The freshman had season-highs of 20 points and 12 rebounds to help the Tar Heels beat the Wolfpack 76-69 on Sunday, marking the third straight season UNC has upended a top-10 N.C. State team. And N.C. State shot the ball poorly until well into the third quarter after UNC had gained confidence early. N.C. State got no closer than four the rest of the way. And it gave N.C. State at least a claim to the top spot in Monday's next poll. UNC: The Tar Heels' game at Boston College for Thursday has been postponed, meaning UNC's next scheduled game comes next Sunday at Pittsburgh.
