Flagg has been tested during the first weeks of his college career, and the 17-year-old phenom still looks like the No. 1 pick in the 2025 NBA draft.

On that play, Flagg drove to the basket on big man Hunter Dickinson. Adams arrived to help and swatted Flagg’s shot. He tried to recover the ball but knocked it out of bounds. On the next Duke possession, Adams stopped a three-on-one fast break by swatting Kon Knueppel’s shot at the rim.

The tone of the game changed when Dickinson kicked Duke's Maliq Brown in the head after they fell to the floor during a fight for a rebound. But Kansas hung on for the win.
