Efficiency Ratings: Maryland

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.

A third game in six days mixed with a supremely motivated opponent ended up being too much for the Blue Devils on Saturday evening in College Park. Maryland hung around throughout the first half before taking the lead into intermission. From there the Blue Devils fell behind by as many as 10 before rallying to somehow have a chance to win at the buzzer. However, Cook's 40 footer missed by inches and Duke fell for the third time this year.

v. Maryland
(change from previous game)

Notes: That Duke was able to have a chance to win the game despite getting virtually nothing from Mason Plumlee is amazing in and of itself. The senior, who is averaging more than a +23 per contest, recorded the lowest score of his four year career on Saturday with a +0. Plumlee's score was a result of a poor field goal percentage (2-of-7), and low rebound and point totals (3 boards and four points). Plumlee also turned it over twice and fouled out.

With Kelly still on the sidelines, the once senior lead Blue Devils got contributions from just 1/3 of their senior class. Seth Curry kept Duke in the game with 14 first half points, and recorded another +20 or higher score. Curry recorded just one rebound, but was helped by shooting 11-of-17 from the floor and handing out three assists, and picking up two steals.

The rest of the backcourt rotation picked their games up at various times as well. Sulaimon responded to a dull first half by scoring 16 points after halftime to finish with a +14. His score was dinged by a field goal percentage of 33.3%. Meanwhile, Cook also added a +14 thanks to scoring (18 points) and assists (6), and steals (4). Where the sophomore point guard saw a drop in scoring was a continuing bout of turnovers (five more) and a lower shooting percentage (6-of-16).

Off the bench, Duke got a life from Tyler Thornton who recorded a +11 despite scoring just three points on one shot attempt. Thornton's score was pushed up by four steals, no turnovers, and two each in the rebounds and assists column.

Perhaps the MVP for Duke on this night (aside from Curry) was Josh Hairston. The junior forward hit four of five shots, rebounded well enough (3), and scored 11 points to finish with a season high +12.

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