North Carolina needed four clutch free throws from Marcus Paige to fend off a late charge from the Duke Blue Devils in Cameron Indoor Stadium Saturday, but the Tar Heels held on to win their 30th regular-season ACC title.

North Carolina coach Roy Williams has struggled against Duke (UNC has won just four of the last 15) and was widely criticized after UNC's stunning home loss to the Blue Devils earlier this year, so this postgame dab in the locker room probably felt extra satisfying.

This isn't the first time Williams has dabbed after a win.
