The San Antonio Spurs are an American professional basketball team based in San Antonio, Texas.  They are a member of the Southwest Division of the Western Conference in the National Basketball Association (NBA).  The franchise was founded as the Dallas Chaparrals of the American Basketball Association (ABA) in 1967.  The team suffered from poor attendance and general disinterest by fans in Dallas, and the name "Dallas" was dropped in favor of "Texas" during the 1970–71 season in an attempt to make the team regional.  This also proved to be a failure, and the team returned full-time to use "Dallas" for the 1971–72 season.  The team was put up for sale after missing the playoffs in the 1972–73 season.  The team was acquired by a group of 36 San Antonio businessmen, led by Angelo Drossos and Red McCombs, who relocated the team to San Antonio, Texas and renamed it to Spurs.  In 1976, the ABA folded, threatening the future of San Antonio's sole professional sports franchise.  The NBA, however, decided to admit four ABA teams into the league, including the Spurs, along with the Denver Nuggets, the Indiana Pacers and the New York Nets.
