There are some things you can't hide from:
Street-cleaning tickets, weirdos telling you that you've totally gotta see Breaking Bad or ESPN showing each and every ball that has moved in New York.
In the NBA, superstars can no longer hide behind simply their scoring average.
Today's league critic is advanced, overloaded with statistical material to spotlight any area of strength or weakness.
The player efficiency rating (PER) has become a measure of complete contribution. Scoring is important, but the efficiency rating takes into account shot attempts, rebounds and assists, too.
Admittedly, the efficiency rating doesn't reveal the true barometer of a player as a defender, though steals and blocks are included. Overall, this is more of an offensive ranking.
The NBA's formula is as follows: ((Points + Rebounds + Assists + Steals + Blocks) - ((Field Goals Att. - Field Goals Made) + (Free Throws Att. - Free Throws Made) + Turnovers)).
This list compiles the most and least efficient NBA stars, players who are a top piece for their franchise.
While the list is not based purely on the statistic itself, the selection of the included stars is a result of analysis of expectations vs.efficiency positioning.
