Their secondary gets torched year after year after year after year.
Nobody fears their defense.
The offense was good enough to win the whole thing, but with both starting tackles and Dak out for the year well.....yeah. Also I think it's time for Tyron Smith to hang em up. Dude is a likely hall of famer, but injuries have caught up to him. He's been great for a decade, but Dallas needs to re-build that offensive line.
