Just so we are clear...He can't do that and not be penalized by the team. It sets a horrible precedent for your team.
My take is that he is one of those guys who doesn't get the soft-as-baby-shit mentality Garrett and many Cowboy players have. I get being so mad at that pussy mentality that you lose your temper. He needs to be reigned way in, but he's not wrong for being pissed. The country club atmosphere from Jerry and the Tony Robbins impostor at head coach doesn't mesh with guys like Hardy, Charles Haley, Ray Lewis, Junior Seau, etc. who play pissed off.
You can't have a bunch of outstanding citizen, nice guys on defense. You have to have some thugs. The tough job is getting those guys to buy in enough to show some self-control. Garrett is incapable of that and Jerry is an enabler.
