The Broncos are a top tier team. They may not be playing their best right now but if they get it together in time for the playoff games I see no reason why they couldn't beat any AFC team to get to the superbowl.
Also I don't think the Patriots are as unbeatable as most people think. Yes, they are going to be tough as hell to beat at home, but I can see a few teams upsetting them in the playoffs (Colts, Broncos, and maybe even the Steelers if they get their shit together). I mean just look at Green Bay they weren't at home last week, but everyone thought they were unbeatable and they got beat by the Bills.
