The only thing you need to be concerned about is this: we need to win out.
If we win out, we are 10-6.
If Baltimore, Denver, and/or Jacksonville loses one more game, the best they can finish is 9-7. So, if we assume that we win out (and why not? if we don't, who cares about the playoffs), then a single loss by any of these teams effectively eliminates them from the post-season.
It doesn't officially eliminate them, but if you take the assumption that we win out to finish 10-6, it essentially does.
Which is why, by the start of our game on Sunday, we may actually be in the driver's seat, so to speak. If Denver loses on Saturday, and Baltimore and Jacksonville lose their early games on Sunday, we would already know the path that lies before us....
