In 2005, the league entered its second major phase — the NBA Development League (D-League). The rebrand reflected the NBA’s commitment to deepening its developmental infrastructure, transforming the NBDL into a more organized, nationally recognized system.
Expansion followed quickly. The D-League grew to 15 teams, spreading beyond the Southeast into Texas, California, and the Midwest. For the first time, each NBA franchise could affiliate with one or more D-League teams, allowing players to move fluidly between leagues.
In 2009, the introduction of the hybrid model revolutionized operations. Under this system, NBA teams managed basketball operations while independent owners handled business affairs. The Houston Rockets–Rio Grande Valley Vipers partnership became the blueprint for success — demonstrating how NBA organizations could directly influence player development and playing style.
By 2015, nearly every NBA team had either ownership of or an affiliation with a D-League franchise. The league was no longer just a developmental experiment; it had become an essential pipeline, shaping players, coaches, referees, and executives for the modern NBA.
