Max Wittek has a booming arm and big-game experience. Cody Kessler has superior mobility and a level head. Max Browne has limitless potential.

Coach Lane Kiffin has quite a choice on his hands this month when he selects Matt Barkley's successor as Southern California's starting quarterback.

Kiffin insists there's no clear favorite to replace Barkley, the Trojans' four-year starter and the most prolific passer in Pac-12 history.

Instead, training camp features a lively quarterback derby headlined by Wittek and Kessler, who both learned plenty from backing up Barkley last season. Browne is also in the mix after being named the nation's top high school player last season.

All three quarterbacks are eager for the chance to run the Trojans' offense as they seek to erase last season's dismal memories.
