That's because with the amount of talent they have they SHOULD be winning. The cowboys are like the yankees of football, spend an insane amount of money and if they don't win its expected that something has to change!
I agree with the packer fans here, there is no reason why you should be "ok" with things how they are now...you just lost to the worst team in football. After the cowboys come into town you might not be in second place anymore, either.
