Assuming we're out of the wild card running (since it would take a miracle for us to lose the division and make the playoffs), the playoff picture has become very simple. With the Broncos eliminated, only the Chargers and Raiders can knock us out of the top spot in the division. To hold them off, the magic number is 3 for the Chargers and 2 for the Raiders. That is, any combination of 3 Chiefs wins and Chargers losses (say, 2 KC wins and 1 SD loss) eliminates the Chargers, while any combination of 2 for the Raiders OR a victory over them in week 17 knocks them out. So, if we win our next two, and SD losses one of the next two, we will clinch the division before the Raiders game.
