Efficiency Ratings: Game 29

Using the NBA Efficiency Rating Formula, TDD tracks the best statistical performances of the season

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.

Sometimes the shots don't fall. But on Saturday night in Blacksburg it was worse than that. The shots didn't fall, but the Blue Devils also couldn't get an attempt off in the final 27 seconds of the game. To make matters worse for Duke, the Blue Devils seemed to have the game in hand before melting down as the game hit the final stretch as Virginia Tech rallied from six down and gained momentum to earn that program's biggest victory in years. For Duke it was another cold shooting night from Singler (6-of-19) paired with an inability for a third scorer to be found that resulted in a third loss in 29 games.

Notes: Despite his cold shooting, Singler showed why he is such a versatile player in posting a +19 efficiency rating despite struggling tremendously from the field. Additionally the Bleu Devils got another steady performance from Mason Plumlee in the post with a +17 rating. The younger Plumlee posted 9 points, 7 rebounds, a steal and a couple of blocks. Meanwhile Nolan Smith scored and rebounded (18 and 7), but didn't log many assists. That was actually a theme for most of the night as Duke recorded just 6 assists on 23 made shots for the evening.

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

  • Tyler Thornton v. Miami (-4)
  • Seth Curry v. Miami (-3)
  • Seth Curry v. Virginia Tech (-3)
  • 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 +601 (20.7)

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: On a night where it was pointed out over and over that his dad was a Virginia Tech all-time great, Seth Curry posted his least efficient game of the season. The sophomore missed all his field goal attempts and fouled out in less than 10 minutes of action to post a -3 rating. On the season Nolan Smith is in danger of losing his per game efficiency rating lead to Kyrie Irving. Meanwhile Mason Plumlee has steadily improved his season total and his per game total.
