Efficiency Ratings: Alabama

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 matched his season-high with 27 points, setting the school record for consecutive 20-point games to start a career and the sixth-ranked Blue Devils beat Alabama 74-64.

The Blue Devils (6-1), who committed a season-high 19 turnovers, will face No. 4 Arizona, which beat Drexel 66-62, in the championship game on Friday at Madison Square Garden. It's a matchup of the program with the most NIT Season Tip-Off titles — Duke with four — against one of three programs tied for second with three.

The Blue Devils are 23-7 at Madison Square Garden under Krzyzewski and they have won 15 of their last 17 games there. Duke has won 27 straight regular-season tournament games.

Notes: Parker was his usual brilliant self. He was the team's top scorer, rebounder, and defender. His +30 score would have been higher had it not been for five turnovers - three of them early when Duke as a team started 1-of-11 from the field. Parker scored over 20 points for the seventh straight game, a Duke record.

The second half of Duke's dynamic duo, however, endured his worst game as a Blue Devil. Rodney Hood fouled out in just 18 minutes of action, scored just eight points, recorded just one rebound, and turned it over three times. It left the Blue Devils at a scoring deficit for much of the game, and produced just a +3 for Hood.

After the debacle against Vermont, Coach Mike Krzyzewski made a couple of lineup changes. He started Tyler Thornton and Josh Hairston over Rasheed Sulaimon and Amile Jefferson. In Thornton's case, the senior captain produced on the offensive end. He scored six points, grabbed four rebounds, handed out four assists, and came up with five steals. It resulted in a season high +15 rating. Hairston, however, produced just a +4 with two points and two rebounds in 20 minutes before fouling out.

Duke did get a lift off the bench from freshman Matt Jones who scored 13 points and grabbed three rebounds in only 16 minutes of action.

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/+24
  • 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 +6/+0
  • Semi Ojeleye +16/-1
  • Andre Dawkins +19/-3
  • Marshall Plumlee +3/-1

Notes: Parker is, without question, running away as the efficiency leader. Tyler Thornton and Matt Jones both used big performances against Bama to jump up in various tables. Meanwhile, Duke is still not ready (it appears) to give Marshall Plumlee or Semi Ojeleye regular minutes against top opponents.
