Efficiency Ratings: Notre Dame

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

Latest Game:

Notre Dame earned its first berth in a conference title game by beating No. 2 Duke 74-64 on Friday night in an ACC semifinal.

Bonzie Colson scored 17 points and Demetrius Jackson added 15 points and Jerian Grant had 13 for the third-seeded Fighting Irish (28-5). They shot 50 percent, led by 17 and held off the Blue Devils' comeback attempt to beat them for the second time this season.

Jahlil Okafor had 28 points on 13-of-18 shooting for the second-seeded but slow-starting Blue Devils (29-4), who had their 12-game winning streak snapped by the last team to beat them. Notre Dame won 77-73 on Jan. 28.

"Really, for about the first 24 minutes, I'm not sure -- I don't know who we were coaching tonight," coach Mike Krzyzewski said. "We weren't talking, we weren't doing anything. We weren't following instructions. It was like an out-of-body experience."

Tyus Jones pulled Duke to 68-64 with a 3-pointer with about 3 minutes left.

The Blue Devils didn't score again.


vs. NOTRE DAME

(change from previous game)
  • Jahlil Okafor +27 (+15)
  • Justise Winslow +21 (+5)
  • Tyus Jones +7 (-2)
  • Quinn Cook +0 (-16)
  • Amile Jefferson +6 (+2)
  • Grayson Allen +1 (-12)
  • Matt Jones +2 (-7)
  • Marshall Plumlee +3 (-16)



Notes: While Okafor’s stat line looks great (28 points, 8 rebounds on 13-of-18 shooting from the field), it was drug down by the big man’s inefficient free throw shooting (again). Duke’s center got to the line eight times, and it probably should have been more, but made just two those eight attempts, pulling his score below 30 and, ultimately, preventing Duke from getting back into the game in the second half. The two biggest misses came with Duke down five and having a chance to make it a one possession game.

Classmate Justise Winslow had a poor first half, and was benched to begin the second. However, the Houston native went to work upon entering the game after intermission and finished with a +21 thanks to 5-of-8 shooting, 11 rebounds, 11 points, and three assists.

Where Duke was ultimately let down, however, was in the backcourt as the duo of Tyus Jones and Quinn Cook struggled shooting the ball (combined 6-of-25 from the field), and posted eight assists against seven turnovers. It resulted in Cook’s work score of the season (+0) and one of Jones’ lower scores (+7).

SEASON HIGH/LOW PERFORMANCES


Tracking the most and least efficient performances by player
  • Jahlil Okafor 37 / 7
  • Amile Jefferson 30 / -1
  • Quinn Cook 27 / 0
  • Tyus Jones 34 / 1
  • Grayson Allen 28 / -3
  • Justise Winslow 29 / -5
  • Marshall Plumlee 19 / 0
  • Matt Jones 17 / -2


Notes:

- Jefferson and Plumlee remain two of Duke’s more efficient players per minutes, but neither has been able to gain much traction down the stretch in terms of extended playing time.

- Cook suffered through his worst game of the season, and ends his ACC career with zero conference titles of any kind. It’s the first time since 1985 that a senior class hasn’t won the league in some variety.
