The Jets can also still get in by winning out (they play @Seahawks and @Dolphins, both free-falling) and getting one loss from the Patriots (@Dolphins and vs. Bills).
Otherwise there are very low-probability scenarios for the Raiders and Steelers. Essentially, the 7-seed is going to be a bad playoff team in almost every iteration, so the 2-seed is very attractive if the 1-seed doesn't work out. Hosting whatever 7-seed and then the Bills would be pretty decent all things considered.
I also think the 5-seed Chargers at the 1-seed Chiefs in the divisional round would be dangerous for the Chiefs.
