Position switches key in success of USC D

The 2013 USC defense is banking on at least three position changes and probably a fourth in hopes of plugging a unit that had so many holes last season that even the Little Dutch Boy wouldn’t have enough fingers to stop the gushers.

It has been well-chronicled how dysfunctional the Trojans defense was last year. The number of points in games surrendered to the likes of Oregon (62), Arizona (39), UCLA (38), and even Syracuse (29) was enough to even make an onion cry, let alone USC fans.
