I often get asked what NFL Draft guides I would recommend so I wanted to throw out a plug for my buddy Frank Coyle and Draft Insiders' Digest. For those who aren't familiar with Frank, he is an old-school draftnik who has been in the business for decades. Frank has consulted for teams and has a lot of contacts around the league. You may have heard him on the "DC" Podcast too!
There are a number of different packages available but you can get almost instant access to the online version of the 2012 NFL Draft Yearbook (PDF) for just $24.95. Frank actually sent me a copy and I will definitely vouch for it. So if you are looking for a guide to buy, give Frank a shot!
