It may be hubris on my part but the Patriots playing in Pittsburgh is not the very concerning possibility that, for example, it is in past Denver playoff matchups. I feel like playing in KC would be more concerning too. For Pitt my sense is BB has a decent handle on how to beat them anywhere.
#1 seed is the best possible outcome but getting the Bye is the more important step, IMHO. Hypothetically speaking, if we get the Bye but it's the #2 seed, and it means we have to play the AFCCG in Pitt, I can live with that...
