It's Must Win Week in the Pac-12. A number of teams are playing do-or-die games. WSU against OSU has the feeling of a game that will determine whether or not each teams season is good or mediocre. UW has it's best chance in years to knock off Oregon, and on College Gameday no less. Arizona needs a bounce back win against USC, but who knows how the Trojans will respond to the recent coaching change? Is Utah legit? They've got a chance to prove it against Stanford.
