Efficiency Ratings: Boston College

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.

After the Eagles were successful in slowing down the Blue Devils on their home floor, Duke made sure to jump on Boston College early in the Sunday rematch at Cameron Indoor Stadium. Duke got early contributions from Plumlee and Curry before the freshman duo of Jefferson and Sulaimon took over to the tune of 25 first half points. The Eagles would never get closer than 23 the rest of the way as Duke improves to 24-3 on the season and 11-3 in the ACC.

(change from previous game)

Notes: Plumlee continues to dominate the stat sheet with a 17th double-double on the season. The senior big man shot over 50 percents, pulled in 15 rebounds, and would have eclipsed the 30 efficiency point mark were it not for four turnovers, two on offensive fouls.

Meanwhile, Sulaimon was "sensational" according to head coach Mike Krzyzewski. The freshman hit 10 of 15 shots, scored 27 points, and added three assists and rebounds. It was the best performance of the Texan's young career.

Similarly, Amile Jefferson was extremely effective in scoring after and through contact, earning three different "and-1" conversions throughout the night. In the "wouldn't believe it" category, Jefferson managed to record just one rebound in 21 minutes of action.

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