Efficiency Ratings: Boston College

Rasheed Sulaimon

Using an NBA Efficiency Rating Formula, TDD tracks the best statistical performances of 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 above referenced 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.


LATEST GAME
BOSTON (AP) — Jabari Parker set career highs with 29 points and 16 rebounds, Quinn Cook hit five 3-pointers and scored 21 points, and No. 11 Duke coasted to an 89-68 win over Boston College on Saturday night.

Rasheed Sulaimon added 10 points for the Blue Devils (19-5, 8-3 Atlantic Coast Conference). Parker extended his Duke freshman record to 14 games with 20 points or more.

Olivier Hanlan led Boston College (6-17, 2-8) with 25 points and Ryan Anderson had 12. The Eagles have dropped 10 of 12, with their only conference wins coming against last-place Virginia Tech.

The Blue Devils put it away with an 18-0 run midway through the second half, improving to 18-2 against unranked teams this season.


v. Boston College
(change from previous game)


Notes: Parker's +37 was notable on a number of fronts. It was his career best, the best of the season, and the second highest performance we've tracked since starting these efficiency ratings several years ago. The best performance was Mason Plumlee's +39 against Marquette. Jabari could have eclipsed the +40 mark had it not been for subpar free throw shooting (5-of-10), which was the only knock on an otherwise flawless performance.

The big question surrounding Duke for the last few weeks has been the play of Quinn Cook. Is the junior PG back? It's still too early to tell, but a stellar shooting night certainly seemed to suggest the former starter was heading in the right direction.

At point guard, Rasheed Sulaimon and Tyler Thornton both started and both scored in double figures. The duo combined for 12 assists against just one turnover. Sulaimon's score took a hit as the sophomore shot just 2-of-8 from the field.

In the post, Amile Jefferson had a very quiet +16 thanks to a perfect night shooting the ball (3-3 FG, 2-2 FT) to finish with eight points and six rebounds in 29 minutes. Rather than Hairston or Plumlee (injury), Coach Mike Krzyzewski went with rarely used Semi Ojeleye for the majority of the backup minutes. The Kansas product produced no efficiency points in eight minutes despite averaging +0.574/minute heading into the game.
