Efficiency Ratings: VCU

As the Blue Devils progress through the season there will be many different theories on how to measure team success. TDD has adopted an NBA Efficiency Formula to track Duke's top players and performances after each game and throughout 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:

Just three days after a rough performance against No. 2 Kentucky, Duke's sophomore guard came up with a career-high 30 points as the fifth-ranked Blue Devils beat VCU 79-71 on Friday night in the opening round of the 2K Classic at Madison Square Garden.

Duke turned up the defense when it needed to in the second half.

From their last lead with 12:03 to play, the Rams (2-1) went 5 of 20 from the field and Duke had a lot to do with that, especially inside where easy baskets in the first half were being challenged and that led to some breakouts for the Blue Devils.

Freshman Derryck Thornton, who started in place of Allen, had a career-high 19 points for Duke, and Matt Jones added 10, including two big 3s in the second half. Jones came into the game shooting 56.3 percent (9 of 16) from 3-point range.


vs.VCU

(change from previous game)

  • Grayson Allen +31 (+35)
  • Matt Jones +8 (-5)
  • Brandon Ingram +2 (+4)
  • Amile Jefferson +9 (-17)
  • Marshall Plumlee +10 (-13)
  • Luke Kennard +2 (+2)
  • Derryck Thornton +16 (+11)
  • Chase Jeter DNP (—)
  • Antonio Vrankovic DNP (—)
  • Sean Obi DNP (—)

Notes: Grayson Allen’s efficiency rating would make for a tremendous roller coaster in any theme park is in the market. The sophomore followed up a huge dip with an even larger rise, posting a score that 35 points higher than his previous game. That came on the heels of a -30 dip from the Bryant game to UK. With Duke needing to go small (and to find a point guard option), Derryck Thornton had a very good game, scoring 19 points and shooting 7-of-11 from the field for a +16 rating - his highest of the season. Meanwhile, Brandon Ingram and Amile Jeffers both saw their scores lowered tremendously thanks to a combined 6-for-18 performance from the free throw line.
