Martínez, J. A. (2012). Factors determining production (FDP) in basketball. Economic & Business Letters, 1 (1), 21-29.
You may download the paper here:
As you may read in the paper, this is a new form of consider productivity of players in baskeball, by separating points (production) from factors determining production.
Comments are welcome!
In addition I have made some additional computations with the recently finished 2012 season.

Please be cautios. To compare players from different teams you may suppose that conditions of the game are the same among disparate players and teams, and this is a somewhat dangerous assumption... But if you want to "dream" with that ideal context, you can see that, for example, that Lebron did better than Kobe and Durant...
