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
The Blue Devils beat No. 13 Louisville 72-65 on Monday night behind 18 points and 10 rebounds from freshman Brandon Ingram.
Grayson Allen scored 19 points and Luke Kennard had 11 for the Blue Devils (18-6, 7-4 Atlantic Coast Conference), who let a 15-point lead slip away in the second half before hitting 10 of 12 free throws in the final 3:14 and beating a ranked opponent for the first time this season.
The key stretch came when Louisville had the ball down 66-62 with about 2½ minutes left. Raymond Spalding left a layup short off the iron, Duke's Marshall Plumlee grabbed the rebound and it was at least a two-possession game the rest of the way.
Ingram and Jones both made two free throws on the next two possessions before freshman Derryck Thornton hit a jumper in the lane with the shot clock winding down to make it 70-62 with 33 seconds left.

Notes: Ingram broke out of his two game shooting slump to hit five of nine from the floor and also led the team in rebounding to finish with a +24. Ingram also out-performed his season average at the free throw line by hitting 75 percent of his attempts from the charity stripe. The knock on Ingram’s stat line was the 3 posted in the turnover column. Still, for most of the night he was both the best and most impactful player on the court.
Both Marshall Plumlee and Grayson Allen also posted solid numbers. Plumlee’s +16 came on the strength of 80 percent from the free throw line and another solid line of 10 points and eight boards. Meanwhile, Allen appeared on pace for another huge score after posting 16 first half point, but cooled off considerable in the second half to finish with 19 points on 5-of-12 shooting. Still, he managed a game high +24.
