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
Grayson Allen scored 30 points in Duke's 79-71 victory over Wake Forest on Tuesday night.
Marshall Plumlee added 13 points and matched a career high with 17 rebounds, and freshman Brandon Ingram finished with 15 points and 11 rebounds for the Blue Devils (22-8, 11-6).
They overcame some cold early shooting and shot 46 percent in the second half to earn their 17th straight home victory over Wake Forest.
Devin Thomas had 16 points and 13 rebounds and freshman Bryant Crawford scored 15 points for the Demon Deacons (11-19, 2-16). Codi Miller-McIntyre added 13 points, and his layup with 38.6 seconds left pulled them to 76-70.

Notes: Allen and Plumlee were the stars of the night, with Allen scoring in bunches and Plumlee recording a career high 17 rebounds. With Plumlee the senior big man posted a +21 which would have been higher were it not for an uncharacteristically poor shooting night. Plumlee shot less than 50 percent from the field (4-of-9) and free throw line (5-of-11).
Meanwhile, Allen scored 30 points on 7-of-16 shooting from the field, but his score took a bit of a dive with five missed free throws.
