He is also a business idiot if he doesnt realize the Cowboys doing WELL would make him more PROFIT.
People don't speak on this enough. They say Jerry is a great owner because he makes a ton of money. The Dallas Cowboys were already a well established franchise with extreme popularity and being polarized nationwide before he got there. How some tell the story, Jerry is some underdog hero story who took some lowly team like the Lions and built them into some superpower. Far from the truth.
I give Jerry credit for two moves. Firing Landry (it needed to be done) and hiring Jimmy. That's it. Jimmy took over the reigns and built that team to what it was. Hired a great staff. Jerry stayed out the way. But after the 2 rings, Jerry's ego saw no one mentioned him. He hated that and he undid everything Jimmy built. So Jerry giveth and Jerry taketh away.
I don't give Jerry any real credit for making a ton of money with the Cowboys. The NFL is a cash cow and prints its own money. No team loses money, ever. The Cowboys brand was huge before he got there and will be huge long after he is gone.
Great businessmen make decisions for the best of their company as a whole and put them in the best chance to succeed. Jerry doesn't. Jerry only makes decisions that benefit him. And the fans suffer because of it.
