Efficiency Ratings: UCLA

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.

It was an average performance from Jabari Parker, and it drew praise worthy of another stellar effort by the Duke freshman.

"He's a natural," Blue Devils coach Mike Krzyzewski said after Parker had 23 points and 10 rebounds in an 80-63 victory over UCLA on Thursday night at Madison Square Garden. "In different sports there are people who are naturals. Jabari is a natural. He can become even better. He embraces the moment."

Parker was 7 of 13 from the field, including a 4-for-8 performance from 3-point range. He also was 5 of 5 at the free throw line and had five assists while scoring at least 20 points for the ninth time in his 11 college games.

The Blue Devils (9-2) poked and prodded UCLA's 2-3 zone from the perimeter, making 11 3-pointers in a season-high 32 attempts from beyond the arc.

Rodney Hood and Quinn Cook both had 14 points for the Blue Devils. Cook had five assists and all eight of Duke's steals.

(change from previous game)

Notes: As Krzyzewski noted, Jabari Parker was brilliant with his play once again. Parker led the team in scoring, rebounding, and assists while playing 37 of a possible 40 minutes. The +30 score for Parker was tied for his best game of the season.

Though Parker was great once again, Duke really benefitted from a balanced attack that featured the lineup many expected to see at the beginning of the season with Amile Jefferson, Quinn Cook, Rodney Hood, and Rasheed Sulaimon joining Parker on the court in crunch time. Each of those players produced double-digit efficiency numbers highlighted by Sulaimon's +11 score. While it was the lowest of the five, it represented a huge swing in momentum for the sophomore who had logged just five minutes in the last two contests. Jefferson added 11 points and seven rebounds while Cook's score suffered from a tough shooting night and a season high four turnovers, but was saved with a career best eight steals from the junior.

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/+3
  • Jabari Parker +30/+5
  • Amile Jefferson +16/+1

  • Marshall Plumlee +4/-1

Notes: Sulaimon's turning point game (perhaps?) bumped him back up the per minute and season rankings. The most intriguing battle appears to be happening at the top where Quinn Cook is within a game or two of catching Hood for the second spot.
