Now Braxton Miller is getting in on the act.
The former Ohio State quarterback / receiver kept the Michigan-Ohio State Twitter war going Wednesday when he posted a tweet that showed photos of Urban Meyer and Jim Harbaugh side-by-side.
Meyer is holding the crystal football from the 2014 national championship trophy aloft. In a similar position, a shirtless Harbaugh is holding a football from his stop at the high school camp in Prattville, Alabama, last summer.
Miller is expected to be selected in the NFL draft next month.
Your turn, Coach Harbaugh.
