‘“When you go on the road in the NFL, you’ve got to get used to [playing in hostile environments] because that’s a lot of what that’s about,’’ Brady said. “You go in there with however many guys — 46 active, five or six other guys, your coaches, a few fans in the crowd — but I think it’s always gratifying when you go in there and then by the end of the game you look up and there’s only Patriots fans left. I always think that’s pretty cool.’’’
