Lane Kiffin isn't afraid to shake things up. Just consider what appears to be happening on USC's depth chart.
It appears that sophomore Devon Kennard has beaten out junior Chris Galippo, a returning starter, at middle linebacker. It was one of the hottest competitions of spring practices and fall camp after Kennard was moved from outside linebacker to challenge Galippo, who started strongly in 2009 but faded late.
Junior Marc Tyler, a hyped recruit in 2006 whose career has been riddled by injuries, is running as the first-team tailback. Further, two freshmen -- receiver Robert Woods and cornerback Nickell Robey -- also appear to have won starting jobs.
The official depth chart in advance of the opener at Hawaii on Sept. 2 won't be released until Saturday.
Tyler's ascension is due in part to senior Allen Bradford, No. 1 at tailback after spring practices, missing action with a bruised knee. Bradford has returned to practice, so the situation may be a 1A and 1B at this point.
Robey has beaten out redshirt freshman Torin Harris.
