Efficiency Ratings: Kentucky

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.

It was a big test in the second game of the year as the Blue Devils faced off against the third ranked Kentucky Wildcats in Atlanta. Duke used the steady play of its seniors down the stretch to halt a Kentucky rally which reduced a 14 point margin to just three. Seth Curry scored a game high 23 points, while Mason Plumlee added 18 points in the victory. With Plumlee in foul trouble, Duke got an unexpected life off the bench from Josh Hairston who came in and provided crucial offensive rebounds and defense.

(change from previous game)

Notes: Plumlee's rating took a dive after the senior big man was limited to just three rebounds on the night. Meanwhile, Curry's rating nearly tripled thanks to an efficient shooting night (50 percent from the floor and 100 percent from the free throw line), and zero turnovers. Freshman Rasheed Sulaimon's tough shooting night (3-of-14) reduced his score by one point. The 11 missed shots negated a very good all around stat line that included six rebounds and five assist against zero turnovers.

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

Cumulative Season ratings for the Blue Devils. (E/game)*

Tracking the most and least efficient performances by player

  • Mason Plumlee: 29/21
  • Quinn Cook: 8/7
  • Tyler Thornton: 15/6
  • Rasheed Sulaimon: 10/9
  • Ryan Kelly: 10/10
  • Seth Curry: 22/8
  • Amile Jefferson: 7/1
  • Alex Murphy: 0/
  • Marshall Plumlee: DNP
  • Josh Hairston: 8/-1

Notes: Plumlee continues to stretch his lead in both the cumulative totals and per minute scoring. Seth Curry's big game moved him into second place in the season totals, but Amile Jefferson's lack of minutes has him higher in per minute scoring average. A point of concern on the offensive end has to be the efficiency scores of Ryan Kelly, who finished second in the standings a season ago. The 6'10 senior is still struggling with his outside shot and rebounding totals which has led to the lowest efficiency rating of the five starters.
