Five Storylines: USC-Arizona 

October, 25, 2012
The five key storylines as No. 9 USC (6-1 overall, 4-1 Pac 12) takes on Arizona (4-3, 1-3) in a Pac-12 showdown.

1. USC defense vs. Arizona spread offense: On paper, this will be the toughest offensive opponent the Trojans have faced this year. The Wildcats have taken quickly to new head coach Rich Rodriguez’s hurry-up spread offense and the results have been impressive, with almost 550 total yards of offense per game. It will be up to the Trojans' swarming and attacking defense to pressure the quarterback and look for turnovers or stops.

2. Arizona QB Matt Scott vs. USC cornerbacks: To break down the previous point even further, the key battle within the battle will be Scott throwing the ball against a USC cornerback position that has been in flux. Nickell Robey has been solid on one side, but there has been a rotation opposite him, with either Torin Harris or Josh Shaw appearing to be the primary options. The Trojans will probably need both against the quick pace of the Wildcats offense.
