The Raiders don't have much to play for, but of course they don't want to be humiliated at home and it's not like a game on Sunday where it can get lost in the shuffle. The Broncos have clinched the division so they are playing for the highest possible playoff seed.
The last line I saw is 10 points. Could be a blow out, but I think it will be closer than that. I'll guess Broncos 23 Raiders 17.
