Gregg Popovich, a monumental figure in the NBA, officially stepped down as head coach of the San Antonio Spurs after a 29-year tenure, a period that saw the team secure five championships. Announcing his transition to President of Basketball Operations, Popovich expressed gratitude to players and fans, highlighting the significance of his time as head coach.

In his absence, Victor Wembanyama, the Spurs' rising star, will now play under newly appointed head coach Mitch Johnson. Wembanyama reflected on his two years learning from Popovich, sharing an emotional message of thanks. Throughout Popovich’s final season, while the Spurs missed the playoffs, they made noteworthy additions, including point guard De'Aaron Fox, invigorating hopes for the franchise's future.

The Memphis Grizzlies have made a significant move by appointing Tuomas Iisalo as their new head coach, following the dismissal of Taylor Jenkins. Iisalo, who previously served as the interim coach, becomes the first Finnish-born head coach in NBA history. After taking over Jenkins in late March, he finished the season with a respectable 4-5 record. His experience includes being named EuroCup Coach of the Year in April 2024 while coaching Paris Basketball. At just 42, Iisalo is poised to create a lasting impact in Memphis as he embarks on his first full season as an NBA head coach. However, the announcement has met mixed reactions from fans, with some expressing skepticism about the decision and concern over star player Ja Morant's future with the franchise.
