Michigan head coach Jim Harbaugh has been stirring up SEC trouble since last Spring, but it’s gotten especially intense in the last month.

Harbaugh is holding part of Michigan’s spring practice at IMG Academy in Florida, and the SEC has taken offense to that.

So Harbaugh went to war with SEC coaches and the SEC Commissioner Greg Sankey, and Twitter has been the primary battleground.

Here’s a look at the timeline:

After Sankey asked the NCAA to prohibit Harbaugh’s spring practices in Florida, Harbaugh sent out a subtweet presumed to be in response.

But his taunting didn’t stop there.

It’s not just the SEC having a difficult time swallowing Harbaugh’s antics. The NCAA President Mark Emmert expressed his personal opinion and displeasure with Harbaugh.

“There’s a difference between not being prohibited and being OK,” Emmert said.

On February 19, Harbaugh dismissed complaints made by Sankey as well as Sankey himself.

“I guess [Sankey] is stating a case, but it doesn’t hold water to me,” Harbaugh said. “I think there’s been some humor about it. I think it’s comical that he’s taken exception to it.”

On February 22, Georgia head coach Kirby Smart told the Macon Touchdown Club he disagreed with Harbaugh’s spring practice decisions.

“I can’t comment other than to say they’re obviously trying to gain a competitive advantage,” Smart said. “That’s their right but I think the NCAA, in due time, will have to step in and keep it from getting out of hand.”

Then Harbaugh posted this…

Harbaugh “finally” responded to Smart.

But other coaches were already jumping on board with Arkansas head coach Bret Bielema.

Harbaugh couldn’t resist dragging Tennessee through the mud.

The NCAA blocked Bielema from attending the IMG open practice.

Ole Miss head coach Hugh Freeze also requested to attend the practice.

ESPN analyst Kirk Herbstreit seems to be sick of Harbaugh’s drama, and he wants him to take it to the field.

Will Harbaugh step up and take this battle off the Internet and onto the gridiron?
