Duke basketball and UNC played a thriller in the ACC Tournament at Spectrum Center. Here are the observations.

In the wake of Flagg's absence, freshman Kon Knueppel took over. The Duke star posted 18 points, eight rebounds and three assists in the ACC final against Louisville. As Knueppel prepares for his first March Madness appearance, he took to social media, sharing some exciting NIL news.

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.
