Efficiency Ratings: Vermont

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.

Jabari Parker scored 26 points in his sixth straight 20-point performance. Rodney Hood finished with 22 for Duke (5-1), which extended its nonconference winning streak at Cameron Indoor Stadium to 106 games.


Duke blew a 15-point lead and allowed Vermont to shoot 64.8 percent before — depending on the perspective — it either got the one defensive stop it needed, or the Catamounts simply ran out of time.

Andre Dawkins scored 16 points and Quinn Cook added 14 for the Blue Devils.

The Blue Devils advanced to next week's semifinals in New York's Madison Square Garden.

v. Vermont
(change from previous game)

Notes: Once again Parker was brilliant, while Hood was very good. The two combined for 48 points and 16 rebounds. But for Duke to reach its potential, the Blue Devils have to get more from various players throughout the lineup and rotation...

For starters, Duke needs more from two starters: Amile Jefferson and Rasheed Sulaimon. The sophomores have been almost non-existent on both ends of the floor for extended periods of times. That was the case against the Catamounts, who were never bothered by the combined four points in 38 minutes.

By leading the team in scoring and rebounding, and shooting 11-of-16 from the field, Parker scored a +30, which is his best to date.

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

Tracking the most and least efficient performances by player

  • Rodney Hood +32/+6
  • Jabari Parker +30/+24
  • Amile Jefferson +14/+5
  • Quinn Cook +29/+8
  • Rasheed Sulaimon +25/+2
  • Tyler Thornton +11/+0
  • Matt Jones +6/-3
  • Alex Murphy +6/-3
  • Josh Hairston +6/+0
  • Semi Ojeleye +16/-1
  • Andre Dawkins +19/0
  • Marshall Plumlee +3/-1

Notes: Quinn Cook continues to bolster his averages with scoring and a huge assist to turnover ration (43-to-8). Sulaimon and Jefferson posting season lows against Vermont allowed the Catamounts to stay within striking distance, and then cut the margin before taking the lead late. Duke has gotten precious little from the post as a group, and needs more from the trio of Marshall Plumlee, Semi Ojeleye, and Amile Jefferson.
