Efficiency Ratings: Game 13

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

As the Blue Devils progress through the season there will be many different theories on how to measure team success. TDD has adopted the NBA Efficiency Formula to track Duke's top players and performances after each game and throughout 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.


LATEST GAME
The ACC opener saw the Blue Devils ride a great performance from Smith to a 13th victory on the season while holding Miami's guards in check for most of the night. Much of the game plan focused on Duke's defensive ability as Miami was held to just 3-of-17 shooting from the perimeter. The lack of a perimeter attack hurt the Hurricanes badly despite Miami winning the battle of the turnovers. The Blue Devil offense was largely build off of defense as Duke scored just 74 points which included just two fast break points.

(change from previous game)


Notes: Nolan Smith logged his second consecutive game of 30 or more Efficiency Points with the (tied for) third most efficient performance of the season at +31 points. Smith put up a game high in points while shooting 9-of-15 from the field. He also rebounded and dished without committing many turnovers (2.5/1 assist to turnover ratio). Duke also got an improved performance from Andre Dawkins and Ryan Kelly with +17 and +16 E-ratings respectively. Mason Plumlee's rough shooting night (1-of-5) and turnover problems (4) overcame his impressive night on the boards (10).

SEASON HIGH/LOW PERFORMANCES
Tracking the most and least efficient performances by player

  • Kyrie Irving +35/+12
  • Nolan Smith +36/+4
