Efficiency Ratings: Virginia

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

Latest Game:

The Blue Devils beat the seventh-ranked Cavaliers 63-62 on Saturday on that shot Allen banked in at the horn.

Freshman Brandon Ingram scored 25 points while Allen finished with 15 for the Blue Devils (19-6, 8-4), who won their fourth straight and kept the Cavaliers winless at Cameron Indoor Stadium since 1995.

Duke called a timeout with 6 seconds left, with coach Mike Krzyzewski later saying he instructed Allen: "You go. See what's there."

Allen inbounded the ball to Marshall Plumlee, who handed it right back to the sophomore guard.

"Get the ball in Grayson's hands, don't do anything stupid, try to make a read," Plumlee said. "I did my part. Grayson did the hard part."

Allen drove the left side of the lane on defender Marial Shayok, then went airborne while flinging up a one-handed shot that kissed off the glass and went through at the buzzer.

Matt Jones finished with 14 points and Plumlee had 10 rebounds for the Blue Devils. After failing to beat a Top 25 opponent for the first three months of the season, they have now knocked off two in six days after beating No. 13 Louisville on Monday night.

Notes: Both Ingram and Allen had big nights which has become the norm throughout the season, but the unsung hero on this night was Matt Jones. The junior hadn’t put together a game with an efficiency score over eight in more than a month, but did so against Virginia. Jones hit five of six shots to finish with 14 points and two rebounds on the afternoon.
