I remember when the Cowboys used to struggle sometimes late in the regular season because they were so focused on the playoffs. That's when Aikman, Smith, Irvin, etc. were all at their best.
Now we have the opposite. A team that looks unstoppable in the regular season and then looks like the worst team in the NFL in the playoffs.
It's the culture around this team now. "Good" is good enough. Being relevant is enough. Being a champion is not necessary.
