Harrison Barnes scored 26 points as North Carolina dominated Boston College 106-74 on Tuesday night.

Reggie Bullock hit four three-pointers in a 2 1/2-minute span to help lead the Tar Heels.

"The biggest difference for me in the game was Reggie Bullock off the bench," coach Roy Williams said. "We were down five points and then Reggie hits four 3s. The last game, [he] didn't make a field goal. I talked to him after the game and said, 'You probably won't do that again.' "

Joe Trapani had a season-high 25 points and a career-high 15 rebounds for Boston College.
