Efficiency Ratings: Washington

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

The Blue Devils returned to Madison Squre Garden for a Saturday afternoon matchup against the Washington Huskies. For most of the afternoon Duke looked the part of a top five team, racing out to a big lead before Washington got hot and Duke went stone cold from the free throw line to provide a little bit of drama down the stretch. When the game entered crunch time, however, the Blue Devils were able to make six of eight from the charity stripe to put the game away. A last second three pointer from the Huskies closed the final score to 86-80.

v. Washington
(change from previous game)

Per minute Efficiency
  • Austin Rivers 0.600
  • Seth Curry 0.167
  • Andre Dawkins 0.438
  • Mason Plumlee 0.433
  • Miles Plumlee 0.950
  • Ryan Kelly 0.667
  • Josh Hairston 0.000
  • Tyler Thornton 0.100
  • Quinn Cook 0.500
  • Michael Gbinije 0.000

Notes: For much of the first half it appeared as though junior Ryan Kelly would continue his string of low efficiency performances following his great run of games in Maui. Kelly missed his first eight shots from the field, but found his range after halftime. The 6'10 junior also crashed the boards on the weak side, providing much needed help to Mason Plumlee in the paint, to finish with eight boards. Despite the low shooting percentage (6-of-15), Kelly's all around floor game of eight rebounds and three steals to go with 16 points resulted in a +18 rating.

And speaking of low shooting percentages, Mason Plumlee's day at the free throw line could certainly be classified as such. The junior, who scored 12 points and grabbed nine rebounds along with three steals and two blocks, managed just 2-of-11 from the charity stripe. Shooting a respectable 67 percent from the line would have resulted in not only a much higher rating (+13), but also the game being academic down the stretch instead of somewhat close. On the flip side, brother Miles Plumlee continued his stretch of effective and efficient play off the bench, earning a team-high +19 thanks to nine points, seven rebounds, and three blocks in just 20 minutes of action.

Newly minted sixth man, Andre Dawkins, came off the bench to score 17 points while rating out at a +14. It was a shot in the arm to a backcourt that saw two starters (Curry and Thornton) combine for just a +8 combined in 60 minutes.
