Efficiency Ratings: Clemson

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.


LATEST GAME
GREENSBORO, N.C. -- Rodney Hood hit two free throws with 3.8 seconds left to lift No. 7 Duke past Clemson 63-62 Friday night in the Atlantic Coast Conference quarterfinals. ACC rookie of the year Jabari Parker scored 18 points and Hood had 17 for the third-seeded Blue Devils (25-7).

They blew a 13-point lead with 12 minutes left before regrouping just in time to avoid joining No. 15 North Carolina and No. 11 Syracuse as ACC quarterfinal losers. Duke will play seventh-seeded North Carolina State in a semifinal Saturday.

Rod Hall scored 13 points to lead sixth-seeded Clemson (20-12), and his runner in the lane with 7.4 seconds left capped a late 15-5 run and gave the Tigers their only lead of the second half at 62-61.

After Hood's free throws, Hall made it deep into the lane before he was stripped by Tyler Thornton a moment before the buzzer sounded.


v. Clemson
(change from previous game)

  • Rodney Hood +13 (-7)
  • Jabari Parker +10 (-25)
  • Amile Jefferson +17 (—)
  • Quinn Cook +7 (-6)
  • Rasheed Sulaimon +12 (+1)
  • Tyler Thornton +9 (+9)
  • Matt Jones -1 (-)
  • Josh Hairston DNP (-)
  • Semi Ojeleye DNP (—)
  • Andre Dawkins -2 (-6)
  • Marshall Plumlee +2 (+1)

Notes: Rodney Hood told the media that Duke would have lost this game a month ago, and he's probably right. The reason Duke was able to win begins not at the free throw line where the team shot 16-of-18, but on the glass where Duke got a monster effort from Amile Jefferson to keep pace with a Tiger frontline that decimated Duke in Death Valley. Jefferson recorded 13 boards and six points in 34 minutes to finish with a team high +17.

Both Hood and Parker were well below their season averages in efficiency and in most other statistical categories after starting the game a combined 2-of-13 from the floor. Parker did finish with 18 points and six rebounds, while Hood added 17 and three. But the two combined to shoot just 11-of-30 on the night.

Marshall Plumlee's cameo appearance resulted in a +4 thanks to four boards.

Notes: With the end of the season approaching, there's not a lot of drama in the cumulative table. Andre Dawkins could catch Tyler Thornton, while Duke will likely hope that Jefferson and Cook stage a battle for the third spot. Simply put, Duke needs much more from Cook.
