Well lets see. They've got the best offense in football. The best kicker. The best QB. The best TE. The best coach. A very good defense that can cause turnovers and get pressure on the QB. They're also playing in a league where most of the other teams are either bad or mediocre. Who is possibly going to beat them? GB is the only team I give a chance if they are healthy.
Fact: the team with the best kicker never loses.
Not really sure what point you're trying to make here. My post mentioned a lot more than just a kicker.
I think you're crazy if you think GB is the only team that you even give a chance to. Your points are valid but there are plenty of games on their regular season schedule that they could lose. They were losing to the Jets at home in the 4th quarter, what makes you think that's a sure win in week 16 when the Jets are the home team?
Bills usually play them tough, the Giants, while not as talented have found ways to win against them before in similar circumstances, the Broncos are still undefeated and while they don't seem to be as good a team as their record indicates, it's in Denver and should be a tough game.
All in all, it's certainly possible they go undefeated but right now I think it's unlikely. Don't get me wrong, they look amazing but a lot can happen in any given football game.
