The 1977–78 Boston Celtics season was the 32nd season of the Boston Celtics in the National Basketball Association (NBA) and was linked to the Buffalo Braves season. While the Braves were struggling on the court, their owner John Y. Brown brokered a deal to take over the legendary Celtics franchise. Celtics owner Irv Levin wanted to move the franchise to California; however, the NBA would not allow him to take the cornerstone franchise out of Boston.
