The NBA All-Defensive Team is an annual National Basketball Association (NBA) honor given since the 1968–69 NBA season to the best defensive players during the regular season. The All-Defensive Team is generally composed of two five-man lineups, a first and a second team, comprising a total of 10 roster spots. Voting is conducted by a panel of 123 writers and broadcasters. Prior to the 2013–14 NBA season, voting was performed by the NBA head coaches, who were restricted from voting for players on their own team. The players each receive two points for each first team vote and one point for each second team vote. The top five players with the highest point total make the first team, with the next five making the second team. In the case of a tie at the fifth position of either team, the roster is expanded. If the first team consists of six players due to a tie, the second team will still consist of five players with the potential for more expansion in the event of additional ties. Ties have occurred several times, most recently in 2013 when Tyson Chandler and Joakim Noah tied in votes received.
