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.

Jason Blossomgame had career highs of 14 points and 14 rebounds, plus hit two critical 3-pointers to move the Tigers in front for a 72-59 win Saturday, sending the Blue Devils to their first 1-2 Atlantic Coast Conference start in seven years.

Blossomgame was one of the Tigers' most highly regarded recruits two years ago, but missed his freshman season after breaking a leg. He had a second surgery on that this summer and the 6-foot-7 freshman has taken his time this season finding his way.

"This is big day for me, my breakout game," Blossomgame said. "I've had a rough start, but I'm trying to get back into the flow of things."

His big shots helped turn Duke's 10-point first-half lead into a Clemson runaway.

Blossomgame's 3-pointer with 9:27 left put the Tigers (11-4, 2-1 ACC) out front, 52-50, for the first time since the game's early moments. With the game tied at 54-all moments later, Blossomgame struck from left corner to give Clemson the lead for good.

(change from previous game)

Notes: Parker seemed to be out of his mini-slump early on. The freshman raced out to 10 first half points and finished with a strong line of 15 points and seven rebounds, though his shot was still off (5-of-13). While the team result was certainly less than ideal, Duke has to be somewhat encouraged to see their prized freshman showing signs of breaking out of a tough stretch.

Meanwhile, Rodney Hood continued his strong scoring spree by adding another 20 points. Despite the high scoring output, Hood's rating was just a +10 - down 21 points from last game. Why? Because there was virtually nothing more than shot attempts and points to factor into the formula. The lefty southpaw logged just one rebound, no assists, no blocks, and no steals.

In the middle Duke got a +12 rating from Amile Jefferson who battled for seven points and six rebounds in 27 minutes while backup Josh Hairston logged a +2 via his two rebounds in eight minutes.

Starting point guard Quinn Cook's offense was as inefficient as it has been all season behind 3-of-14 shooting. However, Cook did manage to overcome the 11 missed shots to post a +9 thanks to a 7-to-1 assist-to-turnover ratio.

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

Tracking the most and least efficient performances by player

  • Rodney Hood +32/+3
  • Jabari Parker +30/-1
  • Amile Jefferson +17/+1
  • Quinn Cook +31/+8
  • Rasheed Sulaimon +25/-2
  • Tyler Thornton +15/+0
  • Matt Jones +12/-3
  • Josh Hairston +8/-1
  • Semi Ojeleye +16/-1
  • Andre Dawkins +23/-3
  • Marshall Plumlee +7/-1

Notes: While Parker and Hood have carried the load for most of the season, it seems that Duke simply cannot function at the highest levels when either of the two aren't producing efficient games along with Quinn Cook. That's to be expected, and the coaching staff has quite a challenge going forward in coaxing more production out of the secondary players.
