Efficiency Ratings: Georgia Tech

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.

Rodney Hood scored 15 of his 27 points in the second half, and No. 16 Duke beat Georgia Tech 79-57 on Tuesday night.

Quinn Cook added 13 points and slumping freshman Jabari Parker had 12 on 4-of-12 shooting for the Blue Devils (12-3, 1-1 Atlantic Coast Conference).

Playing their first game outside the top 10 since November 2007, they spent half the night proving they deserved their drop before Hood helped them pull away for their 25th straight win at Cameron Indoor Stadium.

The Blue Devils struggled for much of the game to slow down a Georgia Tech offense that entered 12th in the 15-team ACC in both scoring and field goal percentage, averaging 71 points and making under 43 percent of its shots.

The only thing resembling a Duke run came early in the second half when Sulaimon's 3-pointer capped a quick 12-3 burst that gave the Blue Devils their first double-figure lead, 48-38, with 16½ minutes left.

v. Georgia Tech
(change from previous game)

Notes: Parker's struggles were obvious as the freshman struggled to get any lift on his shots before attempting to force things a bit with wild one against several drives to the basket that resulted in a pair of turnovers. Still, the Chicago native was perfect at the free throw line and recorded 12 points and six rebounds. Interestingly enough, some of Parker's versatility as a facilitator has suffered over the last few games (he's logged just three assists over his last four games and none in the last two), and his shooting percentage has continued to dip as well (he was 4-of-12 against Tech). The eight missed shots coupled with a 0/2 assist to turnover ratio resulted in his second lowest score of the year, a +8 - more than 12 points below his season average.

With Parker off his game, captain Rodney Hood has certainly found his rhythm of late. The 6'8 sophomore scored 27 points on just 12 shots and added six rebounds and three assists to post a +31 - his second highest score of the season.

Returning starters Amile Jefferson and Rasheed Sulaimon recorded +16 and +13. For Jefferson, the production was +1 over his replacement's production over the last five games combined.

Off the bench Duke got a boost from Dawkins who logged 25 minutes to score 10 points and grab three rebounds despite just 2-of-7 shooting. Sophomore center Marshall Plumlee logged a +1 in two minutes via a blocked shot.

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/-1
  • Amile Jefferson +17/+1
  • Quinn Cook +31/+8
  • Rasheed Sulaimon +25/-2
  • Tyler Thornton +15/+0
  • Matt Jones +12/-3
  • Josh Hairston +8/-1
  • Semi Ojeleye +16/-1
  • Andre Dawkins +23/-3
  • Marshall Plumlee +7/-1

Notes: Parker still has a commanding lead on the cumulative table, but Hood's two big games mixed with Jabari's two poor performances have kept the sophomore within striking distance. The backcourt rotation seems to be ironing out both on the court and in the team rankings as Sulaimon and Dawkins are beginning to separate from Tyler Thornton, while Matt Jones has faded down.
