Efficiency Ratings: NC State

Cook and Plumlee

Using an 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.


LATEST GAME
For the second game in a row, the Blue Devils started fast and never allowed their opponent to catch up. Duke raced out a big early lead thanks to hot shooting and high pressure defense, leading by 21 at the half. NC State would battle back throughout the second half, and would close to within single digits, but a short bench and foul trouble prevented the Wolfpack from getting any closer as Coach K's squad moved to 7-2 in conference play.

Notes: After playing limited minutes against Florida State, Mason Plumlee provided Duke a big presence in the post, scoring 30 points for the second time in the last three games, while also grabbing nine rebounds. It resulted in a +36 score largely due to the shooting percentages (9-11 from the floor & 12-of-16 from the free throw line). Plumlee showed off a number of post moves and freed himself up for easy finishes throughout the night.

Cook was the second most efficient Blue Devil, again due more to the shooting percentages more than other statistics. The sophomore point guard hit six of eight from the floor and five of six from the free throw line. He also added four assists and a block against just one turnover.

Curry's +22 was due in large part to his shooting from the free throw line (10-of-12), his 4-to-1 assist to turnover ration, and his total points (26). The score would have been higher, but the senior struggled from the field (as did most of the Blue Devils) after halftime, leaving his game total at 6-of-15.

In the per minute category, Plumlee scored a .900 per minute offensive efficiency rating while Cook was at .743.
