There's not much to write about here. On any given day, any team can beat any other team... and did today. Although Stanford certainly looked much better with their backup quarterback taking over, USC looked terrible all around. Booty's passing game has regressed, and the offense was sloppy all around, allowing 5 turnovers. Even the defense looked weak.
If there's anything good about this, it's that the team will be forced to take its practice and preparation much more seriously.
