Translating Euroleague Stats

Saving this note from Stat man John Hollinger for future reference:

"There's a very predictable relationship between a player's stats in Europe and what they'll be in the NBA, one that shows surprisingly little variation between players. Those who make the jump from the Euroleague (the highest level of European basketball) to the NBA can expect the following:

• their scoring rate to decrease by 25 percent;
• their rebound rate to increase by 18 percent (there are more missed shots to grab over here);
• their assist rate to increase by 31 percent (their scorers are stingy on assists);
• their shooting percentage to drop by 12 percent; and
• overall, their PER drops by 30 percent."
