Efficiency Ratings: Wake Forest

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.

Battling foul trouble and a raucous environment in Winston Salem, the Blue Devils rode a career night from Plumlee to the team's first true road win of the season. Additionally, Duke got a huge lift from classmate, Curry who scored 21 points including a tie-breaking three in the final moments. Duke moved to 5-2 on the season in conference play, and 18-2 on the year.

v. Wake Forest
(change from previous game)

  • Mason Plumlee +35 (+12)
  • Seth Curry +14 (+3)
  • Ryan Kelly -- (--)
  • Quinn Cook +13 (-4)
  • Tyler Thornton +1 (-6)
  • Rasheed Sulaimon +7 (-16)
  • Amile Jefferson +2 (-13)
  • Alex Murphy +2 (+2)
  • Josh Hairston +4 (--)
  • Marshall Plumlee 0 (-1)

Notes: Plumlee's biggest day of the season could have been bigger were it not for three phantom offensive fouls that resulted in a season high seven turnovers. If you eliminate those three fouls, Plumlee would have recorded a +38. And it wasn't just the high point total that did the trick either. Mason added nine rebounds, missed just three of 15 shots, and just two of 10 free throws.

After Plumlee, the Blue Devils didn't get a lot of high efficiency scores for various reasons. Amile Jefferson scored just a +2 after recording a +15 against Maryland. Jefferson was held scoreless and grabbed just a handful of rebounds in 19 minutes. Similarly, Rasheed Sulaimon came back down to earth in a macro sense, hitting just a +7 after getting 16 more points against Maryland. Still, it's hard to imagine it's a concern after Sulaimon hit a bit, game clinching shot with less than a minute remaining.

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

Tracking the most and least efficient performances by player

  • Mason Plumlee: 35/9
  • Quinn Cook: 36/6
  • Tyler Thornton: 16/-3
  • Rasheed Sulaimon: 16/-6
  • Ryan Kelly: 23/10
  • Seth Curry: 26/-8
  • Amile Jefferson: 15/0
  • Alex Murphy: 13/0
  • Marshall Plumlee: 2/0
  • Josh Hairston: 9/-1

Notes: Curry and Sulaimon are in a dead heat in the season efficiency rating. Sulaimon is making up the substantial scoring gap (70 points) by winning several other categories including assists, rebounds, steals, and more.

The battle to replace Ryan Kelly sees Amile Jefferson scoring better in these offensive efficiency ratings, but Josh Hairston has made a number of hustle plays that have 'earned him some equity' according to Coach K.
