Efficiency Ratings: Bryant

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:
Grayson Allen scored a career high 28 points while junior captain Matt Jones added a career best 19 as Duke rolled past Bryant 113-75 on Saturday night in Cameron Indoor Stadium.

In all there were five Blue Devils who scored in double figures with freshman Brandon Ingram scoring a career best 21 points while Amile Jefferson and Luke Kennard added 11 points apiece for Duke. Jefferson added 11 rebounds as well to mark his second consecutive double-double.

On Friday Duke struggled from the perimeter against Siena for most of the game, but it was a different story on Saturday as the Blue Devils knocked down 13 of 26 attempts from long range. Defensively the hosts forced Bryant into 19 turnovers which accounted for 24 points.

Duke never trailed and led by as many as 40 before settling for the 38 point victory.


vs.BRYANT
(change from previous game)

  • Grayson Allen +26 (-2)
  • Matt Jones +21 (+11)
  • Brandon Ingram +23 (+12)
  • Amile Jefferson +21 (-5)
  • Marshall Plumlee +12 (-2)
  • Luke Kennard +15 (+8)
  • Derryck Thornton +6 (+4)
  • Chase Jeter +12 (+9)
  • Antonio Vrankovic +8 (+7)
  • Sean Obi DNP (—)

Notes: For the second straight game the Blue Devils were able to impose their will against a clearly overmatched opponent. Both Matt Jones and Grayson Allen had stretches where each player took control of the game and each posted strong numbers with Allen once again topping the +25 mark.

Duke also got a lift from Brandon Ingram who began to knock down shots from the outside and finished the night shooting 7–of-11 from the field to post a season/career high +23. Ingram’s rebound and assist numbers are still somewhat low, but those will likely pick up once the rotation settles in.

In just four minutes, freshman center Antonio Vrankovic posted a +8 thanks to making both field goals and pulling in three rebounds.

Notes:
- Allen and Jefferson have jumped out to early leads in both season categories with the sophomore scoring guard putting up huge point totals and Jefferson countering with a pair of double-doubles in his first two contests. 

- Though it’s early, Duke has shown a great deal of balance in all statistical categories with numbers being distributed fairly evenly amongst the top seven players. Six players are averaging double figure efficiency points compared to just five a season ago.
