Efficiency Ratings: Buffalo

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:

Duke pulled away to beat Buffalo 82-59 on Saturday behind 23 points from freshman Brandon Ingram.

Grayson Allen finished with 22 points and a career-best 11 rebounds, all on the defensive end, while Amile Jefferson had 13 points for the Blue Devils (8-1).

They won their sixth straight despite some offensive struggles: Duke never trailed but shot a season-worst 40.7 percent and matched a season low with five 3-pointers.

"We looked tired offensively in the first half. We were just chaotic," coach Mike Krzyzewski said. "We looked tired, Brandon gave us a big lift ... and they worked themselves through it."

This was Duke's ninth game in a 23-day span, and its third game of the week.


vs.BUFFALO

(change from previous game)

  • Grayson Allen +21 (+1)
  • Matt Jones +5 (-15)
  • Brandon Ingram +25 (-1)
  • Amile Jefferson +20 (-5)
  • Marshall Plumlee +4 (-2)
  • Luke Kennard +4 (-3)
  • Derryck Thornton +13 (-3)
  • Chase Jeter -2 (-2)
  • Antonio Vrankovic DNP (—)
  • Sean Obi DNP (—)


Notes: Allen and Ingram were terrific once again, scoring a combined +46. Allen’s score is particularly interesting in that he shot just 33 percent from the field and missed 10 shots in doing so. However, he countered those 10 missed shots with 11 rebounds (a career best) and by hitting 11 of 13 from the charity stripe.

The third top option, Amile Jefferson, was his usually efficient self, scoring a +20 despite shooting just six times on the night. The senior made five of those six attempts and added eight rebounds and 75 percent shooting from the free throw line.

On the flip side, Matt Jones struggled from the field (missing six of eight shots) to finish with just a +5 after posting a +20 against Indiana.
