The Denver Broncos (7-8) are technically still alive in the AFC playoff hunt, but not by much. The New York Times estimates that Denver has a 6% chance of reaching the postseason.
There are two ways the Broncos could still make the playoffs. The first way would be to win the AFC West. For that to happen, Denver would have to win out and the Kansas City Chiefs (9-6) would have to lose out.
Kansas City losing both of its remaining games seems extremely unlikely, so the second option might be more realistic (albeit still unlikely) for the Broncos. The second option would be to make the playoffs as a Wild Card team. The best-case scenario would be getting in as the sixth seed.
In order to make the playoffs as in a Wild Card spot, Denver would need a lot of help from other teams. With that in mind, here is a handy Week 17 rooting guide for what results would put the Broncos in the best position to earn a Wild Card playoff berth.
