Win Shares: 4.69

The 2016 postseason signified James' second playoffs since making his return to Cleveland. It just so happens it was a fruitful one for both he and his Cavaliers, as they would go on to win the Finals in epic fashion, coming back from a 3-1 deficit to defeat the Golden State Warriors in seven games.

LeBron was named Finals MVP, but there isn't an award that could say how good he was. In 21 games, a 31-year-old James added 26.3 points, 9.5 rebounds and 7.6 assists per game with a box plus-minus of 13.1. His production was off the charts, but so was his efficiency -- LeBron finished with a PER of 30.0 and .274 win shares per 48 minutes.
