Question

What are the only two teams that have never played Pittsburgh, Green Bay or Dallas in a playoff game?

Answer

The Saints and Texans. Both Green Bay and Dallas have played postseason games against all of the other teams in the NFC. The Steelers have played all of the AFC teams except Houston. While the Packers, Cowboys and Steelers have never played the Saints in the postseason, oddly, all have won Super Bowls played in the city of New Orleans.
