Big leads haven't been entirely safe when Duke and North Carolina State get together at Cameron Indoor Stadium. So even as the Blue Devils went up by 21 points, Mason Plumlee knew the Wolfpack would rally somehow. "They're too good not to," Plumlee said. And No. 4 Duke was too good to let its lead slip away. Plumlee scored 30 points in the Blue Devils' 98-85 victory Thursday night.
