I didn't miss it, I just wasn't responding to it directly.
The field of journalism, with its mission, principles, strategies, and tactics, is rooted in its primary responsibility - to help maintain democracy by shining a light on the political process. The heart of journalism is to investigate what isn't being seen, to hold public officials as inherently untrustworthy. All journalists are educated with this as the foundation of their field, and shining a light on things that are behind the curtain is their impulse, their very reason for being. One could make a good argument that without a free press operating in this manner, we wouldn't have the freedom to have a patsfans.com.
Therefore, they are going to start with the assumption that the coach, as the authority figure, isn't being forthcoming, and will consistently push him and trying to pull back the curtain. We can blame them for being incompetent in the way they do it, and sports journalists are among the most incompetent in their field, hence all this controversy. But their belief that they play an essential role in ferreting out the truth is in their DNA.
Quite possibly true, and to some extent caused by homerism, which is the antithesis of journalism.
