My opinion why DC.com was shut down. (This is my opinion and I'm going to believe my opinion no matter what anyone else says.)
When Jerry went after Goodell's contract for suspending Zeke, Goodell retaliated by going after DC.com.
Dallas is in control of their own merchandising. We all know that, but it isn't merchandising if your naming other teams player or giving descriptions of the game. In order to give descriptions of the or name other teams players, you need NFL permission. So Goodell retaliated against Jerry and went after DC.com. At the same time (since retaliation is Illegal) he had to make sure all of the other NFL teams were in compliance with regulations on their website. So Dallas had to change their website to an NFL approved platform.
1)So Zeke was suspended, erroneously by some.
2)Jerry went after Goodell's contract, in retaliation for Zeke's suspension.
3)Then Goodell went after Jerry for retaliation on his retaliation, about Zeke. And ended up taking down DC.com.
So we lost DC.com due to a pissing match between two egomaniacs. Does that make sense to anyone?
