Efficiency Ratings: Virginia 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

Latest Game:

Jahlil Okafor scored a career-best 30 points, including four in overtime, and Quinn Cook scored 21 of his 26 in the second half and overtime Wednesday night as No. 4 Duke survived at Virginia Tech 91-86, the Blue Devils' eighth straight victory.

Okafor also grabbed nine rebounds and showed no ill effects of the sprained left ankle that caused him to miss the Blue Devils' previous game. Justise Winslow added 15 points for Duke (25-3, 12-3 Atlantic Coast Conference).

Jalen Hudson scored a career-high 23 points for Virginia Tech (10-18, 2-13) but missed a layup in the final seconds of regulation that could have given the Hokies their first victory against a ranked team in more than two years.

The performance came after coach Buzz Williams used Hudson for just one offensive possession in the Hokies' loss at North Carolina State last Saturday and for just nine minutes in the game before that.


vs. VIRGINIA TECH

(change from previous game)
  • Jahlil Okafor +30 (+30)
  • Justise Winslow +18 (-10)
  • Tyus Jones +9 (-7)
  • Quinn Cook +24 (-3)
  • Amile Jefferson +8 (+9)
  • Grayson Allen +2 (-8)
  • Matt Jones +13 (+7)
  • Marshall Plumlee +1 (-4)



Notes: Okafor had a monster game, his fifth time cresting the +30 efficiency mark on the season, and it could have been even better but for his old nemesis…free throws. Okafor hit just 4-of-9 from the charity stripe which held the big man’s score lower that it would have been AND had him on the bench during crucial portions of crunch time.

Duke got a big help from Amile Jefferson in limited action, while Cook and Winslow put together big games.

Meanwhile, Tyus Jones’ +9 was due in large part to 30 percent shooting from the floor and a lack of free throws (0-for-0).

Notes:

- Cook’s big game and Jones’ somewhat middle of the road performance results in Cook jumping Jones into second place. Meanwhile, Winslow has created quite a bit of separation from Jefferson in the season standings while also taking the junior’s starting spot against the Hokies.
