The Most and Least Efficient Players in the 2012-13 NBA Season
Frank Victores-USA TODAY Sports
Who is the league's most efficient player and who is the least efficient?

No one runs three miles to burn 15 calories.

It’s all about efficiency. We want maximum results with minimal effort.

The NBA values players who can achieve the most results with the least waste. Waste means a high number of opportunities that don't produce results.

Statisticians have found a method to help determine a player’s effectiveness: the NBA efficiency stats.

Yup, it's nerd-alert time. Let's dig into the numbers.

First, we need to establish what it all means. The NBA computes the numbers with the following formula:((Points + Rebounds + Assists + Steals + Blocks) - ((Field Goals Att. - Field Goals Made) + (Free Throws Att. - Free Throws Made) + Turnovers)).

For instance, if the "purple player's'' line was 31 points (14-for-25 and 3-for-6 FT), 8 rebounds, 4 assists, 2 steals, 1 block, 3 turnovers, then that formula (46) – (11+6) would create for an overall efficiency rating of +29.

If the "red player's'' line went for 20 points (8-for-10 and 2-for-2 FT), 7 rebounds, 5 assists, 1 steal, 1 block, 0 turnovers, then the math of 34 – (2+0) would create an overall efficiency rating of +32.

The NBA’s efficiency stat concludes that the “red player” actually had a more efficient game and is more valuable to the team.

The idea is that if a team has a lineup of more efficient players, the better that team will perform. Teams that carry less efficient players will struggle.

Furthermore, when combined with the per 48-minute stat (EFF48M), an additional gauge of a player despite opportunity given by a coach, is put on display.

Let's take a look at a lineup of the league's most efficient players and the league's least efficient players.
