WINSTON SALEM - Good teams play well when they need to. During much of the season, the North Carolina volleyball team played like it was fighting itself. While the Tar Heels usually outplayed their opponents, UNC couldn't always finish them off. Mental mistakes and a lack of focus made some of North Carolina's regular-season matches closer than they should have been. But that wasn't the case this past weekend. The Tar Heels entered the ACC tournament seeded No. 2 and left as conference champions.
