It would be great to do that but didn't the Steelers do it just a couple of years ago? I think they won three on the road and then beat Arizona in the SB.
They did it and they didn't even get the benefit of a gimme in round 1.
The guys on Sirius were just talking about the very real possibility of the Packers getting the 6 seed, winning their first two and the Saints hosting the NFC Championship.
