Efficiency Ratings: Game 5

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.

A battle of top five teams turned into a one sided affair as Kyrie Irving put together a tremendous performance to power Duke to a rather easy 82-68 victory over the Kansas State Wildcats in Kansas City. The freshman lead guard lead five Blue Devils in double figures as Duke lead by 18 before calling off the dogs late and propelling head coach Mike Krzyzewski to his 800th victory.

(change from previous game)

Notes: After posting the single season high point mark at a +36, Mason Plumlee came back to earth with a +6 efficiency score against Kansas State. The 6'10 sophomore did score 10 points and grab five rebounds, but it was his free throw shooting that lowered his score. Plumlee shot just 50 percent from the line and missed the front end of a few one and ones. It's something that has plagued the Indiana native throughout the season. The best, and most efficient player on the floor Tuesday was Kyrie Irving who took home tournament MVP honors and posted a +21 efficiency mark which was six points higher than the next highest Blue Devil. To make matters more impressive, Irving posted the number against a preseason All-American opponent in K-State's Jacob Pullen (who Irving forced into a miserable offensive night). Off the bench Duke got very efficient performances from Seth Curry (who logged 3 assists and five steals) and Andre Dawkins (who didn't miss a shot). Similarly, Miles Plumlee rebounded from a couple of slow games to post a +8 efficiency number thanks to much improved free throw shooting and a lack of foul trouble.

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

Five Most Efficient Performances

  • Mason Plumlee v. Marquette (+36)
  • Kyrie Irving v. Princeton (+26)
  • Nolan Smith v. Princeton (+25)
  • Kyle Singler v. Princeton (+23)
  • Kyrie Irving v. Colgate (+22)

Five Least Efficient Performances*

  • Tyler Thornton v. Kansas State (-2)
  • Josh Hairston v. Kansas State (+0)
  • Josh Hairston v. Miami (Ohio) (+0)
  • Miles Plumlee v. Princeton (+1)
  • Miles Plumlee v. Miami (Ohio) (+1)
*- players must play at least 2 minutes or factor into the box score in some what to be considered for per game E-ratings

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

  • Kyrie Irving +96 (19.2)
  • Nolan Smith +92 (18.4)
  • Mason Plumlee +82 (16.4)
  • Kyle Singler +68 (13.6)
  • Andre Dawkins +58 (11.6)
  • Seth Curry +54 (10.8)
  • Ryan Kelly +40 (8.0)
  • Miles Plumlee +27 (5.4)
  • Tyler Thornton +14 (3.5)
  • Josh Hairston +8 (2.0)
*- players must play at least 2 minutes or factor into the box score in some what to be considered for per game E-ratings
Notes: The battle for the most efficient season performance continues to flip flop between Irving and Smith on a daily basis. Mason Plumlee, on the strength of his performance in Kansas City, appears to be separating himself from preseason All-American Kyle Singler who has struggled at times from the field. The top seven players are all posting double figure E-ratings per contest with junior big man Miles Plumlee beginning to inch closer towards becoming the eighth player to do so.
