Efficiency Ratings: Georgetown

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:

Grayson Allen scored a career-high 32 points, and the Blue Devils beat Georgetown 86-84 on Sunday at Madison Square Garden.

Derryck Thornton had 14 points and Matt Jones scored 11 for the Blue Devils (4-1), who trailed by five at halftime.

Allen bounced back nicely after he scored six points on 2-for-11 shooting in Tuesday night's 74-63 loss to the second-ranked Wildcats..

The Blue Devils also won this event in 2008 when they beat Michigan State by 15 and Kyle Singler was named MVP. ... Duke is 9-0 when Allen scores in double figures.

vs.GEORGETOWN

(change from previous game)

  • Grayson Allen +38 (+7)
  • Matt Jones +8 (-)
  • Brandon Ingram +2 (-)
  • Amile Jefferson +9 (-)
  • Marshall Plumlee +11 (+1)
  • Luke Kennard +6 (+4)
  • Derryck Thornton +10 (-6)
  • Chase Jeter +4 (+4)
  • Antonio Vrankovic DNP (—)
  • Sean Obi DNP (—)

Notes: Allen’s second straight career night gives him a +69 rating over the last two games - the highest two game stretch in our six seasons of tracking efficiency for Duke. It’s not just the scoring that’s pushing Allen’s score so high, it’s also his shooting performances (9-of-12 against Georgetown). To score so many points on so few shots is an easy way to push good scores into great. And, Allen’s performance was one of the top scores we’ve even seen in these ratings. The performance was reminiscent of Kyrie Irving’s game against Arizona at the end of the 2011 season.

The only other Blue Devils to crest the +10 scoring point were Marshall Plumlee and Derryck Thornton. Thornton’s score was buoyed by his 8-of-10 performance at the free throw line while Plumlee’s perfect night from the field and six rebounds helped up his total.

  • Derryck Thornton 16/2
  • Sean Obi 0/0

Notes:

- Allen has left the pack much like Jahlil Okafor and Jabari Parker in the previous two seasons, opening up a 28 point advantage on his closest competition. He’s also maintaining a lofty position in the per minute ratings despite playing the most minutes on the season.

- Duke continues to wait on Brandon Ingram’s adjustment period to end and for the very talented freshman to engage on the offensive end. He’s ranking sixth on the team in per game efficiency and has been very poor at the free throw line this year.

- Similarly, Duke is hoping Luke Kennard can break out of his shooting slump. The 6’5 lefty guard is averaging just 6.0 points per game in the efficiency scoring. That’ll go up once he starts knocking down shots.
