Philly line would depend a great deal on how they look. All things being equal it could be 7. Assuming from your post that NE beats Indy, that game will be a PK. But IMHO wont be all home teams holding serve.
Haven't thought this far in advance, but if these do happen to be the teams that match up next week, I would once again be all over the pats to make another SB appearance.
