True rivalries have turf and people. Anybody who has lived in North Carolina and paid attention to college basketball knows there are not many Duke fans living in that state. Definitely not in proportion to any rivalry as perceived through the national media. The local rivalry in North Carolina is the Pack and holes. The vast majority of the in-state basketball followers side among these two. The VAST majority. Nationally, Duke has a following to make a rivalry presentable. Locally, it barely exists. Compared to the local rivalry between unc and State, it doesn't.
