I'm not a happy fan by any stretch but I totally disagree, here. Once you get into the dance, anyone has a chance. This defense is plating at a high level. If the offense starts playing like 2016 and the first half of 2017 they can compete with anyone (including the Rams and Saints). If they don't then it will be one and done. No one though Prescott could go toe to toe with Rodgers ins 2016, either. And, stats-wise, he actually out played him. The defense let us down that week, not the offense.
For the record, I have my doubts that that type of recovery is on the horizon but no one gave the Giants a chance to win it all in 2007, either. The defense caught fire at the right time and the offense played complimentary football to beat the (then) unbeaten Patriots. It's a strange league and the ball bounces strange ways. Again, I'm not saying the Cowboys will replicate that type of run but I'm sure as hell not going to sit here on my couch and act like it doesn't happen, either. Get in the dance. That's goal #1. From there it's some intense football and, face it, a bit of luck.
