If I'm not mistaken you could basically do this through Yahoo now. While it won't give you the actual roto points in a h2h league they will now give you the cumulative totals for each category (ie this team has 820 runs for the year, this team has 816 runs for the year, etc). Just dump that into a spreadsheet, use the rank function and voila, roto scores.

grows like ivy on the vine
then dies in the fall
