Grading the draft

The NFL draft was this weekend. You can find no shortage of the people willing to rate every team in the draft. I think this is a little silly. None of the guys that rate the draft ever say anything about how well their grades from the year before hold up. Right now I want to see ratings for the 2005, 2006, and 2007 drafts. That would make me more confident that the 2008 ratings actually mean something. To me none of this means anything until they put on the pads in the fall.
