Efficiency Ratings: Michigan St.

Using the NBA Efficiency Rating Formula, TDD tracks the best statistical performances of 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.


LATEST GAME
In their first game against a high major opponent, the Blue Devils used a balanced but blue collar attack to build a 20 point cushion before holding off a late Michigan State rally to win 74-69. The victory earned head coach Mike Krzyzewski his record setting 903rd win, while also featuring a coming out part of sorts for Dawkins who finished with 26 points. The performance from the junior guard was needed as several of the early season efficiency leaders struggled against the rugged Spartan defense.

Per minute Efficiency
  • Austin Rivers -0.087
  • Seth Curry 0.737
  • Andre Dawkins 0.684
  • Mason Plumlee 0.219
  • Miles Plumlee 0.071
  • Alex Murphy 0.00
  • Ryan Kelly 0.633
  • Josh Hairston -0.200
  • Tyler Thornton 0.000
  • Quinn Cook 0.000
  • Michael Gbinije 0.000

Notes: Andre Dawkins stole the show with some dynamite three point shooting at critical times. For the game Dawkins finished with 26 points and three rebounds to go with four steals. He was efficient with his shooting (8-of-15 overall) and managed to stay on the floor for extended periods for the first time all season. Fellow guard Seth Curry put together his best overall performance of the season with 20 points, seven rebounds, four assists, and four steals. The two guards combined for a +54 efficiency rating on the night and were clearly the difference between the two teams.

In the post Duke struggled to find any consistency, but the Plumlee brothers both had moments of effectiveness. Mason Plumlee registered his lowest rating of the season with a +7, a score that was brought down tremendously by downturns in his points (7), rebounds (5), and assists (1) compared to previous games. Meanwhile, captain Miles Plumlee managed to factor in on the boards (4) but not in the scoring column (1) while struggling with turnovers throughout the evening. Both players did alter several shots and helped hold the MSU FG pct low for most of the game.

Super sixth man Ryan Kelly continues his steady performances and may be making a case as the nation's top sub. Kelly didn't miss a shot all night (FG & FT) and finished with 14 points and four rebounds. Kelly again posted a double digit efficiency rating (+19) and continues to move up the seasonal rankings.

One Blue Devil who struggled mightily was Austin Rivers. The freshman's first two performances had been inconsistent at times and Tuesday night's game saw his numbers fall off a cliff on a big stage. Rivers posted a -2 rating (a 20 point drop from the last game) while being limited to just 23 minutes after he shot just 1-of-7 from the field and committed two turnovers. In addition to his shot not falling, Rivers failed to factor much into the defensive statistics by registering just 1 rebound and one steal in 23 minutes.
