Efficiency Ratings: UNC-Asheville

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

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
Jabari Parker had 21 points and 10 rebounds in his fourth straight 20-point game, leading the sixth-ranked Blue Devils past UNC Asheville 91-55 on Monday night in the opening round of the NIT Season Tip-Off.

Duke held a 42-28 rebounding advantage, built a 20-point first-half lead and coasted to its 104th straight non-conference win at Cameron Indoor Stadium.

v. UNC Asheville
(change from previous game)


Notes: Parker would have posted a higher score but for his career high six turnovers - he had just three in the first three games. The Chicago freshman continually forced the ball to his teammates in an attempt to be unselfish…though Coach K would like to see more selfishness from his star.

"A really good player isn't concerned about his points, and he's looking for his teammates to maybe have a better night and give them some confidence," Krzyzewski said. "For a freshman to do that is very good. Look, he's exceptional. What he tried to do tonight was OK.

"I'd rather have him shoot it, to be quite frank with you."

Meanwhile, Rodney Hood continued his streak of aggressive play by scoring 15 of his 18 points in the first half.

Duke also got a shot in the arm on the boards from Semi Ojeleye who put together his best game in a Duke uniform. Playing both forward positions, the 6'7 Ojeleye scored 10 points and grabbed five rebounds in just 14 minutes. As a team, Duke won the battle of the boards 42-28.

SEASON HIGH/LOW PERFORMANCES
Tracking the most and least efficient performances by player

  • Rodney Hood +30/+6
  • Jabari Parker +29/+24
  • Amile Jefferson +14/+7
  • Quinn Cook +29/+8
  • Rasheed Sulaimon +25/+5

Notes: Ojeleye moves way up in the per minute and per game ratings with a +16 (1.143/minute) performance against UNC Asheville. The 6'7 forward is certainly making his case to assist the Blue Devils on the boards after the team identified a real deficit in the rebounding game through three games. Jabari Parker is the first player in program history to score 20 points or more in his first four games.
