Efficiency Ratings: 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.

Duke played the defense its Hall of Fame coach wanted to see, while Quinn Cook turned in an all-around floor game to keep the 10th-ranked Blue Devils rolling in the ACC/Big Ten Challenge.

Cook had 24 points — all in the second half — and nine assists to help Duke beat No. 22 Michigan 79-69 on Tuesday night, improving the Blue Devils to 13-2 all-time in the annual interconference competition.

Freshman Jabari Parker added 15 points to help the Blue Devils (7-2) regroup from last week's loss to Arizona by grinding out a tough win against the Wolverines. Duke didn't shoot the ball well early but frustrated Michigan's offense, turning away every spurt and keeping the Wolverines (5-3) at arm's length much of the game.

Duke coach Mike Krzyzewski said his team played "an outstanding defensive game," which began with forcing the Wolverines to miss 17 of their first 21 shots to put them in a hole they never escaped.

"Each of the teams I've coached here has to develop its own identity, even though we're given a place that's very high before we ever accomplish anything because of our history," Krzyzewski said. "... We're not a great basketball team. We have great kids and they're trying hard. We have a really tough schedule and we have to just keep trying to get better."

v. Michigan
(change from previous game)

Notes: With Duke employing a more balanced attack, both Jabari Parker and Rodney Hood produced quiet +12 ratings. Scores held down by some tough shooting percentages (Parker missed seven shots, while Hood missed eight including four from behind the arc).

Quinn Cook was brilliant against the Wolverines, producing his best all around game of the season and earning a +31 rating for the night. Cook shot less than 50 percent from the field, but countered that with a perfect 10-of-10 from the free throw line mixed in with four rebounds and nine assists against just two turnovers.

Off the bench Duke got much improved support from Amile Jefferson who provided a +16 rating in just 17 minutes of action. Backing up Jefferson was a cameo from Marshall Plumlee who posted a +4 rating (his career best) in just six minutes of action.

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