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
Brandon Ingram scored a season-best 24 points and No. 7 Duke routed Indiana 94-74 on Wednesday night in the Big Ten/ACC Challenge.
Matt Jones added a career-high 23 points with five 3-pointers and Grayson Allen had 16 points for Duke, which won its fifth straight by shooting 53 percent and holding Indiana without a field goal for the first 8 1/2 minutes of the second half.
This was supposed to be one of the marquee matchups of the made-by-TV event, but two losses by Indiana at the Maui Invitational took off some of the luster.
And Ingram and the Blue Devils turned this one into a rather ordinary rout at Cameron Indoor Stadium.
(change from previous game)
- Grayson Allen +20 (-4)
- Matt Jones +20 (+19)
- Brandon Ingram +26 (+12)
- Amile Jefferson +25 (-)
- Marshall Plumlee +6 (-15)
- Luke Kennard +7 (-11)
- Derryck Thornton +16 (+21)
- Chase Jeter DNP (-3)
- Antonio Vrankovic DNP (—)
- Sean Obi DNP (—)
Notes: A very balanced showing for the top seven players on the roster. Only Plumlee didn’t score in double figures in the ratings - primarily due to poor field goal percentage (.333) and free throws (.500). As for the rest of the team, Ingram’s hot shooting (and high percentages) coupled with a respectable six rebounds pushed the freshman to a new career mark in both points and the efficiency score.
Meanwhile, Amile Jefferson posted a second straight +25 score, while Derryck Thornton rebounded from the least efficient game of the season to improve his score by 21 points.

- Ingram is slowing working his way up the per minute efficiency table, passing both Kennard and Jones in this latest update. The 6’9 freshman continued to shoot well and is also beginning to factor in in other areas as well - namely on the glass and on the defensive end of the court.
