So Garrett shows the text message to a reporter. This doesn't make him any better. Actually, it just proves once and for all Garrett losing the team and doesn't have the balls to show some leadership in righting this ship.
In fact, Garrett talks about integrity alot. But showing this text to a reporter rather than keeping it behind closed doors, just show his is integrity lack of.
To a degree, that's true, but its how you use the media.
McCarthy is going to have to use the media as a tool in order to impose his will over Jerry if he is going to be a successful HC here.
If McCarthy is destined to become the next great HC of the Cowboys, he will have to know the art of controlling the media in certain situations when behind closed doors, when
he is in disagreement with Jerry and how Jerry wants his show run.
If he cant or fails to do this, he becomes yet another puppet just like Garrett.
