Efficiency Ratings: Game 32

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.

Before the game Duke faithful got teased by a view of Kyrie Irving running up and down the court. He didn't play because of a toe injury. With eight minutes to go Duke fans held their collective breath as another toe, the second on Smith's left foot, sent the ACC Player of the Year to the bench for the rest of the game. From there the Blue Devil offense diversified as well as it has all year as Duke pulled away from Maryland down the stretch to win by 16 in the ACC quarterfinals..

Notes: After leading the team in most every game this season and especially since Irving went down, Nolan Smith had the most inefficient game of the season. By any Duke player (-6). Smith struggled from the field (2-of-11) and didn't record any rebounds while handing out just two assists. The poor field goal percentage hurt his rating, but the five turnovers killed it. On the flip side all the questions about where Kyle Singler was hiding have been answered. Singler was aggressive off the bounce and overcame continued struggles from the perimeter to post his best game of the season with a +34 rating. Singler scored 29 points, grabbed nine rebounds and shot the ball well (10-of-15). He also committed just two turnovers. In the paint Duke got a big performance from all three of the primary post players as Mason Plumlee, Miles Plumlee, and Ryan Kelly combined to post a +49 rating. Mason had 10 points, 11 rebounds, and five assists resulting in a +23 mark. Miles added eight offensive boards for Duke to post a +14 while Kelly found his shot (5-of-5 FG) to post a +12.

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
  • Nolan Smith +36/-6
  • Mason Plumlee +36/+0
  • Kyle Singler +34/-1
  • Andre Dawkins +23/-4
  • Seth Curry +27/-3
  • Ryan Kelly +31/-1
  • Miles Plumlee +19/-2
  • Tyler Thornton +12/-4
  • Josh Hairston +15/-1

Notes: On a night where Singler posted his best night of the season, Smith posted his worst and was saddled with a jammed toe that may keep him out of tomorrow's game against either Virginia Tech or Florida State. While the injury has many Blue Devil fans worried, there is optimism after seeing the performances of Curry, Dawkins, Kelly, and the Plumlees. For the first time in quite a while the Blue Devils were balanced and showed the ability to control tempo and get buckets from all over the floor. For the season, Smith's bad night will probably cement Kyrie Irving's per game rating as the highest…unless Irving returns for spot duty at some point in the next few weeks. Similarly, Andre Dawkins and Miles Plumlee seemed destined to clash for the 6th spot in the season's cumulative ratings. The two players are just three points apart. Given Plumlee's ability to rebound, Dawkins will likely need to continue shooting well in order keep the elder Plumlee at arm's length as the season winds down.
