The 2019 Cowboys remind me a bit of the 2008 Cardinals. Their offense was built around Kurt Warner and his top three receivers. They were explosive. The defense was sketchy but it came on in the playoffs.
They could win and lose all of those. Right now the NFC is
Green Bay
New Orleans
Seattle
Dallas or Philadelphia
San Francisco
Minnesota
Nobody's taking the wild card from the teams that don't win the NFC North or the NFC West, so St. Louis is probably out.
