Only Tarhole fans care when another team loses. You roaches take joy when we lose too another team even when you have lost too that team. Most Duke fans don't care if you lose too another team unless it's in the tourny and ends your season. A regular season game doesn't really give us joy.
I have been watching ACC basketball for a long long time, and Duke and UNC fans love to see each other lose whether its in the NCAA or the YWCA. And Wake/NCSU fans love to see both of them lose. Thats the way it is, and the way it has been since Everett Case started coaching in the ACC.
