A funny thing is confidence. A team that rolls feels they can roll - and even when they hit harder opposition, they can play to their level and still win. So it really doesn't matter who we play I think. If the team thinks they can beat anyone, they can. Just look at SF. They felt they could beat NE in NE, and they did. But the Seahawks felt they were on fire the last few weeks, and they obliterated poor SF. Is Seattle that much better than NE? No. They would probably lose in NE.
As long as the Broncos really feel they can't lose.. they probably won't.
