You're free to disagree with facts, but Big Ben has performed atrociously on the road in recent seasons.
I don't see anything to indicate that their defense matches up better this year than in any other year. They played more man a couple of weeks ago, but Brady still had 300 yards and the Pats put up 27 points, which is one of their best offensive outputs at Heinz, and it's also identical to what they put up in last year's regular season meeting.
If you don't think the Pats' offense will perform considerably better with home field and with Hogan back, you're a clown.
Similarly, the defense should perform better with KVN and Harrison, and possibly Alan Branch returning.
