If any team would be prepared for an opener in normal circumstances, it is Cal. Eighteen starters are back for the Golden Bears. But these are unusual times. They practiced all week with no expectation of playing after two cancellations until this game was jury-rigged Friday afternoon. Complicating matters, they must pack quickly to travel. UCLA practiced toward a game — albeit with a different foe — and improved significantly between the start and finish of its opener. Series trends support UCLA: Underdogs have won four straight and home teams seven of the past 10.
