Efficiency Ratings: Georgia Tech

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

Quinn Cook scored all 17 of his points in the second half, and Duke beat Georgia Tech 72-66 on Wednesday night to give Krzyzewski his Atlantic Coast Conference-record 423rd league victory.

Justise Winslow added 15 points and fellow freshman Jahlil Okafor had 14 for the Blue Devils (19-3, 6-3), who played for the first time since their win over previously unbeaten Virginia.

In the second half, Duke never trailed but also never led by more than seven points before finding a way to give their Hall of Fame coach a second milestone in 11 days.

Krzyzewski, who earned his 1,000th career victory Jan. 25 at St. John's, surpassed former North Carolina coach Dean Smith as the winningest in ACC play. He improved to 423-169 in his 35th year in the league.

Chris Bolden scored 16 points and Marcus Georges-Hunt had 14 for the Yellow Jackets (10-12, 1-9). Eight of their ACC losses have come by single digits.

vs. GEORGIA TECH

(change from previous game)
  • Jahlil Okafor +11 (-7)
  • Justise Winslow +27 (+7)
  • Tyus Jones +7 (-11)
  • Quinn Cook +16 (+3)
  • Amile Jefferson +12 (+9)
  • Grayson Allen 0 (+2)
  • Matt Jones +11 (+1)
  • Marshall Plumlee +1 (+1)



Notes: The Yellow Jackets had no real answer for Winslow who scored well, rebounded, and generally factored into each column of the stat sheet by also adding three assists, two steals, and two blocks in addition 15 points and 10 rebounds. The only think that kept Winslow from his first +30 or above performance was…you guessed it, free throw shooting. The freshman wing was just four of seven.

Inside Duke saw Okafor produce the least efficient game of his career with a +11. The big center missed seven of his 12 field goal attempts and managed just 50 percent of his free throws. He was also turnover prone early on, committing three on the night.

Despite playing 10 fewer minutes, Amile Jefferson was more efficient than his starting front court mate, posting a +12.
