What's the difference?

The Player Efficiency Rating (PER) is a rating of a player's per-minute productivity.
To generate it, I created formulas -- which I outlined in tortuous detail in the book "Pro Basketball Forecast" -- that return a value for each of a player's accomplishments. That includes positive accomplishments, such as field goals, free throws, 3-pointers, assists, rebounds, blocks and steals, and negative ones, such as missed shots, turnovers and personal fouls.
Two important things to remember about PER is that it's per-minute and pace-adjusted.
It's a per-minute measure because that allows us to compare, say, T.J. Ford to Jose Calderon, even though there is a disparity in the minutes they played.
I also adjust each player's rating for his team's pace, so that players on a slow-paced team like Detroit aren't penalized just because their team's games have fewer possessions than those of a fast-paced team such as Golden State.
Bear in mind that this rating is not the final, once-and-for-all answer for a player's accomplishments during the season. This is especially true for players -- such as Bruce Bowen and Jason Collins -- who are defensive specialists but don't get many blocks or steals.
What PER can do, however, is summarize a player's statistical accomplishments in a single number. That allows us to unify the disparate data on each player that we try to track in our heads (e.g., Corey Maggette: free-throw machine, good rebounder, decent shooter, poor passer, etc.) so that we can move on to evaluating what might be missing from the stats.
I set the league average in PER to 15.00 every season.
Among players who played at least 500 minutes in 2006-07, the highest rating was Dwyane Wade's 29.04. The lowest was Collins's 3.02.
