It always feels like whenever the Dallas Cowboys face the Seattle Seahawks, it becomes a defining moment in the season. In 2014, the Cowboys showed the world that the were for real after coming away with a big road win. It was their fifth straight win and let fans know this team was playoff bound. In 2015, they showed they were anything but real as a fifth straight loss flushed away any hopes of a playoff run. And then last season, the Cowboys needed to run the table and win their last five games, but the Seahawks came into AT&T and ruined that, eliminating the Cowboys from playoff contention.
