40% chance of victory against Clemson? Not this year. While winning the game isn't impossible, it's going to take a lot of things to fall our way for the upset to happen. We have to play a nearly perfect game, and Clemson has to be flat, and the odds of that happening simply aren't very good at all. A lot can happen during the spring, though.
Also, USC is going to be better than it was in 2019. Regardless of who wins the QB battle (Slovis or Daniels), they're going to have a top notch QB, and a deadly arsenal of skill position people.
