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
Tyler Roberson had 14 points and a career-high 20 rebounds, and the Orange beat the Blue Devils 64-62 on Monday night, the Blue Devils' third straight loss.
Roberson set the arena record for rebounds by a visitor, breaking the previous mark of 18 set in 1957 and most recently matched by North Carolina's Sean May in 2005.
Marshall Plumlee had 19 points and 17 rebounds to lead Duke (14-5, 3-3). After receiving their lowest national ranking in two years earlier in the day, the reigning national champs now have their longest losing streak since the 2006-07 team dropped its final four games and are in danger of falling out of the poll for the first time since that season.
"The game is tremendous, and it can be incredibly great to you, and it can be incredibly cruel to you," Duke coach Mike Krzyzewski said. "And right now, we're going through the cruel part."
(change from previous game)
- Grayson Allen +12 (-6)
- Matt Jones +8 (+3)
- Brandon Ingram +17 (-6)
- Amile Jefferson +DNP (-)
- Marshall Plumlee +33 (+15)
- Luke Kennard -3 (-33)
- Derryck Thornton +6 (+2)
- Chase Jeter DNP (-)
- Antonio Vrankovic DNP (-)
- Sean Obi -1 (-2)
Notes: Less than 48 hours after posting a career best +30 against Notre Dame, Luke Kennard felt the cruel part of the game as Coach K called it, posting a career low -3. It’s the largest two game variance in the history of these ratings.
Meanwhile, Duke didn’t get great games from either Ingram or Allen, which has been a constant in each of the five losses this season. One can be very good, but the other must be better than that (or both). When both are just ‘good’, Duke doesn’t have enough to push past good opponents.
Marshall Plumlee continued his run of strong and efficient play, logging another career high with +33.
