Yeah, I don't know how the pre-ranking determines players.  Cam Newton, Aaron Rodgers, Andrew Luck, and Russell Wilson were all ahead of Brees in QB pre-rank so even though Brees is a "big name", he was 5th.  Is it on the previous season's stats?  I didn't follow everyone's stats too closely, but I thought Brees had a good year.  I guess the other four were better though?  Probably the same with the RBs... although I don't know how draft picks get placed in the pre-ranking since they didn't have a "previous year" in the NFL.
