PPS (Points Per Shot): The number of points scored for each field goal attempt. PPR (Pure Point Rating): 100 x (Team Pace/League Pace) x [(Assists x 2/3)-Turnovers]/Minutes John Hollinger devised the PER efficiency metric. It is calculated by taking the average of a player's career PER to date (including this season), with some adjustments for age. If a player has not yet reached 30 years old, his or her per36 numbers are used in place of the full-season number. In other words, it's how many points you can expect to score on every shot you take. A perfect 100 means that you scored those points out of court goals as well as made all your free throw attempts. At 80%, it means that you scored more points than you allowed. The best basketball players in the world have very high PPS numbers. Think Kevin Durant, Stephen Curry, Russell Westbrook - they can all shoot the ball extremely well from beyond the arc! But even though they all share the same ability, they all have different PPS numbers because they take different amounts of shots per game. For example, Kevin Durant takes about 28% of his shots from downtown, while Russell Westbrook shoots over 40%. So if they both had the same amount of shots taken around the basket, then Durant would have a higher PPS number than Westbrook.
