TUCSON, Ariz. -- The relief Cal felt from getting away from Nevada's pistol offense probably didn't last more than 24 hours, when the Bears coaching staff flipped on the tape of Arizona's balanced spread offense and realized they would have their hands full again this week.

The Bears undoubtedly are thrilled they don't have to face Nevada quarterback Colin Kaepernick and the nation's top-ranked offense again. But today's opponent presents a whole new list of problems, from stopping quarterback Nick Foles and Arizona's quick-strike passing attack to finding a way to contain its competent running game at the same time.

The Wildcats, coming off a program-changing win over then-No. 9 Iowa last week to move up to No. 14 in the AP Top 25, are scoring an average of 42.3 points per game, good for 13th in the country. Their passing attack (330.3 ypg) ranks sixth nationally.

And while the Wildcats' rushing attack ranks just eighth in the Pac-10 (127.3 ypg), they haven't really needed the ground production so far. But the Bears are well aware of the damage Arizona's tailbacks -- Nic Grigsby, Keola Antolin and Greg Nwoko -- can do.

"Arizona probably does as good a job of anyone of being able to line up and run downhill at you, and then being able to spread you out and throw it," Cal coach Jeff Tedford said. "They're not one-dimensional by any means."

Cal's defense is eager to get back on to the field to atone for last week's nightmare. The Bears, who are making more of a focused effort this year to get pressure on the quarterback, are aware that will be a tough task against Foles.

The Bears held the Wildcats offense in check last year during a 24-16 victory. But much has changed since last November. Arizona has new co-offensive coordinators while Cal has a new defensive coordinator.
