It’s been less than two months since Ohio State shocked the college football world by upending Oregon in the College Football Playoff National Championship game. The Buckeyes are already back at it. Tuesday was the first day of spring practice for the squad, which will look to defend its title in 2015.Here are some notes, photos and clips from the event. It’s noted that quarterback Braxton Miller was able to do some light throwing, but that Cardale Jones was the only signal-caller able to participate fully. In the background of a few of the videos, you can see the National Champions 2014 banner hanging in the team’s practice facility.Braxton Miller off to the side at Ohio State spring practice throwing a little. Short stuff. Not throwing too hard.— Andy Staples (@Andy_Staples) March 10, 2015Just got out of Ohio State’s first spring practice, where the QB saga continues. Cardale Jones, J.T. Barrett, and Braxton Miller all dressed— Dave Briggs (@DBriggsBlade) March 10, 2015Interesting start of spring for Ohio State. Braxton Miller can run but not throw. JT Barrett can throw but not run. Cardale Jones full go.— Tim May (@TIM_MAYsports) March 10, 2015pic.twitter.com/y7mJ06XXT4— Urban Meyer (@OSUCoachMeyer) March 10, 2015The CHAMPS are here! #GoBucks pic.twitter.com/3S2IzDKHW2— Ohio State Buckeyes (@OhioStAthletics) March 10, 2015Safety Dance!
