You have the facts on your side, which is very annoying, but it's a Division rivalry. In other words, far, far stranger things have happened in the NFL.
Also, what I am about to say is completely unscientific and unsupported by the records of either KC or DEN and, indeed, betrays virtually everything factual that I've learned in 50 or so years of following the NFL since the days of Chuck Bednarik, BUT, I'll say it anyway: Denver has now won 10 in a row; my gut is that they are good, but not that good and I think they might be ready to lose a game.
