Football Outsiders abuses the use of statistics and engages in data snooping (the "study" on running backs comes to mind) to make their points. They're far, far behind organizations and people who have lent credence to sports analytics, like Baseball Prospectus, Tom Tango, Pete Palmer, Bill James, etc.
I agree with you (although your comment sounds almost ranting) but you kinda have to mention them in any conversation about using data to understand football... even if it's not used properly.
