I'm going to go out on a limb and suggest that most fans, homers or no, aren't going to consider changing opinions all over the place over the course of a single offseason before a single game that counts has been played to be a good thing.
I'm probably one of the bigger 'homers' on the board, and I can tell you, from my experience here, the issue isn't so much posters being unwilling to say anything critical of the team. I've been very critical this offseason, for example, of the play of the defensive secondary (Safeties) last season. Of our turnovers in general. Of our lack of takeaways. Of our old defensive coordinator (Ryan, not Kiffin
). Critical of the team's handling of certain situations--most notably the announcement of the play calling duty changes. I'm was concerned about the Kiffin hire, and I'm still concerned about our ability to stop the run and the read-option in the new defense. None of that means much, though, when you say it to a group of posters who are so frustrated with a lack of postseason success they want to believe literally everything is wrong with the organization. They hear the criticism and shake their heads in agreement, then try to extend it to Tony Romo. Or Jason Garrett, or complain about how often we run the ball, or some other issue of little-import, and that's where the rub comes in. It's not that homers don't see problems. It's that they don't tend to agree that every single thing is a problem. Spread out over enough people, this means you're going to have a homer argue against almost every single type of criticism.
But there are plenty of discussions I just don't engage in much because I say my critical piece early and move on to another topic. To me, there's little point in making the same criticism hundreds of times. It's enough to get it on the record and then move on until and unless that specific criticism becomes news or is addressed by the team.
And I don't have a particular problem with how the current management of the team has stocked this roster, for whatever that's worth. The business end of the organization is in great shape. If I have a problem with Jerry Jones its in that he's an embarrassing figurehead when he gives interviews drunk. He (reportedly) allows players to go to him directly and around the HC, and he has a tendency to tip his hand when he's trying to be cryptic and everybody in the world knows exactly what he's trying not to say. These are all criticisms I've had about the guy for years, though, and not something that just occurred to me in camp one day. All in all, I'm pretty consistent and stubborn in my outlook towards the team.
