Efficiency Ratings: Connecticut

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.

LATEST GAME

Freshman point guard Tyus Jones scored 21 points, Justise Winslow hit two key baskets late in the game and Duke beat defending national champion Connecticut 66-56 on Thursday night.

Connecticut (4-4) managed to tie the game at 30 after the time out , but Duke responded with a 15-2 run and never lost the lead.

Winslow and Jahlil Okafor — the other two members of the Blue Devils' trio of talented freshmen — added 12 points apiece. Amile Jefferson added 11 points and 13 rebounds in a game that had the feel and intensity of a NCAA tournament contest.

Duke has won all 10 of its games by at least 10 points, but this one was a lot closer being played in the Izod Center in the Meadowlands sports complex before a near sellout, pro-Huskies crowd.

vs. CONNECTICUT

(change from previous game)


Notes: After a somewhat pedestrian game against Elon, Tyus Jones rose to the occasion in a very big way against the defending champs and their electric guard, Ryan Boatwright. Jones shot the ball well (5-of-11) from the field and the free throw line (9-of-10), and contributed on the boards (6). He did register a season low three assists and matched that low with a high turnover count of the same number. The 1-to-1 ration lowered his otherwise huge score.

In the middle, Duke dominated (and ultimately won) the game against the Huskies with Connecticut having no answer for the star, Jahlil Okafor, or the glue guy, Amile Jefferson. Okafor shot just three of five from the floor, but went to the line an additional 11 times. Were the big man to improve his free throw shooting even marginally (he shot 6-of-11), Duke would be even better.

Meanwhile, Jefferson has a very solid game from the line (5-of-7) and pulled in a game high 13 rebounds, making a living whenever Connecticut attempted to double Okafor.

The biggest concern of the night is the production of the bench where four reserves combined for an aggregate score of -4 while playing 30 minutes. Sulaimon was particularly inefficient, scoring the lowest rated game of the season by any player.

Tracking the most and least efficient performances by player
  • Jahlil Okafor 37 / 13
  • Amile Jefferson 30 / 7

  • Marshall Plumlee 17 / 1
  • Matt Jones 16 / -2


Notes:

- Jefferson and Okafor continue to separate themselves from the pack with consistently big nights. A number of high percentage looks mixed in with the rebounding prowess and a lack of turnovers has allowed the two players to move to, and set up shop at the top of the table.

- After a brilliant start to the season there may be some worry about Cook’s game slowing down a bit. The senior has gone from Duke’s most efficient player to fourth, and were it not for the spotty production of the second half of the rotation it could be an even bigger drop. The biggest factor in the captain’s fall from the top? A shooting percentage that continues to dip.
