Bit of an overreaction, don't you think? You don't think that they can get eight wins from Western Michigan, South Dakota, Purdue, Rutgers, Northwestern, Iowa, Nebraska, and Minnesota? If you watched USC towards the end of the season you would know that they are nothing to fear - they gave up 41 to Colorado, 41 to Arizona, 48 to Notre Dame, 34 to Utah, 49 to Cal(!), 52 to Washington, 36 to Oregon, and 38 to UCLA and lost 5 of their last 6. They're losing Williams to the NFL and at last check had 15 players in the transfer portal including a 5-star freshman QB.
The remaining three are really tough but they are all at home. Last time they played Oregon they should have beat them in the 2019 Rose Bowl if it wasn't for a botched punt and a bad pass interference call.
