The fact that Nebraska got their butts whooped in the 4th quarter shows very little; Nebraska's offense is not built to be successful in obvious passing situations. You're crazy if you think SoCar outplayed Nebraska in the first half, when both teams were allowed to do what they wanted offensively. The c$%ks were on the lucky side of 10 points which drastically changed the way the game was played. I would consider those 10 points to be outliers
Carolina did win the game, but saying they're a much better team than Nebraska is probably a stretch. The reason Nebraska was playing catch-up in the fourth quarter was primarily due to outlier events, rather than the play of the c$%ks.
