Efficiency Ratings: Santa Clara

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

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.


LATEST GAME
The time off for the holidays, plus a very game opponent resulted in a tightly contested game for the first 30 minutes against Santa Clara. After exchanging leads and runs throughout the game, Duke finally wore down their opponent and pulled away to win by 13. It was a career day for Curry who scored 31 points on 67 percent shooting from the field.

v. Santa Clara
(change from previous game)


Notes: The three seniors were the difference, as each scored +19 or higher. Curry's high point out-put and good shooting numbers resulted in tying his career best efficiency score (against Minnesota earlier this year), though it wasn't good enough to out-pace Mason Plumlee who added 22 points, 13 rebounds, and 5 assists. Ryan Kelly added a double-double as well with 10 points and 11 rebounds. Quinn Cook's late scoring barrage was enough to push his score up to +17 thanks to 15 points, five rebounds, and five assists (against just two turnovers). Despite his score of just +1, Tyler Thornton's defense and disruptive play against Santa Clara proved to be a big help as Duke weathered run after run.

Notes: The highest individual game scores are easy to predict these days as the top 10 games have all be turned in by Curry and Plumlee. Similarly, Plumlee is averaging the highest season efficiency score in the four years TDD has been keeping track. And he's doing it by nearly four full points while playing heavy minutes. Lost in how well Plumlee has been playing has been the consistency of both Ryan Kelly and Quinn Cook. After the preseason in which Cook had a horrendous assist to turnover ratio, the sophomore point guard has settled in and averaged a +15.0 rating on the season thanks to a +41 assist to turnover ration in 12 games. Meanwhile, Kelly hasn't been flashy, but he's turned in double-figure efficiency games in all 12 contests. When his shot isn't falling, Kelly is splitting time rebounding, blocking shots, coming up with steals, and hitting FTs to keep his score high.
