Efficiency Ratings: Georgia Southern

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

Latest Game:

Brandon Ingram had season highs of 26 points and 14 rebounds, leading Duke to a 99-65 victory over Georgia Southern.

Grayson Allen added 18 points, Matt Jones had 16 and Derryck Thornton finished with 15 for the Blue Devils (9-1) in their first game without high-energy forward Amile Jefferson.

Playing for the first time in 10 days due to final exams, Duke wasn't always crisp but still had little trouble pulling away for its seventh straight win. The Blue Devils shot 57.6 percent in the second half and held a 55-29 rebounding advantage.

Notes: The loss of Jefferson opens around 34 minutes per game in the rotation. Against Georgia Southern those minutes were evenly distributed among freshmen Chase Jeter, Luke Kennard, and Derryck Thornton. Of that group, Thornton had the most efficient nice, posting a +16. Kennard played the most minutes and contributed with rebounding and free throws more than shooting (4-of-14 from the field). Meanwhile, Jeter got some late positive plays to build some confidence. As for their classmate, well…Brandon Ingram was quite good. In fact, he posted a monster stat line of 26 point, 14 rebounds, two assists, and two blocks. It resulted in a +38, which tied Grayson Allen for the best performance of the year.

Notes:

- Ingram’s big game moved him up the season cumulative and the per minute ratings. Given Ingram’s expanding role, it will be interesting to see whether or not he can catch Allen in the cumulative scoring. Currently there’s a gap of 72 points between the players.

- Matt Jones jumped over Plumlee, and Derryck Thornton passed Kennard.
