By the way, they did a study on 82games about the value of a potential assist where they charted things like shot attempts (made and missed), times fouled shooting and turnovers from "potential assists":
http://www.82games.com/assisted.htm Here are a few snippets from the article:
_____________________
"a shot that comes by virtue of an "assist worthy" pass had an over 8% better chance of going in for the sample we looked at"
_____________________
"The value of the potential assist could also be stated in this fashion:
+.25 points for every Close Shot
+.19 points for Two-Point Jump Shots
+.14 points per Dunk Shot
+.10 points per Three-Pointer
...or +.16 points on average"
_______________________
"If you conjure up a simple points per 100 possessions (omitting the offensive rebound implications), you find it looks like this:
110.4 - w/Potential Assist
81.9 - not assisted "
_________________________
"Throw out the turnovers then and just look at a points per shot number and it's:
1.17 - w/Potential Assist
1.04 - not assisted"
