After loosing at home against the Jets, Ravens and again to the Ravens over the last 6-7 years, never dismiss any team in the playoffs. They all want to prove that they are the best by beating the best and will play 100+% against us (except maybe not the Dolts as that is not in their nature).
I like our chances at home, obviously, but if lesser teams have gone on the road and won the superbowl (like the 2007 Giants, and 2012 Ravens) I think every team thinks they can win once they make the playoffs.
The Patriots need to be consistently good in all 3 phases of the game, and they can beat anyone, anywhere anyday.
