In 2013 the Nets completed the worst trade ever with the Celtics. The trade included Paul Pierce, Kevin Garnett, Jason Terry to the Nets for Gerald Wallace, Kris Humphries, MarShon Brooks, Keith Bogans, Kris Joseph and three unprotected first-round draft picks. The draft picks turned into Jaylen Brown, Jayson Tatum and the third was part of the trade to get Kyrie Irving form the Cavaliers. While the Nets made the playoffs short term, the trade destroyed any hope of drafting any good young players.  The Celtics turned into title contenders while the Nets became part of the bottom of the NBA with no draft picks to build for the future.  While at the time the trade may have made some sense to the Nets who wanted a title push, even at the time the trade was being questioned. The Celtics went through a small rebuild period, but with three top picks they are not one of the better teams. The Nets got worse and worse and couldn’t draft and players in the lottery as they didn’t have any picks.
