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

Who had the better game? Using the above referenced formula player B, who hit five of eight shots and committed two turnovers registered a +20 efficiency total while Player A who missed 17 shots and had four turnovers had just a +11 rating.

LATEST GAME

Quinn Cook scored nine of his 12 points after the Blue Devils fell behind late, helping them beat Wake Forest 73-65 on Wednesday night.

Justise Winslow scored a season-high 20 points and fellow freshman Jahlil Okafor added 12 points and 11 rebounds in their first Atlantic Coast Conference road game.

But Cook came through in the final 5 minutes for the Blue Devils (14-0, 2-0), who kept pace with No. 1 Kentucky and No. 3 Virginia as the last unbeaten teams in Division I.

Duke shot 44 percent and pulled away by scoring on eight straight possessions down the stretch to win its closest game all year. The Blue Devils had won each of their first 13 by double figures.

Rasheed Sulaimon added 10 points for the Blue Devils, who dropped four of their previous five ACC road openers and lost in their last visit to Winston-Salem in March.

vs. WAKE FOREST

(change from previous game)
  • Jahlil Okafor +13 (-19)
  • Justise Winslow +21 (-1)
  • Tyus Jones +12 (+10)
  • Quinn Cook +12 (+3)
  • Rasheed Sulaimon +10 (-2)
  • Amile Jefferson +3 (-4)
  • Grayson Allen -1 (+2)
  • Matt Jones +6 (-4)
  • Marshall Plumlee +4 (-9)



Notes: It wasn’t Winslow’s best game of the season, but it may have been his most important as the freshman from Houston carried the Blue Devils when adversity struck. The 6’6 wing shot 7-of-16 from the field, grabbed seven rebounds and scored a team high 20 points to pace Duke to the victory. It resulted in a +21 rating - one point less than his game against Boston College last week, though certainly Duke needed this performance much more than one than the Eagles.

In the post Okafor did well with a double-double, and he shot well from the floor (67 percent on 4-of-6 from the field), but his free throw percentage (again) was lackluster, hitting just 50 percent, and he committed a season high five turnovers which transformed what would have been another +20 or greater performance into a +13.
