Efficiency Ratings: Game 35

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.

Duke beat up on a clearly overmatched Hampton team in the second round of the NCAA Tournament's West Regional. The news of the day, however, was the return of freshman phenom Irving who overcame some obvious rust in the first half to post a game high 14 points. While never being challenged, Duke was able to employ hockey style line changes throughout the second half - subbing five players at a time. The increased playing time allowed several players to factor into the box score and thus the efficiency ratings.

(change from previous game)

Notes: Irving's return was better than expected from an efficiency standpoint. The freshman scored 14 points, grabbed four rebounds, handed out an assist, recorded two steals and a block. All while shooting 50 percent from the field to post a +16. In limited minutes both Singler and Smith posted reduced numbers. Singler had just a +6 rating thanks to three turnovers and reduced rebounding numbers from the ACC Tournament. Meanwhile Smith scored just nine points and grabbed just a pair of rebounds, but did manage a 7-to-1 assist to turnover ratio which resulted in a +14 rating. The most efficient Blue Devil on the afternoon, however, was Miles Plumlee who used 13 rebounds and eight points to log a +21 rating. As a whole the three post players (the Plumlees and Ryan Kelly) posted a combined +45 rating.

Throughout the season TDD will track the various highs and lows using the formula.

Tracking the most and least efficient performances by player

  • Kyrie Irving +35/+12
  • Nolan Smith +36/-6
  • Mason Plumlee +36/+0
  • Kyle Singler +34/-1
  • Andre Dawkins +23/-4
  • Seth Curry +27/-3

  • Tyler Thornton +12/-4
  • Josh Hairston +15/-1

Notes: Miles Plumlee posts a season high +21 rating to lead the Blue Devils while Kyrie Irving's +16 rating in his return actually lowered his per game average to a team high 20.1. Seth Curry continues to sneak up on Ryan Kelly for fourth place in the seas standings, while the elder Plumlee began to distance himself from Andre Dawkins for the team's sixth highest efficiency score this season.
