If you had asked me this during the middle of the season, I would have said no, but once you reach the divisional playoffs, any loss from that point on is a wasted opportunity.
Yes, we have young players like Dak, Elliott, etc. with a bright future ahead of them, but there's a lot more that goes into a season than just one or two players. Two years ago, we thought we were back. Then we lost Romo and Murray in 2015 and we went 4-12. Just because the future appears to be really good for the Cowboys does not guarantee we will be back in this position next year or in the next few years. You have to take advantage of your opportunities right now and let the future play out when it happens.
While I won't call this year a failure if we lose, given we ended up better than we hoped after losing Romo, I will say that losing any of the next three games will be wasting one of the best opportunities we have had in the last 10 years.
