Roseman has what the Cowboys do not have, an owner pushing the envelope continuously. He won't fire Roseman for failing but he would for not going far enough.
It was Lurie behind that whole Dream Team and handing the reins over to Chip Kelly and demoting Roseman.
And it was Lurie behind the whole t shirt thing and having Buddy Ryan take on Johnson and Dallas. Lurie hates Booger and the Cowboys, he is ecstatic to be in the SB, the only thing that would have made him happier was to beat DAL on their way to the SB.
