Efficiency Ratings: Game 8

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 Butler Bulldogs made the game tough on Duke. Coach Brad Stevens' team slowed the game down and forced Duke to beat him by settling for perimeter jumpers. For much of the game the Blue Devils were ice cold from the arc, before Kyrie Irving and Nolan Smith began to break down the triangle and two defense and attacked the basket to help Duke to an 82-70 victory. Saturday's game saw Kyle Singler foul out in just 29 minutes of action.

(change from previous game)


*- Hairston and Thornton each saw less than one minute of action with Hairston recording a steal. Efficiency ratings require at least two minutes played.

Notes: Cold outside shooting and the Bulldogs' scrappy defense kept most of the efficiency ratings down for the team on Saturday. Nolan Smith and Andre Dawkins provided the highest scores of the day with 18 points apiece. Kyrie Irving recorded a +17 that would have been higher had it not been for the freshman's season high five turnovers. Smith's score was limited by his field goal percentage (5-of-13 and 1-of-6 from 3pt). Inside Mason Plumlee posted a respectable efficiency score at +14 thanks to his rebounding (8) while Miles Plumlee and Ryan Kelly combined to post a +6 score at the second big position despite the duo shooting a combined 2-of-8 from the field.

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

  • Kyrie Irving +35/+12
  • Nolan Smith +25/+12
  • Mason Plumlee +36/+7

Notes: Irving maintains his sizable lead over the rest of the pack while Mason Plumlee loses a bit of ground to Nolan Smith. Irving's lead over Smith is nearly double Smith's lead over Plumlee for the third spot in the rankings. In a surprising turn of events Andre Dawkins is slowly creeping up the ratings and is making a run towards Singler in the fourth position. Against Butler Dawkins posted his highest output of the season while Ryan Kelly posted his lowest E-rating of the season.
