The NBA G League, or simply the G League, is the official minor league organization of the National Basketball Association (NBA). The league was known as the National Basketball Development League (NBDL) from 2001 to 2005, and the NBA Development League from 2005 to 2017. The league started with eight teams until NBA commissioner David Stern announced a plan to expand the NBA D-League to 15 teams and develop it into a true minor league farm system, with each NBA D-League team affiliated with one or more NBA teams in March 2005. At the conclusion of the 2013–14 NBA season, 33% of NBA players had spent time in the NBA D-League, up from 23% in 2011. As of the 2024–25 season, the league consists of 31 teams, 30 of which are either single-affiliated or owned by an NBA team, along with the Mexico City Capitanes independent team. Within the G League, players can get a contract from an NBA team and land themselves an official roster spot.
