Efficiency Ratings: Game 28

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 a several week shooting slump, Singler went inside early and often for Duke. The result was a game high 28 points on better than 50 percent shooting from the floor as the Blue Devils overcame another slow offensive start to blow out another opponent in Cameron Indoor Stadium. One of the sparks to overcoming the sluggish first half performance was Thornton who came of the bench and scored six quick points for the Devils to help build a working margin before halftime. After intermission Temple ran out of stamina and fresh bodies as Duke continued to apply the pressure and pull away.

Notes: This was, from an efficiency standpoint, Singler's second best performance of the season - just one point short of his +29 rating against UNC-Greensboro in December. Duke also got a continued lift from Mason Plumlee who didn't score a lot (6 points), but did manage 13 rebounds, 2 assists, 2 steals, and a block while shooting 60 percent from the field. For his efforts, the younger Plumlee finished with a +18 rating. On the flip side, the elder Plumlee posted a season low -2 rating while playing just four minutes that resulted in two fouls, a missed shot, and a turnover. Similarly struggling was senior Nolan Smith who couldn't find the range from the field (5-of-17 FG) and seemed to be pressing on the offensive end at times. Bouncing back to the positive, however, Andre Dawkins played sparingly (7 minutes), but did manage to post a +6 rating while making every shot he attempted in those limited minutes.

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

  • Tyler Thornton v. Miami (-4)
  • Seth Curry v. Miami (-3)
  • Andre Dawkins v. Georgia Tech (-2)
  • Miles Plumlee v. Temple (-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 +585 (20.9)
  • Kyle Singler +450 (16.1)
  • Mason Plumlee +400 (14.3)
  • Ryan Kelly +295 (10.5)

  • Andre Dawkins +226 (8.1)
  • Miles Plumlee +198 (7.1)
  • Kyrie Irving +165 (20.6)
  • Tyler Thornton +73 (3.0)
  • Josh Hairston +34 (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/24); 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/-2
  • Tyler Thornton +12/-4
  • Josh Hairston +15/-1

Notes: As noted above the game against Temple was the least efficient offensive performance posted by Miles Plumlee this season. Two quick fouls and poor match-ups limited the 6'10 junior to just four minutes of action. However, it was Singler's second most efficient performance of the season and moved the Oregon native above +16/game in the efficiency ratings. Nolan Smith's +9 was entirely respectable, but reduced his per game average to under 21/game for the first time in a few weeks. It's more a testament to how good Smith has been throughout the season than a reflection on him having an off night that was still, on average, in the top five on a nightly basis.
