From the franchise's 1960 inaugural season until 2005, the Cowboys lost 9 games when scoring at least 30 points at home. That's 46 seasons.
In the last nine seasons, the Cowboys have already equaled that, losing 9 games when scoring at least 30 points at home. On average, since 2006, we've lost one such home game every year. It happens to the average team about once every six years. We lost six such games in three seasons from 2011-13, when no other team lost more than two.
Now some good news. 2014.
