Cal won the NCAA championship last season.Salo said that although he is confident he knows that beating the bay area teams will be tough.“We are a better championship meet team because we don’t have the depth [they do],” Salo said. “To win either of the meets we will need to score wins in most of the events.”Though the women’s teams will be taking to the pool this weekend, the men have a break from action. They will face Cal and Stanford the following weekend.The contests against Cal and Stanford start the home stretch for USC, as the Pac-12 championship begins Feb. 22, followed by the NCAA championships, which begin in March.
