Oregon's Rise, USC's Fall Reshape Pac-10

PHOENIX (AP) -- The first tremors struck last season with Southern Cal's struggles and the rise of Oregon.

This season there has been an undeniable power shift in the Pac-10.

USC is out of the rankings. The fast-and-furious Ducks have raced up the polls, in position for a national-championship run.

And the rest of the conference, except for maybe one team, has become a tightly packed beat anyone, anytime bunch.

The conference jumbling starts with USC.

The Trojans showed the first dent in the armor a year ago in their last season under Pete Carroll. This season, USC has been hampered by sanctions from the Reggie Bush fiasco and lack of depth caused by players transferring to other schools.
