Derrick White has agreed to a four-year, $125.9 million contract extension with the Boston Celtics, featuring a player option. This extension follows his pivotal role in the Celtics' recent championship run, where he averaged 15.2 points, 4.2 rebounds, and 5.2 assists. White's performance has solidified his reputation as one of the NBA's premier two-way guards, earning All-Defensive team honors in the last two seasons. Alongside White, Jayson Tatum also secured a record-breaking five-year, $315 million extension. These moves are part of the Celtics' strategy to maintain their championship-winning core, despite the luxury tax implications. The franchise is now positioned for a potential dynasty with their key players locked in long-term deals.
