I have watched the first three minutes of the USC(west coast) vs CSUN game and will state that USC will have the worst team in the Pac 12, and I havent seen all of the teams yet.
USC started four freshmen with Caldwell. Caldwell was the only player on the court who was with the team last year. They also played a walk-on, India Otto from the same high school as Jordin Canada and Charisma Osbourne. A lot of minutes went to the unranked Alison Miura. Alissa Pili got a double double (18 pnts, 13 rebounds). The only other player with college experience was Stephanie Watts and she has been recovering from injury in the fall.
With the cast, I didn't think it was a bad showing at all. I would absolutely take that bet that USC is the worst Pac team.
