Efficiency Ratings: Game 18

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.

For reference, last year LeBron James posted the two most efficient games of the season with a +54 (37 points on 11-of-17 FG & 9-10 FT, 12 rebounds, 11 assist, 2 steals, 1 block, and 2 turnovers) and +50 (40 points on 16-of-23 FG & 6-6 FT, 8 rebounds, 8 assist, 1 steal, 2 blocks, and 2 turnovers) rating.

Just as the national media was beating the lack of post production from the Plumlee brothers and Kelly into the ground further, the trio of Duke bigs produced their best game of the season as Duke held off NC State 92-78 in Raleigh. Duke attacked the basket early and owned the glass on both ends of the floor. Despite a very slow start, Singler responded late with a handful of big baskets to keep the Wolfpack rally at bay.

Notes: The post presence of Kelly and the Plumlees was the best of the year with the three players combining for 57 rating points between them - 19 each. After a strong start, Andre Dawkins was saddled with foul trouble as was Seth Curry. It resulted in the two players combining for just eight points. Kyle Singler and Nolan Smith were their predictable selves when it came to production. Singler struggled from the field (6-of-18), but rebounded from a slow start to carry Duke late while also grabbing nine rebounds. Off the bench it was Tyler Thornton providing a spark when Curry and Dawkins were saddled with foul trouble, posting a +9 rating.

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

Notes: In the presume story we noted that Duke needed to get more help from the bench. On Wednesday night the Blue Devils got season high efficiency ratings from three players - Miles Plumlee, Ryan Kelly, and Tyler Thornton. The elder Plumlee tied his season high with 19 points - previously hit against Bradley. Thornton upped his season high of seven E-points while Kelly added two points to his season high of 17. On the season's efficiency rating Miles Plumlee moved past Seth Curry into seventh place while Ryan Kelly passed Kyrie Irving for fifth place. Irving also fell behind Smith in the E/game table.
