Flagg Crowned NBA Rookie of the Year After Dominant First Season with Celtics

Boston Celtics rookie Cooper Flagg has been named the NBA Rookie of the Year for the 2025-26 season, capping off a remarkable first year in the league that exceeded all expectations. The 19-year-old Maine native, selected second overall in last year's draft, demonstrated the versatility and basketball IQ that made him the most coveted prospect of his class.

Watch the highlights:

Flagg's statistics tell only part of the story of his stellar rookie campaign. He averaged 18.3 points, 7.2 rebounds, 2.1 assists, and 1.4 blocks per game while shooting an impressive 47% from the field and 38% from three-point range. His defensive instincts were particularly noteworthy, with several opposing coaches点名表扬 his ability to guard multiple positions and disrupt opponents' offensive sets.

"Cooper has shown remarkable composure for a player his age," Celtics head coach Joe Mazzulla said in a statement. "He prepares like a veteran, plays with passion every night, and his willingness to accept coaching has accelerated his development beyond what we hoped for."

The rookie's impact extended beyond individual numbers as the Celtics secured the third seed in the Eastern Conference playoff standings. Flagg delivered several clutch performances in high-pressure situations, including a 32-point showing against the Milwaukee Bucks in March and a game-winning basket against the New York Knicks in February.

Flagg becomes the fifth Celtic to win Rookie of the Year honors, joining an illustrious list that includes Larry Bird, Paul Pierce, and Kevin Garnett. His combination of two-way play and leadership qualities has drawn comparisons to some of the franchise's all-time greats, though team officials are cautious about placing too much pressure on the young phenom.

The award comes with significant financial benefits as well, triggering a contract bonus worth approximately $3.5 million. Flagg is expected to sign a long-term extension with Boston this summer, securing his future with a franchise that views him as a foundational piece for sustained championship contention.
