Efficiency Ratings: Game 22

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.

After rolling over and never getting out of the gate against St. John's, the Blue Devils set the tone early against Maryland - attacking the basket early and often while taking the fight to the Terrapins. Duke also went inside where the younger Plumlee posted his strongest performance since the UAB game in early January. As noted in the game preview, Duke needed help from secondary sources. On Wednesday they got it from both Curry and Dawkins which helped overcome a performance marred by foul trouble from Kelly.

(change from previous game)

Notes: In the first start of his career, Tyler Thornton played well enough to post a +4 rating. It would have been higher but for a quartet of turnovers caused by Maryland's full court press. After getting very little support from the rest of the team against St. John's, the Blue Devils saw five players reach double figure efficiency ratings against Maryland including a combined +41 from Mason Plumlee, Andre Dawkins, and Seth Curry. Plumlee in particular posted his most efficient performance in a month with 12 points and 11 rebounds. Free throws continue to be a thorn in his side, but aside from that the Duke big man had a huge night in College Park.

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)
  • Ryan Kelly v. Wake Forest (+31)
  • Nolan Smith v. Virginia (+30)
  • Nolan Smith v. St. John's (+30)
  • Nolan Smith v. Boston College (+29)
  • Kyle Singler v. UNC-Greensboro (+29)
  • Kyle Singler v. Oregon (+27)

Five Least Efficient Performances*

  • Seth Curry v. Miami (-3)
  • Seth Curry v. Michigan State (-2)
  • Tyler Thornton v. Kansas State (-2)
  • Tyler Thornton v. Virginia (-2)
  • Ryan Kelly v. Maryland (-1)
*- players must play at least 3 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 +460 (21.9)
  • Kyle Singler +373 (17.8)
  • Mason Plumlee +295 (14.0)
  • Ryan Kelly +230 (11.0)
  • Andre Dawkins +220 (10.5)
  • Seth Curry +171 (8.1)
  • Miles Plumlee +167 (8.0)
  • Kyrie Irving +165 (20.6)
  • Tyler Thornton +50 (2.8)
  • Josh Hairston +33 (2.1)
*- players must play at least 2 minutes or factor into the box score in some what to be considered for per game E-ratings. Irving (E/8); Thornton (E/18); Hairston (E/16)

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 +22/-3
  • Ryan Kelly +31/-1
  • Miles Plumlee +19/-1
  • Tyler Thornton +9/-2
  • Josh Hairston +15/+0

Notes: Saddled by foul trouble, Ryan Kelly was held without a point, rebound, block, assist, or steal in just six minutes of action. It resulted in a -1 efficiency rating for the sophomore - easily his lowest rating of the season. With so many Blue Devils having big night against Maryland there have been several moves on the season stats. Both Seth Curry and Miles Plumlee moved past Kyrie Irving on the season scores while Nolan Smith upped his per game rating to 21.9 a full 1.3 points over Irving.
