They have been based at Barclays Center in Brooklyn since 2012, though have played in the New York metropolitan area their entire existence. The 2014–15 Brooklyn Nets season was the franchise's 48th season, its 39th season in the National Basketball Association (NBA), and its 3rd season playing in the New York City borough of Brooklyn.  This would be the most recent playoff berth for the Brooklyn Nets as of the 2016-17 season The 2011–12 New Jersey Nets season was the 45th season of the franchise, their 36th in the National Basketball Association (NBA), and their 35th and final season in New Jersey before moving to Brooklyn, New York and changing their name to the Brooklyn Nets for the 2012–13 NBA season.  The Nets finished 22-44, last in the Atlantic Division and 12th overall in the Eastern Conference and failed to make the playoffs for a fifth consecutive season.  Point guard Deron Williams led the team in scoring (21.0), assists (8.7), and minutes per game (36.3) and was the team's lone selection in the 2012 NBA All-Star Game.  Forward Kris Humphries led the team with 11.0 rebounds and 1.19 blocks per game and games played (62). The 2016–17 Brooklyn Nets season was the 41st season of the franchise in the National Basketball Association (NBA), 50th season overall, and its 5th season playing in the New York City borough of Brooklyn.  In the month of February, the Nets would go 0-10 marking the first time that they lost every game in a single month since going 0-14 in November 2009.  This would be Brook Lopez's final year in Brooklyn and the first season with new management.  The Nets hired Kenny Atkinson after Lionel Hollins was fired back in January 2016 when Tony Brown took over as the interim.  Billy King was also fired as the infamous trade back in 2013 where they traded their first round picks in 2014, 2016, and 2018 in exchange for Kevin Garnett and Paul Pierce hurt the Nets badly.  Sean Marks took over as the Nets began rebuilding.  They would finish 20–62, their worst record since 2009–10.
