It really doesn't matter who we bring in or if we bring in anyone at all, until Jerry steps down as the GM and relinquishes control of his "toy" to his son, all the HCs will be hampered by the same issues.
We've had a hands-off coach in Switzer (won with Jimmy's team but not after that). We've had a smart coach in Gailey, was stuck with assistants that he didn't get to select, plus he wasn't all that afterall. We've had the home-grown, company-man in Campo, he flat out sucked. We've had the tough, no-nonsense HC in Parcells, got rid of some riff-raff but no playoff wins. We've had the softer, family approach of Wade Phillips and had some early success but have still not won a playoff game.
The one constant in all of this is Jerry Jones. There is no discipline, even under Parcells, because the players KNOW who really runs the team and makes all the final decisions, and it ISN'T the HC.
Jimmy had control over the players, and it worked, but at the end of the day, Jerry found that Jimmy got all the credit and he didn't like that.
Jerry Jones is a billionaire fan who bought his own team for the express purpose of buying his way into the game. He wants to hang out with the players, stand in front of the cameras, be the face of the team (yech), make personnel moves as if this were a video game, and more than anything else, be seen as the guy who made it all happen.
This past off-season we finally saw him back off some and allow others to make the personnel decisions, or at least many of them. We had a good draft and avoided dumb moves in FA. We drafted and signed good, solid players.
Keith Brooking was a great signing! Sensabaugh was a solid addition. Letting Owens walk was a smart move. Olshansky was a nice replacement for Canty. None of them broke the bank and all of the guys we brought in are good players.
I think this team is moving in the right direction MOSTLY because Jerry has been less involved. The more he backs off the better this team is going to be, regardless of WHO the HC is. Obviously the better the HC the better the team will be, but until Jerry takes his hands off the team it won't matter who the HC is, we cannot achieve our goals with him in the way.
