Technically, he's the innaugural winner of the Thompson-Randle El Freshman of the Year trophy (named for Minnesota's Darrell Thompson and Indiana's Antwaan Randle El):
A two-time Big Ten Freshman of the Week honoree, Miller is the seventh Ohio State player to take home the conference’s Freshman of the Year accolade. The quarterback played in 11 games for the Buckeyes and started the team’s last nine games. Miller finished the regular season ranked among the conference’s top 10 in total offense with 11 passing and seven rushing touchdowns to go with 1,692 total yards.
Miller didn't earn his first start until week four when he led the Buckeyes to a 37-17 victory over Colorado and would go on to lead the team in passing as well as rushing with 695 yards on the ground.
Now just imagine what he's going to do next year in Urban Meyer's offense.
