The first thing you need in order to be successful is a plan. You need a clear and definitive identity of what you want your offense and defense to be.
Jerry has no clue. Drafting tight ends and not using them tells you all you need to know.
Changing offensive play callers, changing schemes, changing coordinators every year, means, he has no clue what he's doing.
I think we all know what Seattle is. I think we all know what type of team Denver is, or New England, or San Fran. But when you look at the Cowboys,
what type of team are we? What are we known for at the moment schematically speaking?
You can't just throw a coaching staff together and expect it to jell. There needs to be a clear boss, who should be Garrett. He's not.
You can't just throw any type of player out there to play in your scheme.
Seattle is not an offensive team that's interested in monster stats. They aren't feeding into the new aged high-powered sling it all over the field, type offenses. You don't
win with great QBs, you win with great QB play. Means, doesn't matter if the QB is great, he just has to play mistake free and efficient offensive football. Aikman was the king of this.
You don't have to play the hero roll to win a Super Bowl. Team play means, you do your part in moving the ball efficiently, the special teams has to do their part, and the defense has
to cause mistakes for the offense.
This philosophy is the grounds for not just a super bowl victory, but a dynasty.
