I would say the jury is still out on them, as it is on many, many teams. Your narrative strikes me as one for which supporting data are lacking. But when you say “not very good,” do you mean not a top 25 team? Not in the top 50? Outside the top 100?
USC led OSU by 18 at the half, and then OSU outscored them 30-10 in 3Q to take the lead. So if in fact Watkins “caught them by surprise,” the surprise seems to have been dispelled by the second half. Nonetheless, USC recovered to win by 9.
I did notice USC very narrowly beat Penn State in the Bahamas, but Penn State also took Ohio State to overtime at Columbus. Hard to know what to make of these scant, often disparate, data points.
Watkins is clearly the breakout star, but I also wouldn't sleep on players like Rayah Marshall, McKenzie Forbes, and Kayla Padilla. We won't have to wonder about USC much longer, as they'll play UCLA twice in their first 4 conference games, and then they travel to Utah and Colorado after that.
