I am a USC fan, but I agree that they are overrated this year. They have lost too much talent the past two years to the NFL. This year's team has great potential, but isn't ready yet.
I am not worried about this Saturday---the Trojans should beat the Huskies easily. But I really doubt USC will make it to the BCS championship game. Cal has an excellent chance to beat them. Even UCLA could do it, based on pure emotion if nothing else. I agree with DodgerKing. USC prepares well for top-rated teams and often just tries to mail in games against "inferior" opponents.
Cal is very inconsistent. Cal plays USC at home this year. If they are "on" they will win. If they are "off", USC will kill them. I am betting they will be "on".
