Area of need: Defense
Current situation: We'll be more general with California's situation. The Golden Bears' problem throughout the entirety of Sonny Dykes' four-year tenure -- he was fired Sunday -- was defense. Scoring has not been a problem for Cal, even after losing star quarterback Jared Goff and the top six receivers following the 2015 season. The Bears actually led the Pac-12 in yards per game and scored 37.1 points per game in 2016.
The story on the other side of the ball was markedly different. A year after fielding a legitimately bad defense, Cal rolled out an atrocious one this past season.
