5 worst losses in LeBron James' career

#3 - San Antonio Spurs 113-77 Miami Heat; 11 June 2013

With the Finals tied at 1-1, the Spurs clobbered the Heat in Game 3, to seemingly take control of the series. After a back-and-forth encounter up to halftime, the Spurs seized control.

San Antonio went on a 50-25 run, led by some crazy long-range shooting by Danny Green and Gary Neal, as the Spurs set the then-record for most threes in a Finals game with 16.

The Heat, on the other hand, struggled, especially LeBron James. He missed 11 of his first 13 shots, bothered by Kawhi Leonard's defense. The big three combined for just 43 points, as the Spurs went full lockdown mode.

The rest of the team didn't fare any better except Mike Miller who hit all five of his three-pointers. It remains the third-largest margin of victory in an NBA Finals game.
