      I guess this is what causes the nagging doubt that I still have; although the inverse coefficient of variation idea is a good one, I wonder to what extent it really is measuring what we would call "consistency" as opposed to measuring who's got a large mean.

      Igor is correct that simply looking at standard deviation penalizes the Duncans and Malones who'll tend to have larger standard deviations than the bench scrubs of the league, who simply don't accumulate enough points or Manley credits (do we have to (TM) them like Tendex?) to have large standard deviations.

      But I wonder if the Consistency Score goes too far in the other direction, in terms of rewarding the Duncans and Shaqs with their large means.
