When the USC Trojans take the field for their annual spring game Saturday, all eyes will be on the program's offense.
The Trojans originally employed Kliff Kingsbury to revamp their offense, but after he left to become head coach of the NFL's Arizona Cardinals, they called upon another disciple of the Air Raid system in Graham Harrell.
Harrell is tasked with improving an offensive unit from a 5-7 team that has some solid returning pieces in quarterback JT Daniels and wide receiver Amon-Ra St. Brown.
Daniels will be under the microscope Saturday since he's one of four quarterbacks fighting for the starting job in Harrell's first year as offensive coordinator.
