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
Jaron Blossomgame scored 17 points, including the clinching dunk with 13.5 seconds left, to lift Clemson to a 68-63 victory over No. 9 Duke on Wednesday night. The victory was the fourth straight for the Tigers (11-6, 4-1 Atlantic Coast Conference) and the third in a row over an NCAA champion in the past eight days following wins at Syracuse and No. 21 Louisville.
Grayson Allen led Duke with 17 points, three off his season average.
Freshman Brandon Ingram scored 16 points for the Blue Devils, all but one in the first half.
The key to the game, Duke coach Mike Krzyzewski thought, came near the end of the opening half when Derryck Thornton missed a 3-pointer and Ingram picked up his third foul scrambling for the rebound.
Blossomgame hit both foul shots to cut the lead to 35-33 at the break.
(change from previous game)
- Grayson Allen +13 (-1)
- Matt Jones +4 (-9)
- Brandon Ingram +13 (-12)
- Amile Jefferson +DNP (-)
- Marshall Plumlee +13 (-18)
- Luke Kennard +9 (-1)
- Derryck Thornton +8 (+5)
- Chase Jeter +1 (-)
- Antonio Vrankovic DNP (-)
- Sean Obi DNP (-)
Notes: Duke was collectively limited on the offensive end against Clemson as the Tigers made an effort to keep the Blue Devils off the foul line. As a team Duke shot just 2-of-7 from the charity stripe and, outside of Marshall Plumlee (9), didn’t rebound overly well (just 21 rebounds as a team)
Certainly the narratives changed after halftime, but before the break Brandon Ingram was rolling along with 15 first half points. The freshman was limited to just one point in the second half and thusly saw his score drop with missed shots and a general lack of rebounding as he was forced to change his approach with heavy foul trouble.

Tracking the most and least efficient performances by player
- Grayson Allen 38/-4
- Amile Jefferson 26/21
- Brandon Ingram 38/-2
- Matt Jones 25/0
- Marshall Plumlee 31/4
- Luke Kennard 28/0
