Billy King's Transactions

August 2015:  Nets waive Deron Williams and his remaining two years of contract. Will cost Nets $27.5 Million over next 5 years.  
To be clear, this is the guy that Billy King traded multiple draft picks and Derrick Favors for.  Then, King traded several more draft picks and spent a lot more money to make him happy.  Absolute failure.

June 2015:  
Traded Mason Plumlee and 41st pick in the draft for Portland's 23rd pick in the draft, 
Rondae Hollis-Jefferson.  
Mason Plumlee, a 1st All-Rookie team player, had just made Team USA's international team and had his career's high in points, rebounds and FG%.  It was great having him as a Net.  King, with his usual itch has to trade him as soon as possible.

June 2015:
Trades a 2018 2nd round pick and their own 2019 2nd round pick for Charlotte's 2nd round pick (#39) to draft Juan Pablo Vaulet.  
Yep, Billy King just traded two future picks for a second round foreigner that won't be playing in the NBA.  

February 2015:
Traded Kevin Garnett for Thaddeus Young.  So to recap, the Nets traded 3 unprotected first round picks to Boston (2014, 2016, 2018) and a pick swap in 2017 and 1.5 years later have Thaddeus Young to show for it.  NBA All-Star starters have been traded for less.  Further, Young is on the last year of his deal.  This sets Billy King up for another overpay multiyear locked in contract that fans will be regretting in about a year.

December 2014:  Andrei Kirilenko, Jorge Gutierrez, and a 2020 2nd round draft pick traded for Brandon Davies.
One month later Mizra Teletovic has a season ending injury leaving the Nets with no real PF beyond Kevin Garnett who is basically limited to 20 minutes per night if playing.

June, 2014
Jason Kidd traded to Milwakee for two second round picks
Historically this is a terrible haul for a traded coach. The clippers gave Boston a first round pick when signing Doc Rivers. Miami gave the Knicks a first round pick when signing Pat Riley. Even Miami gave Orlando the right to swap 1st round picks and an additional second round pick when signing Stan Van Gundy and he wasn't even their coach, having resigned several years before to let Pat Riley be coach. 

February 2014 Traded Jason Terry and Reggie Evans for Marcus Thornton.
Thornton ranked 11th worst contract in the NBA in Bill Simmons 2014 column. Thornton had a minor role for the Nets in the second half of last season before being traded again as the team wanted to go in another direction.   

July 2013, Gerald Wallace, Kris Humphries, Marshon Brooks, Kris Joseph and 3 unprotected first-round draft, plus abilities to swap another draft pick for Paul Pierce, Kevin Garnett, Jason Terry, and DJ White.
Could be the worst trade in franchise history. The Nets actually won less games with this new roster, Pierce left after one season, and Garnett's future is unknown, after having career lows in all statistics. Management has even acknowledged this move was a serious mistake.  

July 2012, Traded Jordan Farmer, Johan Petro, Anthony Morrow, Deshawn Stevenson Jordan Williams, a first round draft pick and the rights to swap a future first round draft pick for Joe Johnson
While Joe Johnson brought another talented player to Brooklyn his contract was considered terrible. No team in the NBA was willing to trade for him due to his overpriced contract. Ranked #4 worst NBA contract in 2014 by Bill Simmons. Yet, not only did King trade for him, but gave away a draft pick and the right to swap an addition first round draft pick for him. No other team had any interest in Johnson's toxic contract, and nonetheless would give away picks for it.

July 2012, signed Gerald Wallace to $40 Million contact.
Considered one of the worst contacts in the NBA. Ranked #2 worst contact of 2014 by Bill Simmons. Contract was terrible from the start. Nets had to give away two additional first round picks plus right to swap a pick just to trade him away a year later to Boston. 

July 2012, signed Brook Lopez to Max contract
Ranked 21st worst contract of 2014 by Bill Simmons. 

July 2012, signed Deron Williams to Max Contract
Ranked #5 worst contract of 2014 by Bill Simmons. 

March 14, 2012 Traded Shawne Williams, Mehmet Okur and a two first round pick to Portland for Gerald Wallace.
Bringing in a overpriced Gerald Wallace so the Nets could have a better losing record made zero sense now and zero sense then. This transaction led to a terrible contract resigning even though the Nets could have signed Wallace to the same contract in the off-season with no trade needed. Further, the Nets traded two first round picks, one being the 6th pick in the draft, All-Star Damian Lillard. When asked why King didn't put further protections on the draft pick, he felt there wasn't any talent after top 3 spot.

February 23rd, 2011 Traded Derrick Favors, Devin Harris Troy Murphy and two Future 1st round pick for Deron Williams and Brandan Wright.
Not a terrible trade at the time, but controversial at best. King traded most of the building blocks for the Nets future for one player. Sadly, that player was very overrated and is a mediocre PG at best. In hindsight trade was pretty awful.  

August 2010 Traded Courtney Lee for Troy Murphy.
Courtney Lee was a starting SG who could defend.  Troy Murphy was a towel waver at best and was traded a few months later for peanuts.
