Pullman, Washington, is the site of the Pac-12's most intriguing action this weekend, as Washington State plays host to No. 8 Stanford on Halloween night. An unranked Wazzu team hasn't beaten a top-10 opponent since 1992, when quarterback Drew Bledsoe led the Cougars to a win over No. 5 Washington. That's a streak of 24 games. Elsewhere, two of the league's best quarterbacks face off in Berkeley, California, when Cody Kessler's USC Trojans visit Jared Goff's California Golden Bears. UCLA, meanwhile, is looking for its fourth straight 6-2 start in Jim Mora's tenure when the Bruins host Colorado.
