Dallas are 1-5 is their season and superbowl hope in their own building and playoff over?

what one reason why Dallas having a bad season now it goning to be even worse that Tony Romo going to miss 4-8 week sad day to be a cowboy fan. Could it be of the persure with the new stadium and superbowl explanations or the coaches stuff not getting players focus and ready to play football or not making smart play calling.All that talent they got on that team they are falling apart just like the vikings are.
