Efficiency Ratings: Kansas

As the Blue Devils progress through the season there will be many different theories on how to measure team success. TDD has adopted an 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 above referenced 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 Blue Devils struggled with their defense against a big and athletic Kansas team. Despite the brilliance of Jabari Parker, Duke eventually fell to the Jayhawks 94-83.

v. Kansas
(change from previous game)


Notes: The game against Kansas featured another big performance from Parker, but the super freshman didn't get a lot of help on the offensive end. Captain Rodney Hood struggled to remain aggressive, and managed just 11 points on 3-of-8 shooting. Similarly, Rasheed Sulaimon didn't find his offense until late in the second half while starter Quinn Cook had a poor performance as well. And while Amile Jefferson scored in bunches and was efficient doing it (7-of-9 from the field), the sophomore forward managed just two rebounds in 26 minutes.

Rebounding as a whole was an issue for Duke, but primarily in the ground of players charged with manning the post. Aside from Parker's game high nine boards, Duke's trio of Jefferson, Josh Hairston, and Marshall Plumlee - the group expected to man the five this year - managed two rebounds in 38 combined minutes.

Only Parker and Jefferson put up better games from the opener against Davidson. The team as a whole struggled mightily on the boards and at the free thrown line (16-of-28). The Blue Devils also utilized a much shorter bench, with Alex Murphy and Semi Ojeleye unable to log any minutes.

SEASON HIGH/LOW PERFORMANCES
Tracking the most and least efficient performances by player

  • Rodney Hood +30/+6
  • Jabari Parker +29/+27
  • Amile Jefferson +14/+7
  • Quinn Cook +29/+10
  • Rasheed Sulaimon +25/+8
  • Tyler Thornton +10/+8
  • Matt Jones +5/-3
  • Alex Murphy +6/-1
  • Josh Hairston +1/+0
  • Semi Ojeleye -1/-
  • Andre Dawkins +0/-
  • Marshall Plumlee +1/-


Notes: Rodney Hood's disappearing act on the offensive end put extraordinary pressure on the offense which was compounded by poor team free throw shooting and four players spending long periods watching Parker operate. As Duke prepares for the Preseason NIT and a potential matchup with Arizona in the final, the Blue Devils will need to get more rebounding and defense from the post, more consistency from Hood, Cook, and Sulaimon, and a lot better shooting from the charity stripe.
