Michigan coach Jim Harbaugh sparked a little Twitter rivalry with Ohio State athletic director Gene Smith on Tuesday.

The Wolverines have been practicing and holding high school camps in Florida, which has sparked controversy given the recruiting implications of the move.

Smith shot out through the media: “If we were jump starting our program, I’d probably try to do that too.”

And Harbaugh brought up a little Buckeyes history in his retort.
