The upcoming game between the Boston Celtics and the Dallas Mavericks on Tuesday will mark the initial NBA matchup between rookie forward Cooper Flagg and Celtics star Jayson Tatum. Flagg, who played college basketball at Duke University—the same program that produced Tatum—expressed appreciation for the guidance he has received from the Celtics’ standout during his transition into professional basketball. This game holds added significance as it highlights the connection between two players who share a similar developmental background.
Flagg Credits Tatum for Valuable Mentorship Early in His Career
Cooper Flagg openly acknowledged Tatum’s support during the early stages of his career, revealing that the veteran player reached out to offer advice and encouragement. Flagg emphasized the shared experiences they have had, given their comparable paths to the NBA.
He’s somebody that’s reached out to me and been there to give me advice, Flagg said on Tuesday.
“He kind of followed a similar path to me, so you know he’s been there.”
Draft Paths and Team Context Set Distinct Expectations for Both Players
Flagg was selected as the first overall pick in the 2025 NBA Draft by Dallas, whereas Tatum was picked third overall in 2017 by Boston. While Tatum entered a Celtics team with high championship aspirations, Flagg joined the Mavericks amid a period of transition following the trade of Luka Dončić, the franchise’s former leading player. Dallas fans are now looking to Flagg to fill the void left by Dončić and lead the team forward.
Future Prospects for a Highly Anticipated Matchup
Though Tatum remains sidelined due to a torn Achilles injury, his expected return, likely next season, signals a promising and eagerly awaited showdown with Flagg. This potential matchup between two talented players who originated from Duke and are now emerging as key figures in their NBA teams will draw significant attention from fans and analysts alike.
