It is management to coaching all the way down to talent and depth. Starts at the top and rolls downhill. Only a new head coach with skins on the wall has a chance to turn this around. I don't see a new or young HC dealing with this atmosphere.
I don't want Gruden much either, but he just might have the best chance for success IMO.
THE PROBLEM IS, AND WILL ALWAYS BE, JERRY JONES. "A head coach with skins on the wall" has no chance of turning this around as long as he does not have final say over who he keeps on his roster. "Group decisions" might work for the draft room, but once a player is on the team, he must answer to the coach, and the coach only. There is no "fear" in the players on this team in their interaction with Garrett. Let's look at the Ratliff/Jones set-to in the locker room last year: is there any chance Garrett could have stepped up and told Ratliff to clean out his locker and hit the street? He should have, he might have wanted to, we'll never know about that, but in my opinion, Garrett lacks the authority within the organization to do that. Jerry Jones thinks he can schmooze, get chummy with, and high-five the players into contributing to the team effort. The players WANT to succeed. They WANT to win, but the unit itself is too disfunctional at the top to bind the players into an effective force.
As an analogy from Army, I would put it this way:
How it is: Jerry Jones is the Battalion Commander, Jason Garrett is the S-3, and there is no XO.
For those who have no idea what I mean, the Battalion Commander (usually a Lt. Colonel) is the highest ranking officer in the Battalion. He has ultimate and total authority over who he assigns to what duty, who he fires, and how his unit is run. And, he is ultimately responsible for everything his unit does, or fails to do. The S-3 (usually a Major) is the plan and scheme guy for the unit. He plans every move the Commander wants to make and is largely responsible for disseminating that information to the rest of the unit. He also coordinates the unit training. He is usually respected but seldom feared. The Executive Officer (XO) (usually a Major) is the most influential officer in the battalion. He does not have firing authority, but he is widely feared because everybody knows that he is the Commander's enforcer. He snaps the whip and keeps everybody on the staff focused and on the same page.
How it should be: Jason Garrett should be the Commander, Bill Callahan should be the S-3, and Garrett should have a strong Assistant Head Coach to be the XO. Jerry Jones should be the visiting congressman who just comes by to shake hands, back slap, and to see how the tax dollars are being spent.
The analogies between an NFL team and military unit are endless. It is combat where casualties are something that must be expected, and the mission must still be accomplished. To achieve the mission, the unit must have discipline, cohesion, morale, trust in each other, and they must be led by a commander. If the command structure is flawed, the soldiers will not trust their leadership, they will not trust each other, they will hesitate when they should be executing, they will fracture into self-preservation mode, they will view the mission as unattainable, and will thereby deduce that their efforts are wasted. When that happens they will go through the motions because the structure still has authority over them, but it will be effort in appearance only. And this kind of unit will NEVER accomplish a difficult mission.
The last real commander this unit had was Jimmy Johnson. Parcells could have been, but he was too old to keep fighting an uphill battle.
