From the comments section of the post, Lance's explanation regarding Patterson falling out of the first round:
League source who has given me incredibly accurate info that has appeared in this blog for 5 years told me Patterson could very well fall out of the first round. When he says something like that, I listen. He was the one telling me to put Bruce Irvin in the 1st round when nobody else had that last year.
My thoughts: No one in the media is in the room during player interviews, and they don't have much visibility to some important aspects until after the draft. If you have a reliable source who does have visibility, then that information has a lot of influence.
