Here is the thing boss, it doesn't take a genius to realize that Garrett and Jones had deal worked out before the season started with a handshake that unless things got turned around he was going to have to go in a new direction. Think about it for a second, if you're Jason Garrett, you have no problem accepting this because you understand you've had more than enough time to coach the team to the super bowl.
At this point, Jason knows he is gone, so does the team, and everyone involved in the organization. If you watch Jason's demeanor over on the sidelines and during press conferences it's very obvious he is humiliated and embarrassed because he knows he failed. Make no mistake about it, things are uncomfortable between Jerry and Jason and this 100% why the team has lost it's purpose and edge. There is also no doubt this will continue through the rest of the season as everything plays out.
Lets forget Jerry and his meddling here for a second and see things truly for what they are. Jason failed, he couldn't get it done, his process failed, his message is stale, and he has proven to be a middle of the road coach with zero upside. I agree with you in the sense that this has been incredibly difficult to take as a fan, knowing this wink and a handshake Garrett and Jerry have had all along.
