I've looked at all the fan made videos and I thought the crew did a fair job, but called holding a little tighter than most Big XII crews (to an extent that I wondered if someone had asked them to concentrate on a particular technique that Texas was prone to using), and made a few mistakes that I thought were reasonable from the angles the covering officials had on the play. There's one holding call the fans are livid about but I think looking at the video that the umpire made a great call of a falling blocker hooking the defender around the legs.
It's an example though of how a couple of weird things, even if called perfectly, will destroy the tenuous trust the unwashed masses have in the stripes. In a short span in the fourth quarter, while the visiting team was mounting its come back, there was a play where a fumble is awarded to the team least likely to have recovered it, a defensive lineman is called for DH about 7 yards ahead of the play, and the head coach is called for USC.
As I said after a similar stretch in a game once, "sometimes you work the game, and sometimes the game works you."
