Efficiency Ratings: Game 34

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.

Once again the Blue Devils are the ACC Champion. Once again it was a dominant performance in the championship game. This time, however, it was ever so sweet as Duke blew out North Carolina to take up the team's 30th win of the season and earn a No. 1 seed in the NCAA Tournament. The team may not have been as efficient as in other games on the offensive end, but that was mitigated in a big way thanks to ramped up defensive pressure. All in all the Duke defensive pressure held North Carolina to just 34 percent from the field and 25 percent from behind the arc. Duke also got superior point guard play from Nolan Smith who posted a double-double while holding Kendall Marshall to just 4 assists and five turnovers and 3-of-10 from the field..

Notes: Smith was brilliant. Once again the senior hit above his efficiency per game average. Singler was gutty and though his rating was down significantly from the semifinals, he made plays when he had to. And in many ways that didn't show up in the box score. Singler scored and rebounded (11 and 8), but his poor shooting percentage (5-of-14) and turnovers (4) were the killers in this equation. Duke got a big lift from the post against an NBA sized frontline from Carolina with the Plumlees and Kelly combining for 35 points including Kelly's +15 rating. Miles Plulmee's +12 was courtesy of his rebounding (7) and shooting (4-4). Meanwhile Duke also got a great boost from Andre Dawkins (+9) and Seth Curry (+12) both of whom shot the ball well (combined 7-of-10).

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)
  • Kyle Singler v. Maryland (+34)
  • 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)

Five Least Efficient Performances*
  • Nolan Smith v. Miami (-6)
  • Andre Dawkins v. Miami (-4)
  • Andre Dawkins v. Miami (-4)
  • Tyler Thornton v. Miami (-4)
  • Seth Curry v. Miami (-3)
*- players must play at least 3 minutes or factor into the box score to be considered for per game E-ratings
Cumulative Season ratings for the Blue Devils. (E/game)*

  • Nolan Smith +666 (19.6)
  • Kyle Singler +549 (16.1)
  • Mason Plumlee +485 (14.3)
  • Ryan Kelly +344 (10.1)
  • Seth Curry +324 (9.5)
  • Miles Plumlee +254 (7.5)
  • Andre Dawkins +246 (7.2)
  • Kyrie Irving +165 (20.6)
  • Tyler Thornton +78 (2.9)
  • Josh Hairston +34 (1.8)
*- players must play at least 3 minutes or factor into the box score to be considered for per game E-ratings. Irving (E/8); Thornton (E/27); Hairston (E/18)

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: Miles Plumlee puts a bit of distance between himself and Dawkins thanks to a strong shooting and rebounding night against Carolina. Similarly, Ryan Kelly's night pushed him further away from Seth Curry. Kelly now owns a +20 advantage over Curry. There is still a chance that Nolan Smith will regain the per game lead if the rumors of Kyrie Irving returning for the NCAA Tournament prove to be true.
