Efficiency Ratings: Virginia Tech

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, in 2009 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
There was no time to celebrate a big victory against Florida State as Duke had approximately 36 hours to prepare for a feisty and somewhat desperate Virginia Tech team. The Hokies, knowing that Duke would enter the game somewhat fatigued, employed a very physical style in hopes of wearing the Blue Devils down. It certainly worked as Virginia Tech took the lead down the stretch only to see Duke force overtime before pulling away in the final seconds.

Per minute Efficiency
  • Austin Rivers 0.317
  • Seth Curry 0.350
  • Andre Dawkins -0.500
  • Mason Plumlee 0.520
  • Miles Plumlee 0.485
  • Ryan Kelly 0.290
  • Josh Hairston 0.000
  • Tyler Thornton 0.237
  • Quinn Cook 0.167
  • Michael Gbinije 0.000

Notes: Just one game after seeing Andre Dawkins carry the Blue Devils over Florida State, the junior disappeared. Dawkins missed all three of his shot attempts and turned the ball over another three times while earning just 10 minutes against Virgina Tech. Against the Seminoles Dawkins register a +19 and .905/minute efficiency score. Against Virginia Tech those numbers were the polar opposite with Dawkins registering a -5 score and a per minute rate of -.500.

Inside Duke got much needed production from Mason Plumlee who scored seven points and grabbed nine rebounds to post a +13 score. As the team's most productive/efficient player on the year, Plumlee had scored just a +2 over the last two games. Against VT, however, he put up a +13 and a .520/minute score in 25 minutes of action. Miles Plumlee, meanwhile, didn't score in bunches (5 points), but did hit the boards hard (15) en route to a +16.
