USC's struggles over the last few years of Pac-12 play don't really apply to the California Bears.
Jeff Tedford's squads, while consistently solid nationally and often a force in the conference, have just not been an issue for the Trojans of late. In 2008, USC shut down Cal's offense entirely and won 17-3. In 2009, the Trojans blew the Bears out, 30-3, in a game dedicated to Stafon Johnson, who had dropped a bench-press bar on his throat in the week leading up to it. And, last year, at the Coliseum, USC led 42-0 at halftime before pulling away with a comfortable 48-14 win.
Going back further, the Trojans haven't lost to Cal since a triple-overtime game in Berkeley in 2003, a game in which future Super Bowl-winner Aaron Rodgers was replaced in the second half becaise of poor play. The 2011 Bears starting signal-caller, Zach Maynard, has been replaced by a backup, Allan Bridgford, twice this season. But those appearances came later in the game, in one case because of an injury and in the other because of a blowout.
Maynard, a Buffalo transfer, has proven to have well-developed chemistry with his top two receivers in Keenan Allen and Marvin Jones. Running back Isi Sofele stepped right in for Shane Vereen, who left to the NFL, but the Bears defense has been the primary issue at fault for the team's 3-2 start.
Cal was 3-0 at first, after a trio of non-conference games. But Keith Price and Washington found a way to beat the Bears last month in Seattle, and then the Bears again struggled to keep up with Oregon last week in Eugene. The latest problem is the pass defense, especially now, with top corner Marc Anthony out for the foreseeable future and a true freshman, Stefan McClure, in for him.
With how much trouble USC's quarterback-receiver tandem of Matt Barkley and Robert Woods has caused some better defenses so far this year, it's not hard to imagine a situation where Woods surpasses 200 receiving yards on Thursday at AT&T Park.
Cal's run defense allowed a ton of yards (239) to Oregon's LaMichael James on Thursday, but that's not indicative of its normal play. Washington running back Chris Polk gained three yards a carry against the Bears in that Huskies win, and Fresno State's Robbie Rouse and Colorado's Rodney Stewart both ran the ball poorly earlier this year, too.
A Marc Tyler-dominated day is not likely for USC in what promises to be an unusual environment at AT&T Park, where only a handful of Trojans have played a football game previously.
A Barkley-to-Woods one is.
