TUCSON, Ariz. (AP) - Arizona and Southern California put on an offensive show in the Coliseum last season, combining for over 1,100 yards of offense.

There's no reason to think they won't do it again in the desert on Saturday.

The 10th-ranked Trojans have many of their skill players back from last season, including quarterback Matt Barkley and receivers Marqise Lee and Robert Woods.

USC leads the Pac-12 South after rolling over Colorado 50-6 last week.

Arizona has a new coach and a new quarterback, but is more prolific than last year, ranking fifth nationally in total offense with 548 yards per game. The Wildcats are coming off a 52-17 rout of Washington last week that ended a three-game losing streak.
