Efficiency Ratings: Game 3

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.

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
The Blue Devils used an early second half surge to register a third straight blow-out victory. The latest victim coming in the form the Patriot League's Colgate Raiders. Duke overwhelmed their smaller opponents on both ends of the floor, holding the Raiders to just 30.9 percent shooting from the field while seeing nine Blue Devils score nine points or more.

Notes: Miles Plumlee had his most efficient game of the season with a +14 rating. In the previous two games the elder Plumlee had registered just a +1 rating. Meanwhile freshman Kyrie Irving continues to shine, leading the Blue Devils with a +22 performance despite playing just over half the available minutes. As a team the Blue Devil attack mirrored the overall efficiency rating as eight of the 10 rotational players logged double figure E-ratings which corresponded with eight of 10 players scoring nine or more points. Perhaps the most crucial group showing improvement was the post where, aside from Miles Plumlee, Ryan Kelly and Mason Plumlee registered +15 and +13 ratings respectively. The younger Plumlee's +13 was limited to foul trouble as he was disqualified after playing just 13 minutes.

MEMORABLE SEASON PERFORMANCES
Throughout the season TDD will track the various highs and lows using the formula.

SEASON EFFICIENCY RATING
Cumulative Season ratings for the Blue Devils. (E/game)

  • Nolan Smith +61 (20.3)
  • Kyle Singler +47 (15.7)

Notes: Irving takes over the top efficiency spot from Nolan Smith after posting 13 points, 9 assists and no turnovers against Colgate. Meanwhile the Blue Devils' balance and depth is showing up as six players are averaging double figure efficiency points per contest. The elder Plumlee's big effort against Colgate pushed him above freshmen Tyler Thornton and Josh Hairston. With the Blue Devils heading to play Marquette next week it'll be interesting to see how these numbers change as the competition ramps up considerably.
