Efficiency Ratings: Gardner-Webb

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.

Freshman Jabari Parker scored 21 points to help No. 8 Duke beat Gardner-Webb 85-66 on Monday night in its first game in nearly two weeks.

Andre Dawkins added a season-high 18 points for the Blue Devils (8-2), who hadn't played since beating Michigan on Dec. 3 in the Big Ten/ACC Challenge.

That break, which included final exams, came after a tough stretch of four games in 10 days that included a loss to top-ranked Arizona in the NIT Season Tip-Off championship and a one-point home win over Vermont just before Thanksgiving.

"You don't stop playing for two weeks and not have some slippage," Krzyzewski said. "But overall I was pleased with our team."

Duke won't have to wait nearly as long to get back on the court. The Blue Devils face UCLA on Thursday in New York in their last game before the Christmas holiday.

(change from previous game)

Notes: Andre Dawkins had a big shooting night, finishing with 18 points in just 22 minutes of action to post his season high in scoring. Meanwhile, Jabari Parker got back on track with his usual all-around game, scoring 21 points and grabbing six boards in just 26 minutes.

The post rotation still seems to cause debates amongst the fan base, and the reason is easy to see in ratings such as these (which don't consider stats and factors not appearing in the box score): Amile Jefferson played just 12 minutes and posted a +10 thanks to 10 rebounds in that time. The sophomore's score would have been much higher but for some missed free throws (an area where he's shooting a dismal 31 percent on the season), and his 40 percent shooting from the field. The other post options, Marshall Plumlee and Semi Ojeleye combined for 11 minutes, two points, three rebounds, and one block. Starter Josh Hairston logged a lion's share of the minutes (23) and posted four points, two rebounds, and a block for a +7 rating.

Point guard Quinn Cook mirrored his team's start with a blistering first half - one in which he handed out nine assists, but slowed after half-time without any further helpers handed out. He finished with a +23 thanks to 16 points, nine assists, and four rebounds. His score took a small hit thanks to four turnovers.

Throughout the season TDD will track the various highs and lows using the formula.

Tracking the most and least efficient performances by player

  • Rodney Hood +32/+3
  • Jabari Parker +30/+5
  • Amile Jefferson +16/+1
  • Quinn Cook +31/+8
  • Rasheed Sulaimon +25/-2
  • Tyler Thornton +15/+0
  • Matt Jones +12/-3
  • Josh Hairston +8/+0
  • Semi Ojeleye +16/-1
  • Andre Dawkins +19/-3
  • Marshall Plumlee +4/-1

Notes: Clearly the biggest drop off of the season has been the disappearance of former starting scoring guard Rasheed Sulaimon. The sophomore, who was on several NBA and post-season award watch lists, has earned just five minutes in the last two games and posted a combined efficiency score of -2. Meanwhile, Andre Dawkins' numbers continue to show the senior scorer as instant offense off the bench. In the season table, Quinn Cook is quietly closing the gap (which had been significant) on Rodney Hood for second place.
