In 2006 the USC Trojans went to Reser Stadium to play Oregon State. The Beavers jumped out to an early lead and were able to stop a game-tying two-point conversion with no time left. The Beavers were on the better end of one of the biggest upsets that year.
In 2007, history repeated itself when Stanford was able to go into the Coliseum and beat the Trojans in another great upset of this decade.
Now that another season is right around the corner, we can't help but ponder who could be this year's unseen obstacle for the six-time defending conference champs.
The Arizona Wildcats are who I believe will be the ones to take down Southern Cal this year.
Willie Tuitama leads a spread out run 'n gun offense that the Trojans' traditional-style defense will have trouble keeping up with. Tuitama is my prediction to be this year's breakout Pac-10 player, and he is poised to do so when USC travels to play the Wildcats.
The USC vs. Arizona game is surrounded by two easier games for USC—trips to Pullman and to Seattle to play the Cougars and Huskies.
With the Trojans letting their guard down after putting a beatdown on Washington State, the Arizona Wildcats will have a great chance to be the "David" to USC's "Goliath."
