COLUMBUS, Ohio -- Safety Taylor Mays is back in the game for USC, but the Trojans might be a bit concerned about their young quarterback.
Freshman Matt Barkley has been a bit shaky early on, misfiring on five of his first six attempts and throwing an interception to Buckeyes linebacker Ross Homan. Barkley has missed the open man a few times, though he made a nice third-down throw to David Ausberry.
USC is doing a better job of establishing the run game with Joe McKnight and Stafon Johnson, which should take some of the pressure off of Barkley.
