((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.
On an incredibly emotional night two players who can each make a strong case for having their numbers immortalized in the rafters overcame the magnitude of their final games to help Duke defeat Clemson by 11. The Tigers fell behind by 11 in the first half, but used a 14-5 run to close the first half and trailed by just two heading into the locker room. However, the Blue Devils saw two secondary options emerge in the second half in the form of Curry and Plumlee both on the boards and in the offensive flow to keep Clemson at bay. The end result was a second consecutive season of not losing at home.

Notes: The formula used measures offensive performance. In the final home game of the season, Nolan Smith's statline looks very impressive. The senior scored 21 points, grabbed four rebounds, and handed out seven assists. However, Smith's efficiency rating was just a +9. Why? The shooting percentage (7-20 for 35 percent) didn't help, but the true killer was the assist to turnover ratio of 7 assists against a season high 8 turnovers for Smith. Had the senior maintained his 1.8/1 ratio and logged seven assists, he would have a full +5 improvement on his efficiency rating for this game. A similarly interesting look is Mason Plumlee's line. The sophomore big man scored eight points (including 4/5 FTs) and grabbed seven rebounds. The biggest boost came in the form of five blocks, two assists, and shooting percentages as Plumlee posted a +18 rating. In his final night in Cameron, Singler posted not only an efficient performance, but also a standard one. Sure the field goal percentage wasn't as high as he's capable (5/12), but Singler found ways to get points (18) and managed to grab a game high 11 rebounds. He also managed to record a block, a steal, and a couple of assists while committing turnovers. When he wasn't terrorizing the Clemson defense with hustle plays and skill, he was making a number of key defensive plays including a huge block that'll be on the top 10 plays of the game and a falling out of bounds deflection off the Clemson defender.

Notes: As the home game portion of the season is concluded, the Blue Devils have clearly defined roles heading into March. The efficiency ratings match up with both the Duke rotation and playing patterns. Nolan Smith and Kyle Singler are the headliners, but sophomore post man Mason Plumlee is actually closer to Singler's efficiency rating than to fourth place Ryan Kelly. Meanwhile, the most recent and final addition to the usual starting lineup, Seth Curry, has finished as the fifth most efficient offensive performer.
