Cooper Flagg is one of the most hyped rookies in NBA history after being the top selection in the 2025 NBA Draft. He had an outstanding one-and-done campaign with the Duke Blue Devils in which he led his team to the Final Four, along with winning National Player of the Year as a true freshman.

Dallas Mavericks rookie wing Cooper Flagg wasted no time making his mark at the NBA Summer League—putting his versatile skillset on full display and proving exactly why he was the No. 1 overall pick in the 2025 NBA Draft.

Flagg was the No. 1 player in the class of 2024, per 247Sports' composite rankings, and he was widely projected to be the first pick in the 2025 draft even before he stepped foot on campus last year. His play in his lone season at Duke all but confirmed that he was the best player in this year's draft class.
