They just have gotten so arrogant. They're good but I don't they're that good. They did beat some good teams but usually when those teams were struggling (SD in particular). I might feel differently if they were a little humble about it.
On the other hand, I'd love to Favre get another ring. He's been a great player and stayed with the team/town that made him. Can he beat NE? If they played in the frozen tundra, definitely yes. Neutral field, maybe.
