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
No. 15 Duke had some extra time to keep figuring out how to play without its injured leader and big man. For one half, anyway, things couldn't have gone much better for the Blue Devils.
Duke scored 70 points in the first half of its 105-66 rout of Elon on Monday night
Freshman Brandon Ingram matched a season high with 26 points and added 11 rebounds while fellow freshman Luke Kennard had 18 points and Grayson Allen and Matt Jones had 17 apiece.
Scoring 70 in a half for just the third time in program history, the Blue Devils (10-2) shot 58 percent in the opening half and led by 30 points after just over 13 minutes. They reached 100 for the second time this season but fell seven points shy of a season high.

Notes: Against Utah the Blue Devils’ offense seemed broken. Fast forward to the Elon game and you saw a Duke team that was a virtual buzzsaw on that end of the court. Each of the top six players registered a +12 or higher rating with Ingram registering another score over 30.
The freshman’s rating was helped by hitting 11 of 16 shots, scoring a game high 26 points and grabbing 11 rebounds. He was joined in the double-double category by Marshall Plumleee who finished with 10 points and 11 boards in only 20 minutes of action.
The wing rotation of Matt Jones, Luke Kennard, and Grayson Allen averaged a +19.3 rating amongst them.

- The offensive explosion translated into the season rankings in a number of ways - the biggest changes occurring in the per minute ratings where every player on the roster saw an increase in his score aside from Vrankovic, who had a 1.000 entering the game. - Brandon Ingram is closing in on the top spot occupied by Allen. The freshman continues to score hugely each time out, and while Allen has done well himself, averaging nearly a +20 over the season, Ingram’s ability to rebound, and accumulate blocks and steals (along with his scoring ability) is enough to make moves.
