Efficiency Ratings: Ohio State

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
Playing a fourth game in seven days is tough enough. Playing a second top five opponent makes it worse. And yet, Duke found a way to beat No. 4 Ohio State by five on Wednesday night as part of the ACC/Big 10 Challenge. It began in the middle where Mason Plumlee scored 21 points to go along with 17 rebounds in 39 minutes of action. The effort continued on the perimeter where freshman Rasheed Sulaimon rebounded from scoreless first half to score 17 points after intermission in helping Duke erase a double-digit deficit. The Blue Devils finished the early season gauntlet with a perfect 7-0 record and have beaten the number two, three, four, and 21st ranked teams in the country.

v. Ohio State
(change from previous game)


Notes: Curry's nagging leg injury and an episode that saw him roll his ankle early in the second half limited the senior to his worst output of the year. Curry hit only one of his six shot attempts to finish with a season low four points, which brought his score down. There was no such efficiency drop for Plumlee, however, who logged the season's third highest total (+31) thanks to 21 points and 17 rebounds. It's the third time the potential all-American has topped 30 efficiency points this season. Sulaimon's +14 was spurred on by efficient shooting (7-of-12), but could have been higher had he registered anything in the steals, assist, and/or blocks column.

Notes: The race for most efficient player has long since been won by Mason Plumlee. Barring injury, the senior will likely lap the field - perhaps more than once. Plumlee has already posted three of the most efficient performances in the history of these ratings (three year period), and we're just seven games into the season. On the year, Mason is averaging nearly a +27 which would be four points higher than the highest score ever (Nolan Smith's senior, ACC Player of the Year season). Curry's off-night allowed both Quinn Cook and Rasheed Sulaimon to pass him in the cumulative scores, which Cook also jumping the senior in the per minute scoring.
