“It’s one of those environments that is electric,” Giants linebacker Mathias Kiwanuka said. “You have two teams that share a building, we hang out, we live and everything within close quarters. We share some fans. We just understand that it’s a big game regardless of how often we’re going to see them just because of how passionate the fans are on both sides.”

There will be plenty of passion, for sure. And probably not much defense, because neither team has shown an ability to cover receivers. That bodes far better for Eli Manning, who’s having an excellent year despite the Giants’ 7-7 record, than it does for Mark Sanchez and the Jets (8-6).

Jets fans will be Big Blue afterward.
