He's right but the problem is they're not taking a hit in the wallet so there really isn't much incentive for them to change their ways. Sure winning the Super Bowl is nice but didn't the last Forbes list have the Cowboys as the most valuable sports franchise in the world. So even though over the past 20 years this team has only achieved marginal on-field success, the Joneses are making money hand over fist.
Also, when you look and listen to Stephen Jones you realize that he's going to have a similar philosophy as his pops. I.e. "Keep it in the family. Nepotism trumps credentials." Then you look at the young kid (Shy or whatever his name is) who is always hanging out in the draft room and at organizational functions, and you realize that 30 years from now he'll be running the show. And everything that he's learned, he learned it from Jerry. So he'll probably grow up thinking Jerry's way is the "right way".
And once Shy marries and has kids of his own he'll likely pass down the same flawed ownership/management style to his children; and so forth and so on.
It's just a vicious cycle that I see no end to. Which is why I've become increasingly apathetic towards the Cowboys. I don't buy merchandise anymore, I rarely read Cowboys related articles, etc. If I hear about a key player suffering an injury I just shrug and move along. Whereas in the past I'd be wringing my hands and over-analyzing the impact of playing w/o said player(s). I've just grown tired of trying to fool myself that this year or next year will somehow be different.
And no this isn't a case of me just being over-saturated with the vast amount of sports information available at our fingertips. I read multiple articles a day on the Atlanta Braves, OKC Thunder, and Sooners. I think that's because I value accountability and at least with those teams I know if the GMs/coaches are performing poorly at their jobs then changes will be made accordingly. Whereas with Dallas, we all know that the ultimate decision makers in the Cowboys' front office will never be held accountable for their missteps.
