Efficiency Ratings: Florida State

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.

The message from Coach K was to jump on Florida State early. To push the tempo and not look back against the sporadic offense of the Seminoles. That message was received loud and clear as Duke jumped out to a 18-2 lead and would eventually lead by as many as 28 before coasting to a 19 point win in Tallahassee on Saturday. The victory pushed Duke's record to 19-2 overall and 6-2 in ACC play, just two games behind league leader Miami. Next up is a chance for redemption against NC State in Durham.

v. Florida State
(change from previous game)

Notes: Mason Plumlee had a relatively quiet offensive performance, scoring just eight points to go with five rebounds in only 25 minutes of action. Still, the perfect day from the field (4-of-4) combined with the rebounding, three blocks, two steals, and two assists were enough to push him to a respectable +18.

Similarly, Curry and Cook enjoyed great shooting performances (combined 14-of-23) en route to posting a pair of +23 scores. Cook scored 18 points and handed out six assists against just one turnover. For the season, Cook has a 131-46 assist to turnover margin.

Off the bench, Duke didn't get a lot on the offensive end from either Murphy or Marshall Plumlee. The two players combined for 19 minutes and just a -1 cumulative rating. Neither hit a field goal, and Murphy's two rebounds and one steal was cancelled out by his three turnovers.

In the per minute category, Plumlee scored a .720 per minute offensive efficiency rating while Cook was at .719. None of it was good enough to pass Curry who posted a ridiculous .852/minute clip.

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

Cumulative Season ratings for the Blue Devils. (E/game)*

  • Quinn Cook: 322 (15.3)
  • Seth Curry: 243 (12.2)

  • Ryan Kelly: 229 (16.4)
  • Amile Jefferson: 127 (6.4)
  • Tyler Thornton: 126 (6.0)
  • Josh Hairston: 61 (2.9)
  • Alex Murphy: 44 (2.3)
  • Marshall Plumlee: 0 (0.0)

Cumulative Season ratings per minute for the Blue Devils. (E/minutes)

  • Mason Plumlee: 0.683
  • Ryan Kelly: 0.573
  • Amile Jefferson: 0.483
  • Quinn Cook: 0.455
  • Seth Curry: 0.402
  • Rasheed Sulaimon: 0.379
  • Alex Murphy: 0.352
  • Tyler Thornton: 0.285
  • Josh Hairston: 0.236
  • Marshall Plumlee: .000

Tracking the most and least efficient performances by player

  • Mason Plumlee: 35/9
  • Quinn Cook: 36/6
  • Tyler Thornton: 16/-3
  • Rasheed Sulaimon: 16/-6
  • Ryan Kelly: 23/10
  • Seth Curry: 26/-8
  • Amile Jefferson: 16/0
  • Alex Murphy: 13/-1
  • Marshall Plumlee: 2/0
  • Josh Hairston: 9/-1

Notes: Mason Plumlee continues to be the standard for these ratings and is closing in on the highest cumulative total and per game totals since we began keeping track of these statistics several years ago. This highest was Nolan Smith during the 2011 season (the year he won ACC Player of the Year honors) at 20.92.

Despite missing six games, Ryan Kelly still ranks in the top five of the cumulative scoring, and second on the team with a +16.4 per game average. Kelly is expected to return later this month.

Freshman Amile Jefferson has taken advantage of his extended minutes since Kelly went down, and has shot up the charts in the cumulative and seasonal averages. Jefferson's +16 against FSU was his season high, and after 21 games he has passed Tyler Thornton in cumulative offensive efficiency and has now played more minutes than his co-replacement power forward, Josh Hairston. Jefferson contributes at more than double on the offensive stat tracking formula rate of his junior class teammate.
