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.

Flagg and Duke had their toughest test yet Tuesday night against No. 1 ranked Kansas, where they came up just short and fell 75-72. Flagg had 13 points, five rebounds and three assists, but his highlight of the night was a massive slam dunk over Kansas' Flory Bidunga.

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.
