HOLLYWOOD - Amid all the customary, late-July optimism flying around Paramount Studios on Wednesday, at least one Pac-12 football coach struck a candid, realistic tone. The Bears are still young, they're still adapting to new defensive coaches and they still face one of the country's most daunting schedules - plus Sandy Barbour, the athletic director who hired Dykes, was pushed out of her job and departed last week. Michael Williams, a former Cal wrestler, replaced Barbour as interim athletic director July 15 but has no interest in taking the job permanently. Williams insisted otherwise, saying he's building a relationship with Dykes and realizes the coach walked into a difficult situation, given modest talent and abundant injuries. Cal was way beyond awful last season - the Bears ranked 122nd out of 123 FBS teams in total defense (529.6 yards per game) and scoring defense (45.9 points per game). Dykes, whose personal history is on offense, said the Bears will feature multiple defensive looks, using both the 4-3 and 3-4 alignments. Quarterback Jared Goff passed for 3,508 yards and 18 touchdowns as a true freshman, but Cal struggled to generate a steady running game and repeatedly stumbled inside the red zone.
