He's saying you can't attribute these comments to media because that's not their source.
These bits are taken from scouts, coaches, GMs, etc. People that work in the NFL, not sportswriters.
Well, I took the OP's word and didn't read the article (till someone pointed it out to me). LOL
However, after reading it. I still don't know if it's not their comments; the same way they had all those "anonymous sources", pre-draft on Cam that was easily disproved and obviously lies.
I don't take them/that seriously.
