The deal, which includes a player option, was announced just one week after the team's triumphant victory in the NBA Finals, securing their league-leading 18th championship.

Tatum's massive contract now stands as the richest in NBA history, surpassing the previous record set by his teammate Jaylen Brown. His eligibility for the supermax extension was due to his inclusion in the All-NBA team for the 2023-24 season, solidifying his status as one of the game's top talents.

The Celtics' decision to lock up Tatum comes as no surprise after his outstanding contributions to the team's success. Drafted in 2017 as the third overall pick, joining forces with Brown who was drafted the year before, Tatum has emerged as an integral part of Boston's future dynasty. This extension solidifies the foundation on which the Celtics hope to build their success in the coming years.

Tatum's statistics from the previous season demonstrate his value as a player. He averaged an impressive 26.9 points, 8.1 rebounds, and 4.8 assists while shooting 47 percent from the field. During the playoffs, his performance remained stellar, with averages of 25.0 points, 9.7 rebounds, and 6.3 assists per game.

With Tatum's extension, the Celtics have demonstrated their commitment to keeping their core lineup intact. Alongside Jaylen Brown, who signed a record-setting $300 million supermax extension last year, the team is ready to compete at the highest level for the foreseeable future. Additionally, securing Derrick White on a new deal further solidifies Boston's roster moving forward.

The Celtics organization has high hopes for Tatum and Brown, who have shown incredible potential and growth throughout their tenure. Their combined talent and on-court chemistry make them an unstoppable force, and the team's management believes they hold the key to future success.

As the 26-year-old Tatum enters the next phase of his career, there is no doubt that the Boston Celtics have made a bold investment, recognizing his immense talent and potential. With their star duo in place, the team is poised to compete for championships for years to come. Celtics fans can rejoice knowing that their beloved franchise has secured the services of one of the brightest stars in the game.
