Weird how a lot of people always run into or over hear NFL scouts on this board
I share your skepticism. This may be legitimate. Often it is not. And the trend is hardly restricted to sports forums. I've seen it on true crime sites and political sites and elsewhere. The person wants to give his own opinion a boost of legitimacy so he paints and shines it via sourcing from an anonymous authority. The vehicle seldom varies. It's always a friend who he happened to run into and suddenly this guy shares virtually every specialized knowledge and opinion, word for word. Quite remarkable.
When it is legitimate normally there are more direct quotes instead of summaries, and more of the quotes will include angles and ideas that are atypical, since an outsider won't be seeing everything from the same perspective that we do. Wow type of stuff. Didn't think of that. Plus the specialist generally won't be familiar with everybody and everything, since his duties include dozens of other schools, etc. He will be confident enough to concede he's not an authority on everybody.
This is a low post OP. I apologize if it's legit. I have no opinion either way. But I've caught several posters attempting this elsewhere. Handicapper's instincts. One guy ran away and never posted again.
