Think realistically about this.
Who's involved in decision to fire Mike Riley, and if he's fired, to replace him?
How big is that room?
And what kind of dollar figures are we talking about in that process - how many millions?
Then ask yourself - what kind of person is admitted into that room, where millions of dollars are at stake? People who keep their mouth shut or people who talk a lot?
When you arrive at the latter choice, ask yourself how Adam Rittenberg, who hasn't set foot in Lincoln in weeks and who does not have the confidence of anyone in that room, get information on what decisions are being made in that room?
And when you realize he doesn't have that confidence and they won't tell him anything, and nor will any agent/agent's staff, or any coach, or their families, or anyone involved, ask yourself where Rittenberg is getting that information? Or random posters on an RSS?
tl;dr - nobody knows what's going on - not RSS posters, not local or national media types, nobody. Anyone who does isn't talking, because talking means termination.
