* USC (7-7, 2-2 Pacific 10) at No. 16 ARIZONA (14-3, 3-2), 1 PST, Fox Sports Net--USC will face a good team being prodded by an angry coach. Arizona Coach Joan Bonvicini, after Thursday's loss to UCLA, growled about "character" and challenged her inside players, shut down by UCLA. "Our post players played like they didn't want the ball," she said, and called the USC game "huge." USC Coach Chris Gobrecht sounded much the same after last weekend's 20-point loss at UCLA, and since then the Trojans logged in an overtime loss to Arizona State Thursday. USC got 17 points from senior guard Erica Mashia and the Trojans were five for eight on three-point shots. But they also had 23 turnovers, 10 by Mashia.
