As far as I know, -poisson- is for skewed distributions, and salary distribution in general often fulfills this requirement, but salary of NBA players might show a different distribution. The distribution can be checked, e.g. with the command -histogram salary- (for more information type -help histogram-). Andy, I would compare the assumptions and requirements of different estimation strategies (OLS, poisson) and find out which fits better with the data. I would also check which estimations strategies are used by similar papers, and why. Apart from -poisson- and -regress-, I cannot think of any at the moment that have to be considered for your salary-estimations. However, if there was something like a "minimum wage" for NBA players, i.e. salary is censored, -tobit- would be an alternative.
