Efficiency Ratings: Bellarmine

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
The 2011-2012 season features a different look and a different style. While there is plenty of fire power in the backcourt, Duke has a number of front court players likely to heavily factor into the offense. That was evident against Bellarmine in the season's first official exhibition game as the Blue Devils pounded their smaller opponents inside to the tune of 40 points from the top three options.

Per minute Efficiency
  • Austin Rivers 0.526
  • Seth Curry 0.581
  • Andre Dawkins 0.133
  • Mason Plumlee 1.087
  • Miles Plumlee 0.950
  • Alex Murphy 0.154
  • Ryan Kelly 0.348
  • Josh Hairston 0.143
  • Tyler Thornton 0.417
  • Quinn Cook 1.091
  • Michael Gbinije 0.286

Notes: The Blue Devils used 11 players against Bellarmine and each had a positive efficiency rating, and a rating above zero. Leading the charge was Mason Plumlee who scored a +25 rating thanks to a perfect night from the field (8-for-8) and, based on last season, no trips to the free throw line. The junior also added nine boards, two steals, and a block. The only 'knock' on Plumlee was three turnovers which lowered his rating a bit. Following his younger brother on the efficiency ratings was Miles Plumlee who added 14 points and eight rebounds to post a +19, just two shy of his season high a season ago. The backcourt was led by Seth Curry's +18. Curry scored well (18 points) and had a very Jon Scheyer-like line of six rebounds, five assists, and three steals. Meanwhile Austin Rivers' Cameron Indoor debut produced a +10 thanks to a line of 13 points and four rebounds. Backing up Curry were Tyler Thornton and Quinn Cook. Cook posted a +12 rating while Thornton added a +10 rating. Both guards valued the ball (2 to 1 a/to ratio) and were able to score when points were available.

This year TDD's adding a per minute efficiency score. In the first exhibition it was Quinn Cook, Mason Plumlee, and Miles Plumlee providing the most 'bang for the buck' in terms of minutes played. Cook's 1.091 was the most efficient per minute performance, while Mason Plumlee was close behind with a 1.087 per minute rating despite playing more than twice the minutes of Cook. Miles Plumlee's 0.950 per minute rate further illustrated Duke's superiority in the paint on this night.
