How accurate are inside sources?

[BeastsoftheNFCeast]

This is my first draft where i have been a true football fan who is knowledgeable, has followed the coverage, and knows whats up. Therefore I dont know how accurate all these inside sources are. Is Detroit really sold on Gaines Adams, is Cleveland really sold on Brady Quinn, ect... Should i beleive reporters who write that an inside source says that their team is going to pick somebody, should i take it with a grain of salt, or should i take it into consideration but not take it seriously. Basically what im asking is how reliable have inside sources been in the past.
