Big moves on USC's depth chart

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.

And that's not all.

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.

Woods, widely regarded as the nation's top high school receiver last year, will start opposite senior Ronald Johnson. He's eclipsed sophomore Brice Butler for the starting nod.

Robey has beaten out redshirt freshman Torin Harris.
