Efficiency Ratings: Game 7

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.

In what many analysts see as a possible preview of the National Championship game in Houston, the Blue Devils used a terrifc performance from their freshman phenom point guard to beat Michigan State 84-79 as part of the annual ACC/Big 10 Challenge.

v. Michigan State
(change from previous game)

Notes: To say Irving was great may not adequately describe what the 6'2 freshman was able to do. His +35 efficiency rating is just one off the seasonal high mark posted by Mason Plumlee against Marquette. Duke certainly needed the improved performance as Irving was the only Blue Devil to post a positive change in his efficiency ratings from the previous game against Oregon. Obviously the much tougher opponent plays a role here, but various Blue Devils struggled in different areas. One noticeable slump in terms of efficiency rating has been that of Seth Curry who posted this third 0 or lower rating in the last four games, though his minutes were far more sparse on Wednesday than in the previous two.

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

Ten Most Efficient Performances

  • Mason Plumlee v. Marquette (+36)
  • Kyrie Irving v. Michigan State (+35)
  • Kyle Singler v. Oregon (+27)
  • Kyrie Irving v. Princeton (+26)
  • Nolan Smith v. Princeton (+25)
  • Kyrie Irving v. Princeton (+23)
  • Kyrie Irving v. Colgate (+22)
  • Kyrie Irving v. Princeton (+20)
  • Nolan Smith v. Miami (+20)
  • Nolan Smith v. Marquette (+19)

Five Least Efficient Performances*

  • Seth Curry v. Michigan State (-2)
  • Tyler Thornton v. Kansas State (-2)
  • Josh Hairston v. Kansas State (+0)
  • Josh Hairston v. Miami (Ohio) (+0)
  • Seth Curry v. Oregon (+0)
  • Tyler Thornton v. Oregon (+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

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

  • Kyrie Irving +148 (21.2)
  • Nolan Smith +122 (17.4)
  • Mason Plumlee +113 (16.1)
  • Kyle Singler +108 (15.4)
  • Andre Dawkins +75 (10.7)
  • Seth Curry +52 (7.4)
  • Ryan Kelly +52 (7.4)
  • Miles Plumlee +42 (6.0)
  • Tyler Thornton +14 (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
Notes: Irving begins to separate himself from the rest of the pack - building a 26 point lead over Nolan Smith. Inside the Blue Devils continue to get strong performances from Mason Plumlee with the secondary post combination of Ryan Kelly and Miles Plumlee combining for a +94 seasonal rating. Speaking of Kelly, he's steadily moving up the efficiency board having caught Seth Curry for seasonal output.
