BOSTON, MA — July 6, 2025 — The moment Celtics fans—and frankly, the entire basketball world—have been waiting for is finally here: Cooper Flagg is officially a Boston Celtic.
The No. 1 overall pick in the 2025 NBA Draft put pen to paper on his rookie contract today at the Auerbach Center in Boston, making his long-anticipated NBA debut one giant step closer to reality. Flagg, 18, joins the storied franchise as the most hyped prospect since LeBron James, with expectations sky-high for the Maine native who dominated high school and college basketball with a rare mix of athleticism, court vision, and two-way prowess.
“It’s a dream come true,” Flagg said at the press conference following the signing. “To be drafted by a team with this kind of legacy—and now to officially be part of it—is surreal. I can’t wait to get started and earn my place in Celtics history.”
The rookie contract, reportedly a four-year deal worth $57.6 million, includes team options in the final two years, standard for a No. 1 overall pick under the NBA’s rookie wage scale. While financial terms haven’t been officially disclosed, insiders suggest performance-based incentives and marketing clauses were also part of the package, signaling the Celtics’ long-term commitment to their future franchise player.
Flagg, who stands 6-foot-9 with a 7-foot wingspan, was widely regarded as the most NBA-ready player in this year’s draft. His standout freshman season at Duke University was nothing short of historic—averaging 20.1 points, 9.8 rebounds, 3.2 assists, and 2.7 blocks per game—while leading the Blue Devils to the Final Four. His versatility, defensive instincts, and leadership earned him comparisons to legends like Kevin Garnett and Scottie Pippen.
Boston, fresh off a deep playoff run that ended in the Eastern Conference Finals, sees Flagg as the missing piece to push them back into championship contention. President of Basketball Operations Brad Stevens was all smiles during the signing ceremony.
“Cooper brings everything you want in a young player—talent, maturity, and an unbelievable work ethic,” Stevens said. “We’re thrilled to have him on board. The fans are going to love what he brings to the floor.”
Indeed, Flagg’s arrival has sparked a surge in ticket sales, social media buzz, and renewed hope for Banner 18. Jersey preorders bearing Flagg’s No. 32 sold out within hours of the announcement, and the rookie is expected to make his first public appearance in green and white at the upcoming NBA Summer League in Las Vegas.
As the Celtics gear up for a new season, one thing is clear: Cooper Flagg isn’t just a top draft pick—he’s the future face of a franchise hungry for another championship. And now, with the ink dry on his contract, that future officially begins.
