Seth Curry kept burying shots against helpless North Carolina defenders to give No. 3 Duke a big lead, then Mason Plumlee dominated inside to keep the Blue Devils in complete control against their fiercest rival. This performance was about more than just beating up the Tar Heels. It was the Blue Devils showing they're determined to play their best in March. Curry hit his first seven shots during Duke's torrid start, helping the Blue Devils cruise to a 69-53 victory Saturday night in a game that was never in doubt.
