Just a year after a young head coach won the NBA Finals, the 2025 championship matchup could feature a similar scenario.
Last season, Joe Mazzulla became the youngest head coach since 1970 to win the NBA championship when the Boston Celtics topped the Dallas Mavericks in five games. Mazzulla was 35 years and 353 days old at the time.
In the 2025 NBA Finals, Oklahoma City Thunder head coach Mark Daigneault would still be one of the youngest head coaches to win a championship.
Daigneault is in his first NBA head-coaching role after taking over in 2020. He was the head coach of Oklahoma City’s developmental team, the Blue, from 2014 to 2019 following some years as an assistant coach at the college level.
Now in the fifth year of his job, Daigneault can help Oklahoma City make history with a series win when it faces the Indiana Pacers, led by head coach Rick Carlisle, who has two NBA rings to his name (in 1986 as a player and in 2011 as the Mavs’ head coach).
