An NBA player is a professional basketball player who plays in the National Basketball Association. The NBA is the top-tier men's professional basketball league in North America, and it is generally considered the top men's basketball league worldwide. There are five key positions in the NBA: point guard, shooting guard, small forward, power forward and center.
NBA players have a code of conduct they are required to follow to avoid fines or other harsher penalties. The commissioner of the NBA is the chief executive of the National Basketball Association and is responsible for enforcing this code. He is elected to office by the NBA owners. One of the most notable codes enacted by an NBA commissioner is the NBA dress code. On Oct. 17, 2005, presiding NBA commissioner David Stern announced the implementation of a mandatory dress code for all NBA and NBA development players, thereby making the NBA the first major professional sports league to implement such a rule.
The traditional way to advance to the NBA is selection in the NBA draft. The NBA draft is an annual event that, as of 2014, allows the 30 teams from the NBA to draft eligible players who want to join the league. However, there have been a few notable players who went on to have successful careers without being drafted, including Ben Wallace, Avery Johnson and Bruce Bowen.
