I had hoped that the fact that New Orleans Saints had failed to come with their A game in five straight games (before their three losses they had two near-losses to non-playoff teams, one of whom was the Washington Redskins), that the Cardinals would be able to knock them off. I wonder if once New Orleans was assured of home field advantage throughout the playoffs, they put a lot of their playbook under lock and key for the playoffs. In any event, the Cardinals' A-game was MIA in the Superdome.
However, history does not side with teams who win close, high-scoring playoff games in the previous round. I am old enough to have been a San Diego Chargers fan in the late 70s and early 80s, (the Cardinals had yet to come to Arizona) and witnessed the nerve-wracking Charger victory over the Miami Dolphins. However, the Chargers' season came to a screeching halt in the Freezer Bowl in Cincinnati the following week, losing 27-7 to the Bengals. I link to an account of that game on the title.
Congratulations to the Who Dat Nation. At this time the Vikings lead the Cowboys, which suggests to me that Brett Favre and company are going to have to rehearse the silent count for the NFC championship game, because they are going into the loudest stadium in the NFL.
