YEAR: 1966
SIGNIFICANCE: The NBA officially granted Seattle, Washington an expansion franchise (Supersonics)
In the final season of the Bill Russell-guided Celtics’ reign of terror — during which they won eight straight championships — an expansion franchise was born. On this day in 1966, the NBA awarded the city of Seattle, Washington the SuperSonics, serving as Seattle’s first major league sports franchise. The squad from the Pacific Northwest limped to the finish line in their inaugural season (23-59 record), captained by All-Stars Walt Hazzard and Tom Meschery. The new west coast team saw steady improvement over the next five years, finally putting together a season above .500 at 47-35 in 1971-72.
In 1975, the aforementioned Bill Russell became the head coach and took them to the playoffs for the first time. Seattle’s first Finals run came when Lenny Wilkens took the reigns as coach, turning them into title contenders. In the 1979 season, their dream came into fruition as they dismantled the Bullets 4-1 in the Finals, granting the franchise its only championship. Despite Washington state’s frenetic fanbase, the SuperSonics were relocated to Oklahoma City, OK in 2008 to be rebranded as the Thunder. The franchise, still residing in OKC, has drafted three MVPs and made a Finals appearance since relocating.
