Efficiency Ratings: Game 10

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.

The second game without Irving provided Duke a second chance to adjust to the different pace - one that marries last season's approach with this year's faster pace attack. After a slow start Duke started hitting shots off the dribble, making the extra pass, and showed the ability to go on quick runs of double figure differences to blow out St. Louis.

Notes: In his second game running the point, senior Nolan Smith appeared to be far more comfortable in meshing his on the ball and off the ball responsibilities. Smith led the team in scoring (22), but also made his presence felt on the glass (6) and in handing out assists (5), though he was still saddled with turnovers (4). Classmate Kyle Singler continued to play well, scoring 21 points and registering a +18 mark. While sophomore big man Mason Plumlee registered his lowest rating of the season with just a +2, older brother Miles continued his recent string of strong play by posting a +16.

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 +25/+4
  • Mason Plumlee +36/+2
  • Kyle Singler +27/+7
  • Andre Dawkins +23/+1
  • Seth Curry +18/-2
  • Ryan Kelly +15/+2
  • Miles Plumlee +19/+1
  • Tyler Thornton +7/-2
  • Josh Hairston +15/+0

Notes: With another solid performance, Miles Plumlee has moved ahead of both Seth Curry and Ryan Kelly for sixth place in the season E-ratings. Meanwhile, Smith has taken over the top overall position on the season ratings, edging in front of sidelined freshman Kyrie Irving by four points. However, Irving remains - by far - the team's highest per game E-rating player at more than 20 points per contest. Freshman Josh Hairston's career best day is also worth mentioning as he posted a high water mark of +15 which is equal to secondary big man spot starter Ryan Kelly's top effort.
