Efficiency Ratings: China Game 1

Using the NBA Efficiency Rating Formula, TDD tracks the best statistical performances of the season

A quick way NBA coaches measure a player's game performance is by evaluating his efficiency. In order to find a player's efficiency the following formula is used:

((Points + Rebounds + Assists + Steals + Blocks) - ((Field Goals Att. - Field Goals Made) + (Free Throws Att. - Free Throws Made) + Turnovers)).

For example, compare the following stat lines:

Player A: 17 points (5-of-22 FG, 7-9 FT), 8 rebounds, 6 assists, 3 steals, 4 turnovers.

Player B: 15 points (5-8 FG, 3-4 FT), 4 rebounds, 7 assists, 2 turnovers

Who had the better game? Using the NBA formula player B, who hit five of eight shots and committed two turnovers registered a +20 efficiency total while Player A who missed 17 shots and had four turnovers had just a +11 rating.

For reference, last year LeBron James posted the two most efficient games of the season with a +54 (37 points on 11-of-17 FG & 9-10 FT, 12 rebounds, 11 assist, 2 steals, 1 block, and 2 turnovers) and +50 (40 points on 16-of-23 FG & 6-6 FT, 8 rebounds, 8 assist, 1 steal, 2 blocks, and 2 turnovers) rating.

The 2011-2012 season kicks off with the Blue Devils on a four game international tour through China. Monday marked the team's first game of the new season.

Kelly shot 6-of-9 from the field while also adding a pair of blocks and steals. On the wing Duke got a boost from Andre Dawkins and Austin Rivers who combined for a +38 rating. Rivers made his unofficial Duke debut by leading the team in scoring (18 points) while shooting 8-of-15 from the field. He also logged a game high five assists. Dawkins added 17 points, six rebounds, and three steals to finish with a +22 rating. Inside Duke saw the three Plumlee brothers combine for a +20 score led by starter Miles Plumlee's +10 rating.
