Efficiency Ratings: Wake Forest

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.

Duke used a balanced scoring attack to pull away from Wake Forest on Saturday afternoon in Cameron Indoor Stadium in the ACC opener for both teams. The Blue Devils (14-0, 1-0) shot 46 percent in their Atlantic Coast Conference opener and hit 11 3-pointers — including six during the 25-7 first-half run that put them up big.

Kelly, who entered averaging 21 points in the previous three meetings in the series, will get another crack at the Demon Deacons when the Blue Devils visit Winston-Salem on Jan. 30.

He had 17 points at halftime of this one, including 13 of Duke's first 19, with three 3s — including two some 45 seconds apart — during the Blue Devils' first big run. His 3-pointer 2½ minutes into the second half pushed him past the 20-point mark for the fifth time in his career.

(change from previous game)

Notes: Were it not for a horrendous shooting performance (0-11), Quinn Cook would have posted another big game after dishing 14 assists against just one turnover. Instead, the sophomore point guard actually posted his lowest efficiency score of the season with a +6. Despite being double and triple teams throughout much of the game, Mason Plumlee managed to post another double-double (13 points, 12 rebounds) to post a +18 after recording his season low efficiency score against Davidson earlier this week. Ryan Kelly posted a third straight game with a +19 or higher.

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