Efficiency Ratings: Game 16

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 Blue Devils have looked vulnerable for a while. On Wednesday night they looked even worse and ended up being out-hustled, out-worked, out-rebounded, and just simply beaten by Florida State. Aside from the younger Plumlee's work inside on the glass, Duke had nothing in the paint on either side of the ball which allowed an offensively challenged Florida State team to continually punish the Blue Devils with second change points while forcing Duke to be a nearly exclusive perimeter shooting team.

v. UAB
(change from previous game)

Notes: Smith and Singler both produced well enough, but their scores would have been a bit higher were it not for the woeful shooting performance (combined 12-of-33) from the field. Additionally, Smith recorded just one rebound for the game. Despite not scoring (or shooting much), Mason Plumlee posted his second best efficiency score in the last three weeks thanks to 14 rebounds. Meanwhile, the other big position (a combination of Ryan Kelly, Josh Hairston, and Miles Plumlee) was quite unproductive and inefficient. That trio combined to score just a +5 efficiency rating between them with the elder Plumlee recording a -1 in just six minutes of action.

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

Ten Most Efficient Performances

  • Mason Plumlee v. Marquette (+36)
  • Nolan Smith v. UNC-Greensboro (+36)
  • Kyrie Irving v. Michigan State (+35)
  • Nolan Smith v. Miami (+31)
  • Nolan Smith v. UAB (+31)
  • Kyle Singler v. UNC-Greensboro (+29)
  • Kyle Singler v. Oregon (+27)
  • Kyrie Irving v. Princeton (+26)
  • Nolan Smith v. Princeton (+25)
  • Nolan Smith v. Elon (+25)

Five Least Efficient Performances*

  • Seth Curry v. Miami (-3)
  • Seth Curry v. Michigan State (-2)
  • Tyler Thornton v. Kansas State (-2)
  • Tyler Thornton v. Bradley (-1)
  • Miles Plumlee v. Florida State (-1)
*- players must play at least 2 minutes or factor into the box score in some what to be considered for per game E-ratings

Cumulative Season ratings for the Blue Devils. (E/game)*

  • Nolan Smith +324 (20.3)
  • Kyle Singler +271 (16.9)
  • Mason Plumlee +209 (13.1)
  • Andre Dawkins +189 (11.8)
  • Kyrie Irving +165 (20.6)
  • Ryan Kelly +143 (8.9)
  • Miles Plumlee +125 (7.8)
  • Seth Curry +112 (7.0)
  • Tyler Thornton +35 (2.9)
  • Josh Hairston +31 (2.8)
*- players must play at least 2 minutes or factor into the box score in some what to be considered for per game E-ratings. Irving (E/8); Thornton (E/12); Hairston (E/11)

Tracking the most and least efficient performances by player

  • Kyrie Irving +35/+12
  • Nolan Smith +36/+4
  • Mason Plumlee +36/+0
  • Kyle Singler +29/+7
  • Andre Dawkins +23/+1
  • Seth Curry +18/-3
  • Ryan Kelly +17/+2
  • Miles Plumlee +19/-1
  • Tyler Thornton +7/-2
  • Josh Hairston +15/+0

Notes: Duke's offense continues to struggle as the team searches for an identity on offense against good teams. Clearly the performance of the stable of bigs has suffered with Miles Plumlee posting a season low rating against Florida State. With Kyrie Irving now having missed as many games as he's played, he still ranks fifth on the team in total E-rating points and 1st in E/game. While that's a testament to his abilities on the court it is also a telling fact. Duke's offense has gone from a three headed monster with several secondary weapons - each capable of scoring large amounts of points on any given night - to a two pronged attack with sporadic help from the secondary options.
