Efficiency Ratings: Game 26

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.

The Blue Devils have already lost one big time scorer in Irving. On Wednesday night they may as well have lost another as Singler was saddled with foul trouble and offensive inefficiency. Without their senior leader knocking down his usual barrage of shots, Duke relied more on Smith and the post game where Kelly and the younger Plumlee both performed well, combining for 20 points and 14 rebounds between them. Defensively the Blue Devils locked up the Cavaliers after half-time, holding Virginia to just 15 points after intermission.

v. Virginia
(change from previous game)

Notes: As noted, Singler posted his least efficient game of the season with a -1 rating against Virginia. He scored just two points (1-of-5 shooting) while grabbing four rebounds. However the efficiency killer was the 20 percent shooting and five turnovers. Singler wasn't the only Blue Devil who saw his efficiency rating drop either. Seth Curry played a solid game, but his rating dipped below +10 for the first time in two weeks. On the flip side, however, the post game saw the three headed rotation of the two Plumlees and Kelly post a combined +41 rating.

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

Tracking the most and least efficient performances by player

  • Kyrie Irving +35/+12
