Consistency has pretty much been the death knell of this team. The best teams in the league play consistent football. They don't play down to their opponent, they just go out there and play their game. The SB winning cowboys teams all had it and it seems to be something that is very difficult to replicate. I suspect a large part of this is finding that fine amalgamation of talent and coaching.
I wouldn't expect this team to go anywhere until they fix this problem, and for those of you screaming for the firing of the coaching staff etc - this isn't something that started today, it's been this way for all of the 10 years that Garrett was coach, it was this way when Wade was HC and prior to him when Parcells was coach. This team is notorious for playing down to opponent and that is the identity of this team. It does not impose it's will on their opponents and that is the problem. The injuries didn't help yesterday but this issue was there last year and it was here this year when Dak was playing. Why do you think we see performances like the ones against the Jets last year, or for a team this loaded with playmakers is eeking out wins against the Giants?
