Efficiency Ratings: Toledo

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

Who had the better game? Using the above referenced formula player B, who hit five of eight shots and committed two turnovers registered a +20 efficiency total while Player A who missed 17 shots and had four turnovers had just a +11 rating.


Freshman center Jahlil Okafor scored a season-high 27 points and No. 2 Duke beat pesky Toledo 86-69 on Monday night.

Quinn Cook added a season-best 20 points and Tyus Jones had 15 for Duke (11-0), which was playing its first game since Dec. 18.

The Blue Devils raced out to a big early lead, then allowed Toledo to shoot itself back into the game before eventually pulling away.

Okafor was 12 of 15 from the field while reaching the 20-point mark for the fourth time in six games.

Julius Brown scored 19 for Toledo (7-5), which erased most of a 14-point deficit by making 13 of 15 shots over a 9½-minute stretch. Brown's 3-pointer about 90 seconds into the second half cut Duke's lead to 47-44.

Okafor then reeled off seven straight points to start the decisive 21-9 spurt.


(change from previous game)

Notes: Okafor’s big night was the headline, but Jones was nearly as efficient from his position, scoring a career best +27 (tying his performance against Army) with 15 points and an 8-to-1 assist to turnover ratio. Jones also shot a perfect 9-for-9 from the charity stripe.

Meanwhile, Okafor was dominant and Duke went to the big guy on numerous trips. He hit 12-of-15 from the floor to finish with 27 points and eight rebounds. If Okafor improved his shooting from the free throw line, things would be even better. He finished just three of six on Monday night.

Quinn Cook was the third head of the Duke offensive monster, scoring 20 points on 50 percent shooting overall and a perfect night at the free throw line. Fellow captain Amile Jefferson didn’t factor into the scoring column much (2 points), but his eight rebounds were good enough to keep him in double figure efficiency points.


Throughout the season TDD will track the various highs and lows using the formula.
