Efficiency Ratings: Utah

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:

Kyle Kuzma scored 21 points to lead Utah to a 77-75, overtime win over No. 7 Duke in the Ameritas Insurance Classic on Saturday. Jakob Poeltl had 19 points and 14 rebounds before fouling out with 31 seconds left in overtime for Utah (9-2).

Duke's Luke Kennard led all scorers with 24 points. But the Blue Devils lost for the second time this season, falling to 9-2.

Utah led 73-67 after Jordan Loveridge made four free throws in a 10-second span, but Kennard brought Duke back, scoring eight points in 16 seconds to cut Utah's lead to 77-75.

Following a turnover by Dakarai Tucker, Duke had a chance to tie, but Brandon Ingram missed a layup and Kuzma grabbed the rebound.


vs.UTAH

(change from previous game)

  • Grayson Allen -4 (-25)
  • Matt Jones +12 (-13)
  • Brandon Ingram +14 (-24)
  • Amile Jefferson +DNP (-)
  • Marshall Plumlee +11 (-)
  • Luke Kennard +28 (+21)
  • Derryck Thornton +2 (-14)
  • Chase Jeter -3 (-8)
  • Antonio Vrankovic DNP (—)
  • Sean Obi DNP (-)


Notes: Luke Kennard had a very good afternoon in the Garden, scoring a career high in efficiency thanks to a 12-of-13 performance from the charity stripe and a career high eight rebounds. Outside of the Ohio freshman, however, Duke had an awful afternoon. Leading scorer Grayson Allen, who has averaged an efficiency score of +22 per game, scored a -4. It’s the second time the sophomore’s performance has sunk that low this season. The other time being against Kentucky which was also a game Duke lost. Joining Allen on the wrong side of the efficiency was Chase Jeter who posted a career low -3. So what was the major culprit for Duke? It starts with the missed field goals. Every starter missed at least 10 shots outside of Plumlee (who took just one). Other than the missed shots, the team played relatively well. Not many turnovers or other negatives.

SEASON HIGH/LOW PERFORMANCES


Tracking the most and least efficient performances by player

  • Grayson Allen 38/-4
  • Amile Jefferson 26/21
  • Brandon Ingram 38/-2
  • Matt Jones 25/10
  • Marshall Plumlee 23/12
  • Luke Kennard 28/0
  • Chase Jeter 12/-3
  • Antonio Vrankovic 8/1
  • Derryck Thornton 16/2
  • Sean Obi 0/0


Notes:

- Kennard’s big afternoon jumped up way up in both the cumulative and the per minute scores. His per minute numbers jumped all the way to .445, hopping over Jeter and Jones. - The least efficient player per minute for the Blue Devils is point guard Derryck Thornton. His season assist to turnover ratio isn’t bad for a freshman, but his field goal percentage and high number of missed field goals is pulling his score down as are his relatively high minutes.
