Listen .. there is not an owner in the league that it unable to hire or fire any coach or player that he wants to hire or fire.
The media makes a big deal out of it because it is Jerry Jones and the fans inhale the media's propaganda and fall right into their trap with it.
During the Jason Garrett as head coach press conference earlier, the media spent half their questions discussing the "who has say so over personnel" and each time Jerry answered it, they asked it again trying to trap him into giving them a sound bite or headline.
Jason Garrett is a smart guy and there is no way someone with his background would be forced to play any specific player or retain any specific coach. Garrett is not a Campo, Phillips, Gailey, etc. coach who is just happy to have a job. Garrett knows he is good at what he does and knows that if Jerry won't let him make decisions that another team out there will.
The biggest difference with Jason Garrett though is Jerry trusts him and his ability to make decisions and assess players and coaches unlike what he had with Campo, Phillis, etc. A lot of that is because of Garrett's background as a player under several good coaches and exposure to his father's scouting background for most of his life.
It's time for the media and fans to move on from the "who's in charge" phase and focus more on the "how do we right this ship" phase.
