Well, there's always going to be a certain error associated with projections, which we won't really be able to eliminate; though I don't understand some of your comments. No way to predict the outliers? This is a truer statement for some stats more that others, but declaring that Pierre is likely to be a SB-outlier can certainly be made from a sound statistical foundation. And individual predictions do have a fair amount of use, though their confidence intervals are perhaps larger than people realize. The suggestion that it's better to have average performers in each category rather than having certain categories covered by few sources (as is often done with SB) is true (as it's just simple statistics), but it's not really because we don't know who the outliers might be. (We're just taking on more risk, in the form of larger confidence intervals, by relying on the performance of those we expect to be outliers.)
My suggestion was not that it's better to have average performers. My comment was suggesting that fantasy players focus far too much on individual player projections, when what they should focus on is the average prediction (and the variance of that prediction, though that's another issue) of the set of players they choose.
