While the focus will undoubtedly skew toward Duke — with or without Cooper Flagg — UNC, Clemson and Louisville are coming off thrilling finishes in their own quarterfinals.

Kon Knueppel scored 17 points and No. 1 Duke held off a furious second half rally by rival North Carolina to beat the Tar Heels for the third time this season, 74-71 on Friday night to reach the Atlantic Coast Conference Tournament championship game.

North Carolina forward Jae'Lyn Withers committed a lane violation with 4.1 seconds left that negated a tying free throw in the Tar Heels' loss to No. 1 Duke in the ACC Tournament.
