There is another website that does a great job with weighing stats - www.footballoutsiders.com
Aaron Schatz - formerly of the Lycos 50 - does the website very well - very informative board. There is a "New England" slant there - but the rest of the league is highly representitive.
If you like Will Carroll's Baseball Prospectus - you will like Aaron's Website.
Also - take the time reading the into to FO - you will get the website very well after that.
