North Carolina's furious comeback against Duke in the ACC Tournament semifinals came up short after Jae'lyn Withers committed a lane violation on teammate Ven-Allen Lubin's successful second free throw attempt — which had it counted, would've tied the game at 72 with seconds remaining.

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

The best option to stop Knueppel is to put fellow freshman Drake Powell on him. Powell did a great job on Flagg for most of the game in Chapel Hill, and if Flagg sits, he'll be freed up to target Duke's new top offensive option.
