NBA coaches and executives have a statistic that illustrates the overall efficiency of a player, with the EFF ranking taking into consideration offensive contributions to calculate a player's overall efficiency during the game.
The list will surprise some fans as they might not find their favourite players in the top five; aside from just scoring and rebounding in high numbers, the player must have a high field goal percentage to upgrade his efficiency numbers.
20) ANDRE DRUMMOND (Detroit Pistons) - EFF 22.9Playing at center, Drummond is averaging 14.9 points per games (PPG) and 13.6 rebounds per game (RPG) this season. When Andre dominates the Pistons are a tough team to beat, though the team has been struggling at .500 for the season. 19) KYLE LOWRY - (Toronto Raptors) - EFF 23.3 The Toronto Raptors are 17-7 this season and are contenders in the Eastern Conference. Lowry is averaging 21.3 PPG and 7.3 assists per game, as well as shooting a solid 43.3% from 3PT. Playing with Demar Derozan on the wing gives Toronto a strong one-two punch. 18) BLAKE GRIFFIN - (Los Angeles Clippers) - EFF 23.7 The Clippers are sitting at 18-7 and beat the defending NBA champions Cavaliers soundly on the road. Griffin is averaging 20.7 PPG and 9 RPG. The power forward has also become more efficient from the FT line at 74.7%. 17) DEMAR DEROZAN - (Toronto Raptors) - EFF 23.8 The high-flying guard has been averaging ridiculous numbers this season. His 27.8 PPG are winning Toronto many games.At the beginning of the season Derozan averaged 30 points or more in his first five games, the feat has not been accomplished since Michael Jordan in the 1986-87 season. 16) KEVIN LOVE - (Cleveland Cavaliers) - EFF 24.1 Playing with Lebron James will definitely help your game. The 17-5 Cavaliers depend on Love's interior presence as well as his outside shooting; he is averaging a double-double this season at 21.7 PPG and 10.3 RPG. =14) KAWHI LEONARD - (San Antonio Spurs) - EFF 24.4 The Spurs have an all-round star in Leonard; the forward can do it all from shooting to lock-down defense. He has been recording 24.7 PPG and six rebounds, to add to his efficiency he shoots 91.4% from the FT line. =14) KARL ANTHONY TOWNS - (Minnesota Timberwolves) - EFF 24.4 Last season's rookie of the year made an impression on the NBA; Towns is an all-round center who can shoot and rebound while stretching the floor for his team-mates. He is averaging a double double for the T-wolves despite the team's poor record of 6-18. 13) JOHN WALL - (Washington Wizards) - EFF 24.5 The star point guard is putting up good numbers this season: 23.6 PPG 9.6 APG and 4.3 RPG. But the Wizards are underachieving so far, holding a 9-14 record in the Eastern Conference, which is less competitive than their counterparts in the west. 12) HASSAN WHITESIDE - (Miami Heat) - EFF 24.9 At 7 feet-tall and 265lbs Whiteside is a force to be reckoned with in the center position. The big man is collecting 14.3 rebounds a game and scoring 17.3 PPG while patrolling the paint on defense with 2.4 blocks per game. =10) DAMIAN LILLARD - (Portland Trail Blazers) EFF 25.2 One of the top scorers in the NBA and an All-Star, Lillard can score on any team with ease. The hybrid point guard is averaging 27.8 PPG and 5.6 APG, but the team is not performing well with a 14-12 record so far. =10) STEPHEN CURRY - (Golden State Warriors) - EFF 25.2 The back to-back MVP is having another great season, with his team sitting atop the Western Conference at 21-4. Even with the presence of Kevin Durant on the roster, which means less shots from time to time,"Chef Curry" is still averaging 25.4 PPG with 5.8 assists. 9) CHRIS PAUL - (Los Angeles Clippers) - EFF 25.8 The multi-faceted point guard is the Clippers coach on the court, orchestrating the offense and distributing the ball around. Paul has 9.4 assists per game and is logging 17.8 PPG, as well as rarely turning over the ball. He achieved a historic feat against the Pelicans on Dec. 11 (??) #360fans on Twitter or getting in touch via Facebook.
