Efficiency Ratings: Gonzaga

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:

With their trio of freshmen starting, the Duke Blue Devils are going to their 16th Final Four, and a record-tying 12th for Krzyzewski, after a 66-52 win over Gonzaga on Sunday to win the South Regional.

Justise Winslow, the freshman playing at home in Houston, finished with 16 points after rolling his left ankle early in the game and had a big 3-pointer in the closing minutes. Tyus Jones scored 15 points, while Jahlil Okafor had nine points and eight rebounds.

Duke (33-4), the region's No. 1 seed, is going to Indianapolis to play Michigan State in the Final Four. At the Westgate SuperBook, the Blue Devils opened as a 4.5-point favorite over the Spartans. The other national semifinal game Saturday has undefeated Kentucky playing Wisconsin.

With 12, Krzyzewski matches UCLA's John Wooden for the most Final Four appearances by a head coach. There are three coaches with seven, including Michigan State's Tom Izzo.


(change from previous game)
  • Jahlil Okafor +11 (+3)
  • Justise Winslow +15 (-11)
  • Tyus Jones +18 (+5)
  • Quinn Cook +8 (-3)
  • Amile Jefferson +4 (-3)
  • Grayson Allen -1 (-7)
  • Matt Jones +19 (+20)
  • Marshall Plumlee +1 (+1)

Notes: After struggling with his shot, sophomore Matt Jones had his Andre Dawkins versus Baylor moment against Gonzaga. Jones knocked down six of 10 attempts from the field and added three boards and a steal to help Duke to the Final Four. It resulted in a +19 score, which was his highest total of the season.

For the first time all season, Jahlil Okafor has been held to single digit scoring in consecutive games. The big man shot just 40 percent from the field (28 percent lower than his season average) and just 33 percent from the charity stripe. Those totals were enough to pull his score down, but Okafor contributed eight rebounds, an assist, a block, and a steal which buoyed it back up to a +11.

In the backcourt, Tyus Jones missed eight of 13 field goal attempts, but hit all of his free throws and added three rebounds to a six to zero assists-to-turnover ratio to post a +18. Meanwhile, Cook scored and rebounded well (10 and 5), and he didn’t have a turnover in 40 minutes of action. However, the senior’s 2-of-10 shooting performance pulled down his score to a +8.


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