OK, I generally give the coaching staff wide latitude in terms of play calling. We all our subject to lots of cognitive biases that make criticism of playcalling really easy (for example, when we hate a play-call and it goes badly, we remember and attribute the poor outcome to the playcalling, but when we like a play-call and it goes badly, we don't). Plus, Shaw and company have forgotten more football than I will ever know.
However there is one place where I think there is room for fair criticism, because the math has been done on it. And that is punting within the opponent's 40 yard line. The reason is that the value of a possession far exceeds the value of field position on the opponent's half of the field. It doesn't matter too much on the expected number of points whether USC has the ball at their own 7 yard line or their own 32 (or worse, whether they have the ball at their own 20 or their own 29).
Now, in both situations we were at a bit of a quandry. We were facing fourth and long (4th and 22 in the second quarter; 4th and 13 in the fourth), and the field position was such that it might have been a stretch for Williamson to hit, especially if something is going on with either his health, his confidence, or his mechanics that we aren't privy to). Still, there was some finite probability that he would make the field goal, and some finite probability that we could convert a fourth and long (on a small sample size, we were 3/5 throwing on third down and 10+ to go, with 2 first downs, good for a 40% conversion rate; last year we got 11 first downs in 27 chances on 3rd and 10+ to go).
In contrast, the value of 25 and 9 yards of field position was dubious, to say nothing of the psychological benefit to our opponents of knowing they only have to stop us for three downs, rather than four. All in all, I probably would have kicked the field goal from the 29 yard line on 4th and 22, and gone for it on fourth and 13 from the 32.
