2015 - The Nets agreed to swap first rounders as part of the 2012
Joe Johnson trade. So they have the 29th pick and the
Hawks the 15th.
2016 - The Nets traded their first rounder, unprotected, to Boston as part of the
Paul Pierce -
Kevin Garnett deal. Those discussions started small with the Nets agreeing to take Pierce for
Kris Humphries and the 2016 pick. Talks then expanded to include KG,
Jason Terry and pieces, including the 2014 and 2018 picks. The Nets agreed to swap second rounders in the 2012
Reggie Evans trade.
Clippers have option to swap picks if Clippers pick is between. So unless the Clippers finish with one of the top five records next season, the Nets and Clippers will swap picks.
2017 - The Nets agreed to swap first rounders with the
Celtics as part of the Pierce - Garnett deal. No protections. Unless the Nets do well in the 2016 free agency --and the Boston rebuild is disappointing-- this pick will likely be swapped. The Nets had to give up their second round pick to the Hawks, the last payment in the Johnson deal. This was a late add to the deal, required by the NBA to satisfy some CBA requirement.
2018 - The Nets traded their first round pick, unprotected, to the Celtics as part of the Pierce - KG deal, the last payment of that deal. It's been suggested one first rounder was for Pierce, one was Garnett and one was payment for taking on Gerald Wallace's $30 million deal.
