Efficiency Ratings: Eastern Michigan

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.

Andre Dawkins stepped right in for Rodney Hood — first in the Duke starting lineup, then in the box score.

Dawkins had season highs of 20 points and six 3-pointers in the ninth-ranked Blue Devils' 82-59 victory over Eastern Michigan on Saturday.

With Hood fighting an illness that he said caused him to flee the court and throw up, Dawkins was summoned from the bench to make a surprise start moments before the opening tip.

And the fifth-year senior who sat out last season sure made the most of it. He finished with his highest point total since scoring 22 and hitting six 3s in a win at Florida State in 2012.

The Blue Devils (10-2) got their requisite big game from freshman phenom Jabari Parker, who scored 23 points.

Rasheed Sulaimon added 13 and came up with the key hustle play during the decisive second-half run that helped them polish off their fourth straight win.

Duke shot 40 percent against Eastern Michigan's tough zone defense while hitting 10 3-pointers, built a 47-32 advantage on the boards and wrapped up the pre-ACC home schedule with its 101st straight nonconference win at Cameron Indoor Stadium.

(change from previous game)

Notes: Parker's +18 was his lowest score in several games. The freshman scored more than 20 points once again, but his score was hit by 11 missed field goals, and a 50 percent performance from the free throw line (4-of-8).

It was the worst scoring output of the season for junior point guard Quinn Cook, but the Duke floor general did manage seven assists and five steals which overcame a 1-of-9 shooting performance to push Cook's score to a +8.

With Hood slowed by illness, Duke got a shot in the arm from Andre Dawkins who posted a +23 score by shooting 6-of-10 from the perimeter (all his FGAs were 3pt attempts) while grabbing three rebounds, blocking two shots, and collecting two steals.

A point of contention in the rotation could be at the power forward position where Josh Hairston logged 11 minutes resulting in a -1 rating after his stat line accounted for only one rebound and two turnovers in that time. His replacement, Amile Jefferson, continued to gobble up more minutes and produced in those 21 ticks, grabbing 14 rebounds and scoring seven points -- the most encouraging stat in Jefferson's +17 rating? Making all five of his free throw attempts.

Throughout the season TDD will track the various highs and lows using the formula.
