Efficiency Ratings: Virginia

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.

Rasheed Sulaimon hit the go-ahead 3-pointer with 18.8 seconds left and No. 23 Duke beat Virginia 69-65 on Monday night.

Sulaimon finished with a season-high 21 points and Rodney Hood added 14 for the Blue Devils (13-4, 2-2 Atlantic Coast Conference).

Debuting at their lowest ranking since the last time they fell out of the AP Top 25 in February 2007, they let an 11-point lead with 3½ minutes slip away before avoiding a third loss in four games.

Virginia — which was at or near 50 percent shooting in its last two games, including a 31-point rout of North Carolina State two nights earlier — struggled to hit anything early against a once-wobbly Duke defense while three times falling behind by 13 points.

They held the Blue Devils well below their ACC-leading average of 82.7 points per game and tightened things up by shooting 43.8 percent in the second half.

v. Virginia
(change from previous game)

Notes: With Parker and Hood held somewhat in check, and perhaps exhausted from carrying so much of the load through the first 16 games, Duke got a much needed lift from the bench in the form of Jefferson and Sulaimon.

In the middle Jefferson posted a career best +27 score thanks to a perfect shooting night from the field, a high rebounding total (15), and a handful of assists (2), blocks (1), and steals mixed in (2). Also of note was Jefferson's 2-of-3 from the free throw line - the final two being the game winning baskets.

On the wing, Duke got a +20 performance from Sulaimon who shot well (7-of-11 FG & 3-of-4 FT) and balanced his one turnover with a pair of assists and steals. The +20 was the sophomore guard's second highest output of the season, just behind the +25 he posted against Davidson in the season opener.

As for Parker and Hood, the duo combined for a +14, around 23 points below their combined efficiency score over the course of the season. Parker's +3 was a product of poor field goal percentage (he hit just 3-of-11 shots) and low rebounding and point totals (8 points and three rebounds). The 8 points on 11 FGAs really dipped the score.

Similar was the play of Quinn Cook who scored seven points on seven shots and had a negative assist to turnover ratio for the first time this season. Cook posted a +3, which is his lowest tally of the year.

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