The Brooklyn Nets Trade For Kevin Garnett, Paul Pierce, and Jason Terry (2014)

If you created a top ten (or top five) list of the worst trades in the history of sports, the trade between the Boston Celtics and Brooklyn Nets, which sent Kevin Garnett, Paul Pierce, Jason Terry, and D.J. White to Brooklyn in exchange for five players plus Brooklyn’s first-round picks in 2014, 2016 and 2018, and the rights to swap first-round picks in 2017, would garner serious consideration for inclusion on said list.

Former Nets’ owner Mikhail Prokhorov’s gambit to turn the Nets into an instant contender failed after just a handful of seasons, and crippled any chance of the Nets rebuilding their team in the aftermath of this deal.
