Efficiency Ratings: Ohio State

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
Take a young team playing its seventh games in 13 days, add in the nation's most complete opponent playing its best game of the year, and mix in some extremely forgettable performances from the aforementioned team's top rotation and you have a recipe for disaster. That's exactly what happened as Duke was crushed on national television by Ohio State in a game that will almost certainly require quite a bit of film study and reexamination by the coaching staff and players.

Per minute Efficiency
  • Austin Rivers 0.351
  • Seth Curry 0.000
  • Andre Dawkins 0.000
  • Mason Plumlee 0.486
  • Miles Plumlee 0.529
  • Ryan Kelly 0.067
  • Josh Hairston 0.538
  • Tyler Thornton -0.125
  • Quinn Cook 0.286
  • Michael Gbinije 0.313
  • Alex Murphy 0.000

Notes: To say the game against Ohio State was forgettable for the trio of Curry, Dawkins, and Kelly would be an understatement. The three players who had helped carry Duke in Maui combined to score a +1 in 60 minutes total. Whether it was Ohio State's length and athleticism all over the floor, or perhaps a situation of former role players not ready to compete with the nation's elite opponents, the three players Duke absolutely needed big games from couldn't answer the call.

With 60 percent of the starting lineup failing to factor into the game on the offensive end, Duke was able to get big time performances from Austin Rivers and Mason Plumlee who combined for a +30 rating between them. Once again Plumlee's biggest setback came at the free throw line where he shot just 2-of-5, en route to a +17 rating. Rivers' +13 was held down due to a high number of field goal attempts (18) relative to points (22).

Off the bench Duke got a career best +5 from Michael Gbinije and +4 from Quinn Cook. Secondary post option Miles Plumlee added a +9 thanks to a perfect shooting night from the field which yielded six points and three rebounds in just 17 minutes.

Kelly's backup, Josh Hairston, helped his cause to earn more minutes by posting the highest per minute rating with a +7 in just 13 minutes played. Hairston didn't miss from the field (3-of-3) and hauled in a rebound against the Buckeyes.

Notes: Mason Plumlee continues to separate himself from the pack as Duke's most efficient statistical player. The 6'10 junior now leads the team in both efficiency points and points per minute played - an impressive feat as he's played just six fewer minutes than team leader Seth Curry. Speaking of Curry, the junior combo guard dropped into fifth place in the points per minute category after playing 26 minutes against the Buckeyes. Austin Rivers upped his per minute rating and moved closer to triple digit points on the season. Rivers is also the team's leading scorer after eight games, averaging just over 15 points per contest. A few more rebounds and assists per game (possible if he sees more time handling the ball) and Rivers could very well challenge for a top three spot as the season moves along.
