The 1958–59 Cincinnati Royals season is arguably the most difficult ever faced by an NBA team in the league's history.
 The reason was the tragic career-ending head injury to star Maurice Stokes, who became permanently hospitalized at the age of 24 at the end of the previous season, which had been the team's first in Cincinnati.
 The loss of Stokes shocked six other roster players into retirement.
 Also, the team had been sold to new, inexperienced local ownership and also soon had to replace their coach.
 No NBA team was ever so suddenly decimated.
The NBA G League is the National Basketball Association's official minor league basketball organization.
 The league was known as the National Basketball Development League (NBDL) from 2001 to 2005, and the NBA Development League (NBA D-League) from 2005 until 2017.
 The league started with eight teams until NBA commissioner David Stern announced a plan to expand the NBA D-League to fifteen 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 2017–18 season, the league consists of 26 teams, all of which are either single-affiliated or owned by an NBA team.
The 1961 NBA Expansion Draft was the inaugural expansion draft of the National Basketball Association (NBA).
 The draft was held on April 26, 1961, so that the newly founded Chicago Packers could acquire players for the upcoming 1961–62 season.
 The Packers were the second NBA team from Chicago, after the Chicago Stags, which folded in 1950.
 The Packers later underwent several name changes and relocations before moving to Washington, D.C..
 They are currently known as the Washington Wizards.
 In an NBA expansion draft, new NBA teams are allowed to acquire players from the previously established teams in the league.
 Not all players on a given team are available during an expansion draft, since each team can protect a certain number of players from being selected.
