SGP does account for this inherently because each category is being valued in context. The problem IMHO with SGP models is that they tend to overvalue the production needed to be the worst team in a category. People have added steps to the process in order to account for this but the systems end up being overly complicated scarcity models.
As far as the outliers are concerned, this is my main issue with standard deviation versus baseline. The zScore method tends to seriously undervalue the outliers, or from the other perspective baseline seriously overvalues them. Something has to give. They can't both be right.
Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
