You're right - no one cares about stuff like this, but Jerry thinks he needs to make a show out of everything he does. He gets far more satisfaction out of the franchise simply being in the news than he does about the on field performances.
For Jerry it's all about promoting the circus and maintaining the 'relevance' and 'interesting' part of the day to day operations. He fails to see (or is just totally ignorant) of the fact that building a dominant winner on the field will get him all the media attention he could ever want, but that isn't high enough on the list of priorities because win or lose, he is still getting what he craves most.
There is only one thing that will get Jerry to change and we all know what that is, but because the Dallas / Fort Worth are is such a melting pot it will never happen. There are far to many fans of other teams moving to this area that even if all Cowboys fans boycotted the games the stadium would still be filled on game days. Jerry wouldn't care if the stadium was 99% filled with cheese heads, Iggles turds, or Stealer fans, it will always be butts in seats.
