Boston Celtics
A record-breaking 18th title, a historic three-pointer start, and a heartbreaking second-round exit defined a season that ended the run for back-to-back glory.
The 2024–25 season marked the Boston Celtics' 79th year in the National Basketball Association. Entering as defending champions after defeating the Dallas Mavericks in five games to secure their NBA-record 18th title, the team aimed for back-to-back Finals appearances not seen since 1986 and 1987, and consecutive championships unseen since 1968 and 1969. The campaign began with high promise as the Celtics tied an NBA record for three-pointers in their opening game. However, the season concluded abruptly in the second round of the playoffs when a devastating Achilles injury to star Jayson Tatum helped fuel a six-game upset by the New York Knicks. This eliminated the Celtics before the conference finals for the first time since 2021.

Lore & Background
The narrative of the 2024–25 campaign was defined by a clash between historic ambition and sudden tragedy. The Celtics entered with the weight of history on their shoulders, seeking to become the first team since 1968–69 to win consecutive championships. Their opening game set an electric tone, tying the NBA record for most three-pointers made in a single contest. By March 15, they had secured their 11th straight playoff berth with a narrow 115–113 victory over the Brooklyn Nets, appearing poised to continue their dominance. In the first round, they dispatched the Orlando Magic in five games, looking unstoppable. The turning point arrived in the conference semifinals against the New York Knicks. Despite entering as major favorites, the Celtics' season unraveled following a devastating Achilles injury to star player Jayson Tatum. The team fell in six games, marking the seventh straight year without an NBA repeat champion and the sixth consecutive instance where defending champions failed to advance past the second round. This result was particularly stinging as it represented the first time since 2021 that Boston had been eliminated before reaching the conference finals.
In Their Own Story
The season opened with a bang, as the Celtics tied an NBA record for three-pointers in their very first game, signaling offensive potency. By mid-March, the path seemed clear; a 115–113 win over the Brooklyn Nets on March 15 clinched their 11th consecutive playoff appearance since 2015. The first round offered no resistance, with Orlando Magic falling in five games to send Boston to the conference semifinals. The atmosphere shifted irrevocably during the series against the New York Knicks. What began as a championship run turned into a heartbreak when star Jayson Tatum suffered a devastating Achilles injury. The Celtics, who had entered the series as heavy favorites, could not recover from the loss. They were eliminated in six games, ending their bid for back-to-back titles and extending the league's streak of non-repeat champions to seven years. The defeat was historic in its timing; it was the first time since 2021 that the Celtics failed to reach the conference finals.
