How bad was the loss for UNC, and Mack Brown, to Duke at Wallace Wade Stadium?

Andrew Carter, News and Observer, was at the Duke vs UNC game and discusses what he saw in Durham, as well as the post game press conferences. 

What happened at Wallace Wade Stadium this past Saturday? How was this game for UNC against Duke “worse” than the JMU loss the week before? What does this game magnify for UNC, in Andrew’s opinion?
