Cooper Flagg puts a Kansas Jayhawk on a poster with one-handed dunk

Cooper Flagg had a quiet first half against No. 1 Kansas on Tuesday, but he made plenty of noise with a one-handed dunk after the break.

Even when he isn’t stacking 20-point performances, Duke basketball phenom [autotag]Cooper Flagg[/autotag] can’t help but add to his collegiate highlight reel.

Flagg only scored two points before the break against No. 1 Kansas on Tuesday night, only taking two shots from the floor as the Jayhawks double-teamed him constantly.

However, with star center Hunter Dickinson ejected with 10:26 left to play, the star Blue Devil smelled opportunity. With a little more than nine minutes on the clock, Flagg set up a screen for fellow freshman Kon Knueppel to set up a pick-and-roll opportunity.

Knueppel fed the ball back to Flagg as soon as both Kansas defenders broke toward him on the perimeter, and the Maine native had a head of steam with nothing between him and the basket except Jayhawks big man Flory Bidunga.

Flagg didn’t seem overly bothered by Bidunga’s presence. Instead of opting for a contested layup or a short floater, the top-ranked freshman in the country simply slung the ball back with one hand and slammed it home right over Bidunga’s head.

Flagg’s already produced several eye-popping dunks in his debut season, but this one might be his best work yet.
