Efficiency Ratings: Wake Forest

Using an NBA Efficiency Rating Formula, TDD tracks the best statistical performances of 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 season-best 27 points, and Duke routed Wake Forest 94-51 on Wednesday night for its 10th straight win.

Matt Jones added 17 points for the Blue Devils (27-3, 14-3), who shot 58 percent and forced 19 turnovers in locking up the No. 2 seed in next week's Atlantic Coast Conference tournament.

Duke had a double-figure lead before the Demon Deacons managed their first basket, scoring the first 12 points and rolling to their 16th straight home victory in the ACC's oldest series.

Codi Miller-McIntyre scored 20 points for Wake Forest (13-17, 5-12), which has lost four of five.

Quinn Cook had 13 points in his Cameron Indoor Stadium farewell and Justise Winslow also had 13.

Jahlil Okafor finished with six -- his first single-digit scoring game -- after some early foul trouble.


vs. WAKE FOREST

(change from previous game)
  • Jahlil Okafor +7 (-14)
  • Justise Winslow +27 (-2)
  • Tyus Jones +15 (+1)
  • Quinn Cook +10 (-2)
  • Amile Jefferson +14 (+11)
  • Grayson Allen +28 (+27)
  • Matt Jones +16 (+7)
  • Marshall Plumlee +9 (+8)



Notes: Allen’s scoring outburst resulted in a not only a career high in points, but also a season best in these ratings. Worth noting was Allen’s +28 score was due almost entirely to his shooting and rebounding. He recorded no assists, turnovers, steals, or blocks, but hitting nine of 11 field goals and five of six from the foul line was enough to keep his score high as the formula rewards good shooting, not volume.

Similarly, Justise Winslow may have been slowed by injury, but he still managed a +27 thanks to an all around game which included 13 points (6-of-8 FG), six rebounds, seven assists, and six steals. It’s the closest anyone has come to a quadruple double this season and pulled his score past +25 for the third time in the last four games.

In the middle there wasn’t much need for a brilliant performance from Okafor, and early foul trouble limited the big man to just six points and four rebounds in 19 minutes. Okafor’s freshman scoring record of double figure games was snapped and this was his only game without at least a +10 in the ratings. What kept him from making a +10? Three turnovers against just one assist.
