Rookie sensations aren't supposed to dominate the jersey sales charts, but Cooper Flagg is rewriting the rules. The former Duke star and Wooden Award winner didn't just have a stellar first year with the Dallas Mavericks; he captured the imagination of the basketball world, finishing the 2025-26 season with a top-10 jersey.

Flagg's immediate impact was undeniable, highlighted by a jaw-dropping 51-point game and shattering rookie records once held by LeBron James. This on-court brilliance, combined with a massive fanbase built during his collegiate days, propelled his jersey to the ninth spot in sales—a remarkable feat that placed him ahead of established superstars and former MVPs like Nikola Jokic and Kevin Durant.

His success also marks a proud moment for Duke basketball, as he joined Celtics star Jayson Tatum (seventh) to give the Blue Devils two alumni in the top 10. Flagg's rookie year wasn't just about stats; it was the birth of a new must-have jersey in the NBA landscape.
