Efficiency Ratings: Game 25

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.

With a first half injury to Smith, the Blue Devils worked hard to balance the offense. The effort paid off as five players scored nine or more points as Duke posted a workmanlike victory in Coral Gables. Duke shot 50 percent from the field and 42 percent from the perimeter. Additionally the Blue Devils posted 17 assists on 28 made baskets.

(change from previous game)

Notes: Smith played a season low 27 minutes due to the eye injury in the first half. Despite just two points before intermission the senior managed to post a nice stat line of 18 points and five assists. Fellow Tar Heel killer, Seth Curry, got the start and responded with another great all around floor game with 16 points, four rebounds and five steals. As a team the Blue Devils saw all five starters post double figure efficiency ratings while Miles Plumlee and Tyler Thornton both posted +9 ratings off the bench. On the flip side the Blue Devils have to be concerned about sophomore swingman Andre Dawkins who posted a -4 rating after missing all four shots against the Hurricanes.

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)

Five Least Efficient Performances*

  • Andre Dawkins v. Miami (-4)
  • Tyler Thornton v. Miami (-4)
  • Seth Curry v. Miami (-3)
  • Seth Curry v. Michigan State (-2)
  • Tyler Thornton v. Kansas State (-2)
*- 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 +528 (21.2)
  • Kyle Singler +408 (16.3)
  • Mason Plumlee +348 (13.9)
  • Ryan Kelly +247 (9.9)
  • Seth Curry +228 (9.1)
  • Andre Dawkins +218 (8.7)
  • Miles Plumlee +192 (7.7)
  • Kyrie Irving +165 (20.6)
  • Tyler Thornton +54 (2.6)
  • Josh Hairston +34 (2.0)
*- 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/21); Hairston (E/17)

Tracking the most and least efficient performances by player

  • Kyrie Irving +35/+12
  • Nolan Smith +36/+4
  • Mason Plumlee +36/+0
  • Kyle Singler +29/+3
  • Andre Dawkins +23/-4
  • Seth Curry +27/-3
  • Ryan Kelly +31/-1
  • Miles Plumlee +19/-1
  • Tyler Thornton +9/-4
  • Josh Hairston +15/+0

Notes: Curry's strong run of games has allowed him to jump over Dawkins in both the rotation and the season efficiency ratings. As for the Virginia sophomore, he has struggled over the last few games and posted his least efficient performance of the night against Miami. While the shooting percentages will come and go, it's Dawkins' inability to factor in the other statistical categories (rebounds, assists, steals, blocks, etc) that has hurt his ratings. Meanwhile, it's no secret that Nolan Smith is going to finish the season as the team's most efficient player. The only drama will be by how much.
