Efficiency Ratings: Wake Forest

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:

Marshall Plumlee scored 14 of his career-best 18 points in the second half of the Blue Devils' 91-75 victory over Wake Forest on Wednesday night.

Grayson Allen scored 24 points, freshman Luke Kennard added 23, and Brandon Ingram had 17 for the Blue Devils (13-2, 2-0 Atlantic Coast Conference).

They shot 52 percent and overcame some serious foul trouble to their thin rotation to win their fourth straight and open an ACC season with consecutive road victories for just the second time under coach Mike Krzyzewski. Duke is down to seven players in the regular rotation with forward Amile Jefferson out indefinitely with a broken foot.


vs.WAKE FOREST

(change from previous game)

  • Grayson Allen +29 (+2)
  • Matt Jones +0 (-13)
  • Brandon Ingram +22 (-3)
  • Amile Jefferson +DNP (-)
  • Marshall Plumlee +28 (+23)
  • Luke Kennard +27 (+7)
  • Derryck Thornton +5 (+4)
  • Chase Jeter +0 (-)
  • Antonio Vrankovic DNP (-)
  • Sean Obi +0 (-)


Notes: Marshall Plumlee’s perfect night from the floor and the charity stripe resulted in the best game of the senior’s career. Not only did he score (18) and rebound (7) well, Plumlee also played mistake free with zero turnovers and added a pair of blocks as well. His +28 was five points higher than his previous career high of +23 against Kentucky and is just the third time in his career he’s scored better than +20 in a game.

Off the bench Duke got a lift from Luke Kennard whose +27 was one off his career best thanks to a nice night shooting (7-of-11) and a perfect night from the free throw line (9-of-9). Kennard also rounded off his stat line with five rebounds and three assists (against just one turnover).

Much like Kennard, Grayson Allen’s score (+29) was boosted by a strong night at the foul line (7-of-8) and the sophomore added four rebounds and three assists to a game high 24 points.

Brandon Ingram’s +22 score was helped by the freshman’s all around game including five rebounds, three assists, four blocks, and three steals. He scored 17 points, and the all around floor game helped overcome eight misses in 13 field goal attempts.

Notes:

- Matt Jones had a very rough night from the floor after making his first shot. For the rest of the game the junior missed seven straight attempts and scored a +0. With so many other players accumulating stats, Jones dropped to fourth in the season ratings and is just eight points clear of Kennard who has moved up fast in recents games. Kennard and Plumlee both passed Jones in the per minute table as well.

- A little more than a week ago it appeared as though Brandon Ingram would be challenging Grayson Allen for the top spot in the cumulative scoring. Since that time the freshman has maintained better than a +20 pace, but Allen has actually extended his lead with a +28 average in his two ACC games.
