North Carolina isn't an underdog very often and hasn't been a double-digit dog in a long time. They beat UCLA this season as a dog, 76-74, and beat Duke back in March, 84-79, as a +4.5 dog. The offense is second in the ACC in scoring (81.7 points per game) and fourth in shooting, while the defense is sixth in the 18-team conference in shooting allowed (.424). Duke is on a 2-3 spread run, failing to cover its last two games as double-digit favorites in wins over Wake Forest (63-56) and North Carolina State (74-64). Look for a big effort by both teams in this longtime rivalry and back the big dog. Play North Carolina.
