Efficiency Ratings: Maryland

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.

Parker scored 23 points and blocked one of Maryland's two shots in the final 10 seconds of the Blue Devils' 69-67 victory Saturday night.

"That was vintage Cameron, man," Duke coach Mike Krzyzewski said. "That was one for the ages."

Rodney Hood and Rasheed Sulaimon added 11 points each for the Blue Devils (20-5, 9-3 Atlantic Coast Conference), who won their eighth in nine games and started a run of four games in eight nights by giving the Terrapins a hard-to-swallow loss in their last scheduled visit to Cameron Indoor Stadium.

The ACC's top 3-point shooting team was just 5 of 24 from long range and shot 23 percent in the second half. Duke led by double figures for all of about 15 seconds before scratching its way to the 20-win mark for the 18th straight year.

v. Maryland
(change from previous game)

Notes: With Rodney Hood out for nearly half the game with foul trouble, Duke once again got a life from Parker and Jefferson. The freshman forward recorded another "zero-zero" by recording at least one of every statistical category. Such versatility overcame a rather pedestrian 6-of-16 shooting performance to leave Parker with a +22.

Jefferson, meanwhile, recorded his high score of +18 by hauling in 12 rebounds to compliment his seven points (on 3-of-5 shooting), one block and one steal.

No other Blue Devil hit double figures in efficiency scoring on a night where Duke shot the ball extremely poorly from the perimeter and from the field overall (just 33 percent). The third best performance of the night was from Sulaimon whose +7 came despite the sophomore shooting just three of nine fro, the field to finish with 11 points.

Perhaps the biggest area of concern for Duke is at the lead guard position where junior Quinn Cook continues to struggle. Against Maryland, Cook earned just 14 minutes overall and recorded a +3. His shot wasn't falling (1-of-4), but the real concern was the 0-to-3 assist to turnover ratio.

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 +37/-1
  • Amile Jefferson +28/+1
  • Quinn Cook +31/+2
  • Rasheed Sulaimon +25/-2
  • Tyler Thornton +15/+0
  • Matt Jones +12/-3
  • Josh Hairston +8/-1
  • Semi Ojeleye +16/-1
  • Andre Dawkins +23/-3
  • Marshall Plumlee +10/-1

Notes: Plumlee's performance in just six minutes of action against Maryland not only helped Duke in a big way (drawing fouls, put back basket, and bothering shots), it also moved the sophomore big man past Tyler Thornton in the per minute statistics on the season. In the cumulative totals, Jabari Parker has opened more than a 100 point lead on Hood, while Jefferson is within six points of Quinn Cook for third place.
