE matches, golf tournaments, spring training games—while still remaining focused on the Wolverines' offseason workouts, Harbaugh maintains a constant presence online. His tweets include all the usual stuff you'd expect from a coach, including GPA updates and the welcoming of new recruits, as well as fun updates of his overseas trips or his obsession with Judge Judy, but those serve as the complimentary breadsticks before the real meal is served.
That is where Harbaugh reigns supreme, without any close competition. His mastery of subtweeting (which might as well be called Harbaughing at this point) was most recently on display when he threw shade toward Ohio State athletic director Gene Smith in response to Smith's comments about Harbaugh holding spring practice in Florida.
Retweeted or liked more than 15,000 times, this veiled dig finds itself atop Sports Illustrated's list of the top Harbaugh Twitter feuds. Yes, he has an entire list all to himself, which says all you need to know about Harbaugh's social media wizardry.
