I mentioned this in the Week 5 NFL Games thread, but since you brought it up I'll re-post it here.
It seems strange that after next week the only games where the opposing crowd/venue might play a factor are the two division games at Miami and New Jersey. The game at Jacksonville will probably be 50-50 Pats/Jags fans, and the "away" game against the Rams in London should be pro-Pats.
All NFL teams, including the Pats, do better at home than on the road. I think that the Pats playing three road games in four weeks was overlooked by many with the team's 2-2 start. Seattle is an extremely difficult place to go play and come away with a win - but regardless of the outcome next week the Pats are set up well after that for a long stretch of games.
