Although the Giants were a 5th seed, I believe, they did have 3 road games en route to their SB. I think Pitt and maybe the Raiders??? did the same this decade. Furthermore, what team really worries you about going on the road for? The Packers played the top AFC team and damn near beat them on the road, and either did, or damn near beat the top 3 NFC teams on the road (Atl, Phi, Chi).
