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
Bonzie Colson scored a career-high 31 points and grabbed 11 rebounds, and Notre Dame upset No. 9 Duke 95-91 on Saturday.
Demetrius Jackson added 24 points and Steve Vasturia finished with 22 to help the Fighting Irish (12-5, 3-2 ACC) win their second straight and beat the Blue Devils for the fourth time in five tries.
Freshman Luke Kennard had a season-best 30 points and Brandon Ingram added 25 for the Blue Devils (14-4, 3-2), who have lost two straight for the first time this season.
Grayson Allen finished with 18 points, and he put Duke up 89-88 with two free throws with 47.2 seconds left. Colson then converted a key three-point play with 35.8 seconds remaining to give Notre Dame the lead for good.
(change from previous game)
- Grayson Allen +18 (+5)
- Matt Jones +5 (+1)
- Brandon Ingram +23 (+10)
- Amile Jefferson +DNP (-)
- Marshall Plumlee +18 (+5)
- Luke Kennard +30 (+21)
- Derryck Thornton +4 (-4)
- Chase Jeter +0 (-)
- Antonio Vrankovic DNP (-)
- Sean Obi +1 (+1)
Notes: Kennard and Ingram were top end players against Notre Dame - both scoring in bunches and doing it in an overly efficient manner. The only knock on Kennard was a four turnover tally.
Junior Matt Jones not only missed his second straight attempt to tie a game in the final seconds, but posted just a +5 in the efficiency category. He missed five of eight shots, which isn’t a killer, but the two missed free throws not only hurt his score, but also hurt the chances at pulling out a victory.
Inside, Marshall Plumlee was once again efficient in his efforts by posting nine boards and eight rebounds while missing just two shots.

SEASON HIGH/LOW PERFORMANCES
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 30/0
- Chase Jeter 12/-3
- Antonio Vrankovic 8/1
- Derryck Thornton 20/-5
- Sean Obi 3/0
- Luke Kennard passed Matt Jones as expected with a big time performance and Jones continuing to flounder in the +5 range on a nightly basis. The junior has struggled tremendously in ACC play after putting up strong numbers pre-conference.
- Next up for Kennard would be tracking down Marshall Plumlee for the No.3 spot.
