The Cowboys and Falcons have faced each other quite often, which may seem surprising. If you take out the Cowboys’ three divisional teams, whom they play twice a year, then only four other NFC teams have played Dallas more times. One of those teams, the Cardinals, used to be in the same division while the other two teams - the Packers and 49ers - were frequent playoff enemies back in the day.
There’s quite a bit of history here, but you could easily argue that the last three games between these three teams have been extremely memorable games, and all for very different reasons.
