The JBA was first announced on December 20, 2017, when media personality LaVar Ball said to Slam magazine that he would create a professional league targeted at high school graduates and fully funded by his sports apparel company Big Baller Brand.

[1][2] The league held tryouts in Irvine, California in April 2018, attracting about 25 prospects, and having already handpicked a nearly completed roster of 7 members for the Los Angeles Ballers.

[3] One significant addition to the Ballers was Greg Floyd Jr., a four-star recruit out of Las Vegas who had spent a season at Antelope Valley College due to NCAA eligibility issues.

[4][5] In May, the team added LaMelo Ball, who did not graduate from high school, the youngest son of the league's founder LaVar and a former five-star recruit with limited professional experience, who the JBA labeled as its "marquee player" for the debut season.

On August 16, 2018, after the JBA season, former Los Angeles player Brandon Phillips alleged that the league only paid him one-third of what was promised.
