Washington ranks 329th in scoring averaging 61.7 points. California isn't that much better ranking 271st in scoring at 67.6 points. 
This total, though, has come higher than expected, probably based in part on Washington giving up 91 points in a 16-point loss to Stanford two days ago. That was an aberration. No not that Washington lost. The Huskies are 1-8. But that the Huskies surrendered so many points because they usually can be counted on for good defense under Mike Hopkins, who brought a matchup zone defense with him from Syracuse where he was an assistant for 22 years. 
The Huskies could catch a break because Cal's leading scorer Matt Bradley hasn't played since Jan. 2 due to an ankle injury. Bradley averages 17.8 points. 
California's defense is respectable, giving up 68.2 points a game. The Bears are not up-tempo so that's another plus for the Under.
