I'm trying to figure out a similar sort of thing, but my system is a little different.

I take the pool of players that I'm sure will be drafted split them by D F and take all of their totals in the categories and find and average value. Then divide and determine their points and other totals compared to the averages.

And I get the ratio of a category compared to the average, then I sum them all and divide by the total number of categories.

Obviously it's far from being a super super accurate way to rank players, but it gives me a number that I know at least accounts for all my categories equally. In combination with other tools and rankings it gives me a usable list.

Edit-When I determine the ratio between their total in a category and the average which I've found limits the skewing of their number by performing very well in only one category. All the other categories where they are under the mean is assigned a negative decimal (1-ratio discussed earlier) and if its a flat 0 in a category they receive a -1.

I've found this system of assigning numbers keeps category specialists from having a value that's too high.

And I believe comparing them to the "average" player will provide far more information.

And since it was mentioned, I thought this up after watching moneyball.
