Efficiency Ratings: Louisville

Using an NBA Efficiency Rating Formula, TDD tracks the best statistical performances of the season

As the Blue Devils progress through the season there will be many different theories on how to measure team success. TDD has adopted the 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

Who had the better game? Using the NBA 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.

Facing, arguably, the best team in the country, and doing so in the third game in three days, the Blue Devils put together a gritty performance to beat Louisville, 76-71 to claim the Battle for Atlantis championship.

Sophomore point guard Quinn Cook took home Tournament MVP honors after the Duke floor general scored 15 points and handed out six assists in the championship game. Over the course of the three game event, Cook averaged 13.7 points, 3.3 rebounds, and 6.3 assists per game while shooting 13-of-28 (.464) from the floor and 15-of-17 (.882) from the free throw line. And he did it on back to back nights against some of the toughest pressure the team will see all season long.

Things don't get any easier for Duke as the Blue Devils return to Durham to face another top five opponent, Ohio State, on Wednesday as part of the ACC/Big 10 Challenge. However, no matter the outcome of that contest, the team has learned a lot about where it is, and where it has the potential to go.

v. Louisville
(change from previous game)

Notes: Fatigue took its toll on several players including Curry who hit a couple of big shots, but was struggled from the field overall (3-of-11). Curry also failed to register a steal, assist or block, but did commit two turnovers which lowered his game score. Meanwhile Tyler Thornton managed a +9 despite making just one of two shots. His score was boosted by three rebounds, three assists, and two steals. Similarly, Ryan Kelly was a stat sheet stuffer, hitting for 14 points, six rebounds, four assists, two blocks, and a steal.

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

Tracking the most and least efficient performances by player

  • Mason Plumlee: 34/17
  • Quinn Cook: 19/7
  • Tyler Thornton: 15/1
  • Rasheed Sulaimon: 15/9
  • Ryan Kelly: 20/10
  • Seth Curry: 26/5
  • Amile Jefferson: 7/0
  • Alex Murphy: 1/0
  • Marshall Plumlee: DNP
  • Josh Hairston: 8/-1

Notes: Through six games, Mason Plumlee has nearly doubled his next closest challenger for the total efficiency point lead. As expected, Plumlee is also running away with the per game and per minute ratings. What's interesting are the secondary clusters of performance. Kelly, Curry, and Cook are within 13 points of one another with Sulaimon still able to move up the chart with a big game or two. At this point it would appear that if Kelly can start knocking down his perimeter jumper (he's shooting just 24 percent from three), he could begin creating some distance in second place thanks to his overall production (blocks, steals, etc). Tyler Thornton's production continues to earn him sixth man minutes, while Duke continues to wait on Jefferson and/or Murphy to earn more time off the bench.
