These are the sites that Draftboy is involved with and promoted recently. Walter Football added them to its 2012 database. None from the Patriots draft site yet, but the Jets and Dolphin draft sites have Buffalo drafting 3rd in 2012, versus (what I presume is) Draftboy's mock which has Buffalo drafting ninth overall. Obviously, oour AFC East opponents don't have a very high opinion of Buffalo's rebuilding plans and progress so far.
