Ever since Jerry signed that Nike deal and decided to take on Pepsi and not Coke in the mid 90s is what started all of this. Then Jerry not approving Goodell (along with the Raiders and Saints), made things worse. Jerry's TV negotiations, bringing in billions for the NFL, just doesn't seem to matter. Fact of the matter is - people who have absolute power in the NFL do not like the Cowboys. They will see to it that they don't sniff the Super Bowl ever again. If 2017 and the Ezekiel Elliott saga wasn't enough evidence of that, then nothing will be. The people on the panel that decided to suspend Zeke were two Giants fans, an Eagle fan, and a former Commander. That's like having a Jewish man be tried by a jury full of *****. Not fair at all - but appointed by Goodell never-the-less. Yet Tyreek Hill is regarded a hero after belting his kid around (helping give Dallas a loss on Christmas Eve), when he should be put in prison. Zeke was totally cleared on all charges - yet still had a 6-game suspension.
So, yes, there is a conspiracy against the Cowboys.
If you want to go back even further, you can thank Mr. Ryan of NFL Films for labeling the Cowboys team as "America's Team" in 1978. Dallas was the glamorous franchise everybody loved until then. Dallas and their fans has had a bullseye on their backs ever since. Don't tell me that's not true - I lived it.
