Efficiency Ratings: Game 27

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.

Another slow start got an unexpected shot in the arm when head coach Mike Krzyzewski received a technical foul midway through the first half. From that point on the Blue Devils were able to grab control of the game and eventually push the lead to nearly 30 points before cruising to an easy 22 point decision over Georgia Tech. As a team the Blue Devils made 28 shots on the night and recorded assists on 18 of those.

Notes: Aside from Smith's usual brilliance, the Blue Devils enjoyed a balanced attack with six players recording double figure efficiency ratings. Most notable of those half dozen players was Kyle Singler who responded with a +15 performance after recording a -1 against Virginia in his last game. Singler still struggled from the field (5-of-14), but was able to contribute on the glass with a team high nine rebounds. Additionally, Tyler Thornton played his most efficient game of the season with a +12 rating in 24 minutes of action. Thornton scored six points, grabbed three rebounds, handed out two assists, and grabbed two steals in his most efficient outing of the season. And while the freshman produced in a big way, much of his earned playing time seemed to come at the expense of sophomore Andre Dawkins who recorded a -2 rating in just nine minutes of action.

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

Five Least Efficient Performances*

  • Andre Dawkins v. Miami (-4)
  • Tyler Thornton v. Miami (-4)
  • Seth Curry v. Miami (-3)
  • Andre Dawkins v. Georgia Tech (-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 +576 (21.3)
  • Kyle Singler +422 (15.6)
  • Mason Plumlee +382 (14.1)
  • Ryan Kelly +281 (10.4)
  • Seth Curry +250 (9.3)
  • Andre Dawkins +220 (8.1)
  • Miles Plumlee +200 (7.4)
  • Kyrie Irving +165 (20.6)
  • Tyler Thornton +65 (2.8)
  • Josh Hairston +33 (1.8)
*- 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/23); Hairston (E/18)

Tracking the most and least efficient performances by player

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

Notes: Duke has a solid five man rotation from the efficiency rating standpoint. As Curry continues to emerge on the offensive end, the Blue Devils have five players averaging a 9.3 efficiency per game or higher. Quietly, Mason Plumlee has inched up the leader board and is within striking distance of second play in the season standings though overtaking Kyle Singler is a long shot with a maximum of 13 games remaining in the season. On the somewhat darker side of the victory is the reduced role played by Andre Dawkins who has struggled to earn court time over the last few weeks.
