The Cowboys have been historically good yet they've been terrible for an entire decade.
They did that in the 80's also. Well making the NFC champs as many time as they did was something positive but many wanted more....but as for THIS ETIRE DECADE all I can say is shit happens ......the Colts and Saints are the best and teams like Dallas and the 49ers are now struggling. But Dallas will always be THE NFL POWERHOUSE!!!!
