This list is utter nonsense.  Some of these guys haven't thrown a pass in a real NFL game in years - but they rate higher than guys who have?  And there appear to be some people missing who will likely end up as a backup somewhere this year - such as Robert Griffin III or Matt McGloin.  There should also only be three groupings - guys that could probably start on other teams, guys whose history shows they are for emergency use only, and guys that lack sufficient live game action history/data to make any sort of judgement about.
