Carolina-Duke: Four things to watch Posted Feb 19, 2014 It's UNC-Duke on Thursday night. It's two teams vying for what might just be one of the top four spots in the ACC tournament (and the top four spots receive byes for the first two days). Four things to keep an eye on: 1. UNC's perimeter defense vs. Duke's perimeter shooters. Roy Williams knows how well Duke can shoot the ball. The Blue Devils are making 41.6 percent of their three-point shots.
