Duke basketball's Cooper Flagg wasn't pleased with his first half against N.C. State, and neither was Jon Scheyer. Here's what changed.

After a so-so first half, Duke's Cooper Flagg posted 23 second-half points and added five rebounds, an emphatic block and two assists during the Blue Devils' rousing 74-64 victory over the NC State Wolfpack on Monday night at Cameron Indoor Stadium.

Flag scored 23 of his game-high 28 points in the second half to power the Blue Devils past the Wolfpack 74-64 to improve to 18-2 and 10-0 in ACC play. Duke outscored NC State by 14 in the second half thanks largely to the play of Flagg and fellow freshman phenom Kon Knueppel, who added 19 points of his own.
