Efficiency Ratings: Game 24

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 tale of two halves in Cameron. The first was dominated by the Tar Heels as John Henson and Tyler Zeller looked like men against boys in the paint while freshman Kendall Marhsall sliced up the Duke defense before finding his teammates for easy assists. It was enough for the Blue Devils to trail by 14 at the half. After some crucial adjustments by head coach Mike Krzyzewski at intermission, the Blue Devils out-scored the Tar Heels by 20 in the second half to rally and take a six point victory in one of the storied rivalry's best games.

Notes: There isn't much that can be said at this point regarding the play of Nolan Smith. The junior guard was flat out amazing against the Tar Heels. When Duke couldn't find a reliable ball handler, Smith slid over to the point and took over that duty as well. And while brilliance has become the standard for Nolan, it took a brilliant offensive performance from Seth Curry to supplement and carry the Blue Devil attack. Curry hit 67 percent of his shots (8-12) and also managed to rebound (6) and hand out assists (5) while valuing the basketball (2 TOs). Meanwhile, the Blue Devils didn't get anything from the post early, but Miles Plumlee was big in the second half and finished with a double figure efficiency score. On the negative side, it was a forgettable shooting night for Kyle Singler (3-of-17) which resulted in the senior posting his lowest score of the season.

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

Ten Most Efficient Performances

  • Mason Plumlee v. Marquette (+36)
  • Nolan Smith v. UNC-Greensboro (+36)
  • Kyrie Irving v. Michigan State (+35)
  • Nolan Smith v. Miami (+31)
  • Nolan Smith v. UAB (+31)
  • Ryan Kelly v. Wake Forest (+31)
  • Nolan Smith v. Virginia (+30)
  • Nolan Smith v. St. John's (+30)
  • Nolan Smith v. Boston College (+29)
  • Kyle Singler v. UNC-Greensboro (+29)
  • Mason Plumlee v. North Carolina State (+27)

Five Least Efficient Performances*

  • Tyler Thornton v. Miami (-4)
  • Seth Curry v. Miami (-3)
  • Seth Curry v. Michigan State (-2)
  • Tyler Thornton v. Kansas State (-2)
  • Tyler Thornton v. Virginia (-2)
*- players must play at least 3 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)*

  • Nolan Smith +512 (21.3)
  • Kyle Singler +390 (16.3)
  • Mason Plumlee +330 (13.8)
  • Ryan Kelly +237 (9.9)
  • Andre Dawkins +222 (9.3)
  • Seth Curry +209 (8.7)
  • Miles Plumlee +183 (7.6)
  • Kyrie Irving +165 (20.6)
  • Tyler Thornton +45 (2.3)
  • Josh Hairston +34 (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. Irving (E/8); Thornton (E/20); Hairston (E/17)

Tracking the most and least efficient performances by player

  • Kyrie Irving +35/+12
  • Nolan Smith +36/+4
  • Mason Plumlee +36/+0
  • Kyle Singler +29/+3
  • Andre Dawkins +23/-1
  • Seth Curry +27/-3
  • Ryan Kelly +31/-1
  • Miles Plumlee +19/-1
  • Tyler Thornton +9/-4
  • Josh Hairston +15/+0

Notes: Curry posted his best score of the season and becomes the sixth Duke player to post a +25 efficiency rating in a single game this season. As noted above there is simply nothing left to be said of Nolan Smith's play. The senior has locked up the ACC Player of the Year award after 10 games and now the push for National Player of the Year will commence. As Duke moves forward it'll be crucial to get Singler back in rhythm along with Ryan Kelly who has gone from can't miss to struggling from the field (though he did knock down a huge three in the second half).
