Efficiency Ratings: Clemson

Using an NBA Efficiency Rating Formula, TDD tracks the best statistical performances of the season.

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

Latest Game:

No. 4 Duke was shorter and faster without Jahlil Okafor. The Blue Devils were no less dominant.

They routed Clemson 78-56 on Saturday when Quinn Cook matched a career high with 27 points and Justise Winslow added 20 points and 13 rebounds.

Three freshmen -- Winslow, Tyus Jones (11) and Grayson Allen (10) -- reached double figures to help Duke (24-3, 11-3 Atlantic Coast Conference) win its seventh straight.

With the 6-foot-11 Okafor out with a sprained left ankle, the Blue Devils went small and quick. They scored 19 fast-break points and outscored the Tigers 42-30 in the paint, largely on drives and layups.

The Tigers pulled to 51-41 on Damarcus Harrison's jumper with just under 14 minutes left.

Allen countered with a 3, and then Cook made two big plays: He buried a corner 3 while falling into Duke's bench, then put the Blue Devils up 20 for the first time with a fast-break layup that made it 61-41 with about 10 minutes to play.

Winslow and Cook came up big without their biggest teammate.


vs. CLEMSON

(change from previous game)
  • Jahlil Okafor DNP (-)
  • Justise Winslow +28 (+10)
  • Tyus Jones +16 (-6)
  • Quinn Cook +27 (+11)
  • Amile Jefferson -1 (-21)
  • Grayson Allen +10 (+10)
  • Matt Jones +6 (-4)
  • Marshall Plumlee +5 (+3)



Notes: Winslow, Cook and Tyus Jones were terrific and combined for a +71 while playing a ton of minutes between them. Winslow’s double-double of 20 points and 13 rebounds was enhanced by his four steals as well. Meanwhile, Cook’s career high tying 27 points was helped by his great shooting (11-of-18) and four assists. Jones’ 11 points and nine rebounds was just as good, but was pulled down by his shooting from the field (2-of-7).

The only spot of concern for the game was the performance of Amile Jefferson who came off a +20 against North Carolina to post his season low against Clemson with just two points and no rebounds in 16 minutes.
