The game was effectively decided in the second quarter. The Heels dominated possession early, largely on the back of winning 12-of-16 first half face-offs, parlaying that advantage into a 22-4 shot edge in the second quarter, when they turned a 4-3 Duke lead at the end of the first quarter into a 10-4 Tar Heel lead at halftime. They picked up 13 groundballs in the second period to Duke’s one.
