Efficiency Ratings: Wisconsin

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

Tyus Jones scored 22 points, Rasheed Sulaimon added 14 and No. 4 Duke shot 65 percent to beat No. 2 Wisconsin 80-70 on Wednesday night in a highly anticipated matchup of college basketball heavyweights.

With 17 points, Wisconsin senior Frank Kaminsky outscored Duke freshman Jahlil Okafor (13 points) in a test for the two of the nation's top big men.

But it was another touted freshman, Jones, who helped open things up for the Blue Devils (8-0) in the second half. The lightning-quick guard beat defenders into the lane and added two 3-pointers.

Jones followed a transition layup with an assist on Amile Jefferson's jumper to cap a 6-0 run that gave Duke a 69-60 lead with about 3 minutes left against the Badgers (7-1).

vs. WISCONSIN

(change from previous game)
  • Jahlil Okafor +17 (-3)
  • Justise Winslow +6 (-1)
  • Tyus Jones +25 (-2)
  • Quinn Cook +11 (-1)
  • Rasheed Sulaimon +16 (+4)
  • Amile Jefferson +10 (-7)
  • Grayson Allen — (-)
  • Matt Jones +4 (-2)
  • Semi Ojeleye - (-)
  • Marshall Plumlee +6 (-8)



Notes: Jones was not only extremely effective against the Badgers, he was also quite efficient, shooting 7-of-11 from the floor and 6-of-8 from the charity stripe. The point guard was also the team’s leading rebounder and top assist man. It was an upperclassman level performance on the biggest stage of the season - which was exactly the scouting report on Jones coming into Duke.

In the biggest matchup of the night, Jones’ classmate, Jahlil Okafor did well against fell first team All-American Kaminsky. The Duke big man shot 75 percent from the floor and grabbed six rebounds. Foul trouble limited him for an extended period, but Okafor still managed to post the second highest score of the night.

While Jones and Okafor were very good, the most efficient player per minute played was Rasheed Sulaimon, who finished with 14 points in 21 minutes. The junior hit five of his eight shots - most off of dribble drives - and threw in a handful of rebounds and assists (3 and 2).

SEASON HIGH/LOW PERFORMANCES


Tracking the most and least efficient performances by player
  • Jahlil Okafor 32 / 13
  • Amile Jefferson 30 / 7
  • Quinn Cook 24 / 12
  • Tyus Jones 27 / 3
  • Grayson Allen 22 / 0
  • Rasheed Sulaimon 20 / -4
  • Justise Winslow 21 / 5
  • Marshall Plumlee 17 / 1
  • Matt Jones 16 / 2
  • Semi Ojeleye 8 / -2


Notes:

- While Jones and Okafor were great, Justise Winslow struggled for extended periods, logging four turnovers (a season high) and shooting just 2-of-6 from the field. His final line of 5 points, 5 rebounds, and four turnovers was among his least efficient of the season…and yet, he still came up big when Duke needed him, hitting a huge three pointer after Okafor was forced out, and then throwing home an emphatic jam that put the game out of reach.

- Duke got quite a lift from Sulaimon who has played well in back to back games. The junior seems to have found his midrange and dribble drive game, which is extremely tough for teams to guard.

- Coach Krzyzewski seems to have established his big game rotation with sophomore Semi Ojeleye and freshman Grayson Allen on the outside looking in.
