Efficiency Ratings: Boston College

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, in 2009 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
After clawing back against NC State at home, Duke faced a potential trap game against the lowly Boston College Eagles. After BC hit its first 5 shots and raced out to a 13-7 lead, Duke's defense clamped down in a big way, holding the hosts without a field goal for more than 13 minutes. By the time the Eagles regained their regular scoring punch, the Blue Devils had built a double-figure lead and were never really challenged en route to a 25 point win.

(change from previous game)


Per minute Efficiency
  • Austin Rivers 0.500
  • Seth Curry 0.593
  • Andre Dawkins 0.423
  • Mason Plumlee 0.059
  • Miles Plumlee 0.458
  • Ryan Kelly 0.333
  • Josh Hairston -0.111
  • Tyler Thornton 0.133
  • Quinn Cook 0.692
  • Michael Gbinije 0.833

Notes: The perimeter trio of Rivers, Dawkins, and Curry was as efficient as they've been (as a group) in quite some time. Curry in particular caught fire in the second half, and would have posted yet another efficiency score over 20 were it note of this team and season high six turnovers. Rivers, playing the fewest minutes he has in more than six weeks, scored well (16), rebounded well (7), and shot well (7-of-13). Dawkins also continued his surge of playing a well-rounded game by hitting for 13 points and five rebounds in just 26 minutes of action.

The perimeter attack was working, but the post game struggled against the Eagles. Mason Plumlee found very early and severe foul trouble that limited him to just 17 minutes on the night. In that time the junior big forward scored just three points and grabbed only three boards while shooting just 1-of-5 from the field. It resulted in his lowest efficiency scored game of the year (+1).

Ryan Kelly also struggled mightily from the field (2-of-8), but managed to find other ways to contribute (eight rebounds, three assists) to post a +10. Meanwhile, Miles Plumlee added a +11 with nine points and 10 boards in 24 minutes.

Off the bench there was a rare Michael Gbinije sighting. The 6'6 wing posted a very efficient +5 in just six minutes (.833/minute).

SEASON HIGH/LOW PERFORMANCES

Tracking the most and least efficient performances by player
  • Austin Rivers +24 / -3
  • Seth Curry +28 / 0

Notes: Seth Curry has been playing as well as any guard in the conference this week and his numbers have reflected it. Curry moves up in the season standings and appears to have an outside shot at catching Ryan Kelly for second place in the seasonal ratings, while also closing in on Quinn Cook for the per/minute fourth place spot.
