Efficiency Ratings: Wake Forest

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
Before the ball was tipped there was some interesting stories leaking out of Durham. Head coach Mike Krzyzewski changed the starting lineup again, benching Kelly and Rivers in favor of Quinn Cook and Miles Plumlee. Was it a wakeup call to the duo? Perhaps. It certainly seemed to be as both player scored 20 points as the Blue Devils powered past Wake Forest with relative ease.

Per minute Efficiency

Notes: A game after seeing the inside game take control, Duke got a huge bump from the perimeter players as Rivers, Curry, and Dawkins combined for a +47 efficiency score. The trio combined for 55 points on 20-of-33 shooting from the floor. Dawkins in particular had a big night, hitting 7-of-9 from the perimeter and posting a very high .615 per minute score.

After being benched both Ryan Kelly and Austin Rivers posted much improved scores with Rivers hitting for a +16 score and Kelly posting the most efficient game of the season with a +30 thanks to productive numbers in points (20), rebounds (10), assists (4), shooting percentage (8-of-11), and free throw shooting percentage (4-of-5).
