Efficiency Ratings: Arizona

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 wasn't a marquee matchup of freshmen, although both of the young stars showed how bright their futures can be.

Instead, No. 4 Arizona's 72-66 victory over No. 6 Duke on Friday night in the championship game of the NIT Season Tip-Off was a chance for two junior guards to take the spotlight.

Nick Johnson scored all but two of his 15 points in the second half and T.J. McConnell had 10 points and eight assists to lead the Wildcats to the win that showed just how versatile a team they are.

Parker, who had 19 points for his first game with fewer than 20 points this season, struggled against Arizona's physical defense and was 7 of 21 from the field. He came into the game shooting 60 percent from the field.

"Jabari gets a lot of attention and it was a good physical game," Duke coach Mike Krzyzewski said. "His shots just didn't go down."

Hood led Duke with 21 points and eight rebounds. The Blue Devils' other loss was to No. 2 Kansas.

"We talked all year about we don't have a center, and we have good players, and we have to figure out how to be good with the players we have," Krzyzewski said. "So I thought those kids played really well. I mean, I thought they played their hearts out."

v. Arizona
(change from previous game)

Notes: Parker posted a season low +5 rating thanks to a rough night shooting (7-of-21), a season low rebounding total (3), and five turnovers.

As a team, the Blue Devils posted just a +61, which was the lowest rating of the season. Only Quinn Cook and Rodney Hood managed to get to double figures, while only Josh Hairston posted more than a +5. In short, it was a rough night for Duke as Arizona's length and depth seemed to wear the Blue Devils down.

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 +14/+1
  • Quinn Cook +29/+8
  • Rasheed Sulaimon +25/+2
  • Tyler Thornton +15/+0
  • Matt Jones +12/-3
  • Alex Murphy +6/-3
  • Josh Hairston +8/+0
  • Semi Ojeleye +16/-1
  • Andre Dawkins +19/-3
  • Marshall Plumlee +3/-1

Notes: Parker's rough night was enough to hurt Duke, but the Blue Devils did get a season best performance from Hairston. In the season rankings, Tyler Thornton moves into fourth place in the season totals - something nobody would have expected in October. Thornton has jumped over both Sulaimon and Jefferson who are struggling shooting (especially Jefferson from the free throw line where he's hitting 33 percent). In order for the Blue Devils to move forward, they'll need more from each player.
