Efficiency Ratings: Miami

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 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.

Less than 48 hours after being beaten by Virginia on the road, Duke returned home to face Miami. Of course this wasn't the same Duke team that had lost to the Cavaliers. That Duke team, in fact, appears to be a thing of the past as the Blue Devils returned their starting power forward and third senior captain. For his part, Kelly was as good as could be. He scored a career high 36 to lead his team to a major victory over the Hurricanes on Saturday. .

(change from previous game)

Notes: Against Virginia the Blue Devils got virtually nothing from the PF position. Fast forward two days and Duke got All-American play from the four spot. Kelly's performance may have been a stored up amount of energy and adrenaline. It may have been circumstantial. Whatever it was, Duke would love to get another couple of doses over the remaining two regular season games and beyond.

Kelly was so good that Coach K called his performance against No. 5 Miami "perhaps one of the best ever in Cameron". It's hard to argue that from an efficiency perspective. The 6'11 senior hit a ratings high +39 (the highest single game mark we've ever tracked), and helped his team overcome off nights from Sulaimon and Curry.

Speaking of Sulaimon, the freshman guard recorded his second straight negative score thanks to a 4-0 turnover to assist ratio. Much like the game against Virginia, the Houston native seemed to be fighting frustration throughout most of the night. However, his steal and layup in the closing moments proved to be the different in the game.

With his starting front court and classmate returning, Mason Plumlee had a somewhat quiet statistical night with just 12 points and only five rebounds. It resulted in a +15 for the senior.

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: 36/0
  • Quinn Cook: 36/3
  • Tyler Thornton: 16/-3
  • Rasheed Sulaimon: 26/-6
  • Ryan Kelly: 39/10
  • Seth Curry: 26/-8
  • Amile Jefferson: 16/0
  • Alex Murphy: 13/-1
  • Josh Hairston: 12/-1
  • Marshall Plumlee: 2/-1

Notes: Kelly's return and virtuoso performance moved him over .600/minute mark on the per minute ratings. He also bumped up his per game score to 17.5. Despite playing in just 16 games on the season, Kelly has a chance to perhaps catch his freshman teammate, Sulaimon in production though the Texan has shown the ability to have a huge game out of the blue.

Kelly's return meant DNPs for both Amile Jefferson and Alex Murphy.
