Efficiency Ratings: Shaw

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.


LATEST GAME
In the last exhibition game of the season Duke faced an undersized, but very fast Shaw team. Being early in the season the Blue Devils struggled with help defense which allowed their opponents to stay in the game quite a while longer than expected while shooting 46 percent from the field. Additionally, Duke left number of points on the court thanks to failures to convert close chances and extremely poor free throw shooting (11-of-24 as a team). Still, the Blue Devils were able to pull away midway through the second half, building a 20 point lead with just over seven minutes remaining before coasting to an 80-66 victory.

Per minute Efficiency
  • Austin Rivers 0.333
  • Seth Curry 0.462
  • Andre Dawkins 0.522
  • Mason Plumlee 0.857
  • Miles Plumlee 0.320
  • Alex Murphy 0.667
  • Ryan Kelly 0.870
  • Josh Hairston 0.455
  • Tyler Thornton 0.063
  • Quinn Cook -0.154
  • Michael Gbinije 0.222

Notes: The continued deep bench and ever-changing rotations seemed to disrupt the flow of the game as head coach Mike Krzyzewski continues to search out and experiment with a roster featuring 11 rotational players. Several players saw their efficiency rating drop from the opening game, none more so than freshman Quinn Cook who posted a -2 rating after beginning his career in Cameron with a +14 against Bellarmine. Similarly, fellow back-up point guard Tyler Thornton added a +1 performance after posting a +10 in the first game. The post game cooled off in pockets, but the trio of Miles Plumlee (+8), Mason Plumlee (+18), and Ryan Kelly (+20) still acquitted themselves very well and continued to drive home the point that Duke will be an inside-outside team in 2011-2012. Kelly and Mason Plumlee were the most efficient players on the afternoon with both posting extremely high per minute scores of .857 and .870. The next closes player (playing extended minutes) was Andre Dawkins who rebounded from a sluggish opening night to post a +12 rating in 23 minutes (.522).
