Miami Receive: LeBron James

Cleveland Recieve: Two first-round picks, Two second-round picks, A trade exception

While technically a free-agent signing, LeBron James' sign-and-trade deal ensured the Cavaliers received some compensation for his departure - though it did little to soften the blow.

In his ESPN special, The Decision, LeBron declared: “I'm taking my talents to South Beach.”

The announcement sent shockwaves through the NBA and sparked outrage in Cleveland, where fans burned jerseys in protest.

Cavaliers owner Dan Gilbert added to the drama, publishing a scathing letter condemning LeBron's exit as “a cowardly betrayal.”
