Efficiency Ratings: Temple

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.

Perhaps the memory of last year's upset was fresh in the Blue Devils' mind, and the team wanted to make a statement that Temple's three point victory over then No. 3 Duke was a bit of a fluke. Whatever the reason, Duke's 23 point victory over the previously unbeaten Owls was due to a combination of efficiency, hustle, and talent. After falling behind 4-0 early, Duke methodically built a double-figure lead and was never challenged afterwards. Both Plumlee and Kelly registered double-doubles despite some trouble finishing around the rim for both. In the backcourt, it was another shooting display from Curry while Cook ran the team efficiently. All told, Duke put four starters into double figures, with the fifth starter logging eight points and seven assists.

(change from previous game)

Notes: As noted above, both Plumlee and Kelly missed a number of attempts around the basket, which would have not only pushed the team's margin of victory to close to 30, but would have also pushed each player's efficiency rating well above 20. The reason for the bump would have been a combination of points and improved shooting percentage (Plumlee finished 5-of-14, while Kelly hit just three of nine) Curry's +21 was almost solely a result of his shooting performance (7-of-11 from the field and perfect at the free throw line), as he register just three assists and one turnover along with no rebounds. Though his scoring was off, Rasheed Sulaimon over came a 2-of-6 for 8 points night by dishing out seven assists against no turnovers.

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: 34/17
  • Quinn Cook: 19/7
  • Tyler Thornton: 16/1
  • Rasheed Sulaimon: 16/9
  • Ryan Kelly: 20/10

Notes: Murphy's playing time over the last two games have helped him move up the charts with a combined +16 against Delaware and Temple. Similarly, Amile Jefferson has overtaken Josh Hairston in the season, per game, and per minute scores. On the efficiency per minute numbers, it's interesting that Rasheed Sulaimon has the lowest score per minute of the rotational players.
