It was a woman that wrote that article, Tony.
I always blamed the Jerry/Jimmy split up on Jerry, for obvious reasons. Mainly that Jerry wanted to tell him how to coach and run the team the way he saw fit, and Jimmy having none of it.
I never gave much thought to the marketing side influencing why Jerry can't make prudent football decisions, but it makes good sense. As Jerryworld grows, the Cowboys continue to sag.
He can't hire a real coach because a real coach wouldn't work for him.
It really does suck, bad. I'd just like to see the Cowboys competitive so I could take greater joy in the getting beat.
