Efficiency Ratings: Georgia State

Using an NBA Efficiency Rating Formula, TDD tracks the best statistical performances of the season

As the Blue Devils progress through the season there will be many different theories on how to measure team success. TDD has adopted the 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 NBA 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.

The 2012-2013 season got off to a bit of a roller coaster start with Duke struggling to adapt to Georgia State's ever changing defense and some interesting match ups. Still, behind the consistency of seniors Mason Plumlee and Seth Curry, the Blue Devils pulled away from the Panthers with a run that straddled the halftime break and turned a two point game into a comfortable working magin.

(change from previous game)

Notes: Mason Plumlee was easily the best and most efficient player on the court for Duke. Given the makeup of the roster, and the focus of the Duke game plan, the second Plumlee is poised to win this seasonal competition by a landslide. The real drama may be reduced to whether or not he can beat his previous career high efficiency numbers (which are also the highest since TDD starting tracking efficiency scores) of +36 (Nolan Smith also had a +36 during his senior, ACC Player of the Year, season. Another note was the performance of the two point guards who recorded +16 and +15 scores despite the position being a note of concern for many fans. Both Thornton and Cook recorded career high efficiency scores.

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

Tracking the most and least efficient performances by player

  • Mason Plumlee: 29/--
  • Quinn Cook: 16/--
  • Tyler Thornton: 15/--
  • Rasheed Sulaimon: 10/--
  • Ryan Kelly: 10/--
  • Seth Curry: 8/--
  • Amile Jefferson: 7/--
  • Alex Murphy: DNP
  • Marshall Plumlee: DNP
  • Josh Hairston: -1/--

Notes: Mason Plumleee is the safest best to score both the highest cumulative and highest per minute scores for the second straight season. There are a number of interesting developments to track as the sample size continues to expand. Will Ryan Kelly become the second most efficient player again? How will the guard rotation shake out? How much Will Jefferson and Murphy factor in? Can Thornton keep putting up highly efficient games? Will Cook?
