I hope you aren't this stubborn with your wife
You guys aren't thinking rationally about it. No coach who is coming off a 12-4 division win season is going to be fired when he loses his starting QB for all but 3 games. It's not happening, and it shouldn't happen.
That being said, don't take that to mean I'm happy with the coaching performance. This team came into the season with contender expectations and it's clear that they just aren't on that level at all. Even with Romo, they'd be winning this division by default cause it sucks so bad, but they aren't on the same level as the truly good teams.
The OL has regressed, the defensive line has completely underperformed, they completely blew their RB evaluation and they have no WR to take pressure off Dez.
