Efficiency Ratings: East Carolina

As the Blue Devils progress through the season there will be many different theories on how to measure team success. TDD has adopted an NBA Efficiency Formula to track Duke's top players and performances after each game and throughout 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 a career-high 30 points Tuesday night to help sixth-ranked Duke beat East Carolina 83-74 in the NIT Season Tipoff.

Freshman Jabari Parker had 21 points and nine rebounds for the Blue Devils (4-1), who survived a tougher-than-expected fight from the underdog Pirates to improve to 24-2 all-time in the early season tournament.

Duke led by a single point with about 7 minutes left but stayed in front and did enough in the final 2½ minutes to turn away East Carolina (4-1).

Duke led by 18 points late in the first half after a hot-shooting start, but the Pirates didn't let the Blue Devils put together a knockout run. Instead, the Pirates closed the gap to 11 by halftime, and then kept inching closer and closer after halftime.

Duke finished 24 for 31 from the foul line, including 19 for 24 after halftime.

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

v. East Carolina
(change from previous game)

Notes: Parker did a little bit of everything on Tuesday. The freshman scored, rebounded, and blocked shots. So why was his efficiency rating lower than last game? The answer lies in his field goal percentage (8-of-18) and free throw shooting (4-of-7). It's nitpicking at this point as Parker has clearly been Duke's most dynamic player and his per game efficiency scores are the highest over five games since we began tracking.

Hood, meanwhile, put together yet another huge stat line. The third year sophomore scored (30 points), shot the ball efficiently (80 percent from the field and 100 percent from the line), and managed to rebound a bit (5) as well. It resulted in the season's highest efficiency score of +32.

In the first half it appeared as though Duke could do no wrong after hitting their first 11 shots. Squarely in the middle was Quinn Cook who dished out seven assists and shot the ball well. However, Cook cooled off after halftime but managed to finished with 14 points and 10 assists against only two turnovers. His +17 score was over his season average and would have been higher but for some poor shot selection at times after intermission. For the game Cook shot just 5-of-15.

Off the bench Duke didn't get much in the way of scoring (just six points combined). Most notable in the fall was Semi Ojeleye who earned just five minutes and recorded 2 rebounds and a block. Andre Dawkins managed just 11 minutes and scored two points.

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 +29/+24
  • Amile Jefferson +14/+9
  • Quinn Cook +29/+8
  • Rasheed Sulaimon +25/+5

Notes: Jabari Parker and Rodney Hood continue to run a close(ish) race for the top overall cumulative score, while Parker's reduced minutes (he's played 26 fewer than Hood) keep him comfortably ahead in the per minute category. After the top two, there is a second tier of Cook with Amile Jefferson and Rasheed Sulaimon capable of closing the gap with extended minutes - something neither has been able to manage so far. Tyler Thornton may not score a ton, but his all around contributions have him averaging a career best +8/game. His minutes, however, have been cut short due to an average of 3.8 fouls per game.
