This left upstate New York without a team until the Buffalo Braves were established in 1970. This third attempt did not last, with the Braves moving to San Diego, California in 1978 to become the San Diego Clippers. In 1970, the Cleveland Cavaliers were established. This brought a new rival for the Royals, as well as a new team in Ohio. This rivalry did not last, and the Royals moved to Kansas City only a few years later. Although the NBA previously had a team in St. Louis, Missouri in the form of the St. Louis Hawks, that team moved to Atlanta in 1968, thus preventing a potential new rivalry for the Kings. This made the Kings the first team in the state in four years. 13 years later, the Kings moved to California, leaving Missouri without a team.
