Wrap-up: Broncos 38, Raiders 24

What it means: The Raiders, San Diego Chargers and Kansas City Chiefs are 4-4 and tied for first place in the AFC West after all three teams lost at home Sunday.

The Denver Broncos are 3-5 and one game off the pace in this hot mess of a division. The Raiders -- who went 6-0 in the AFC West last year -- were primed to be 6-2, but they have lost back-to-back home games to Kansas City and Denver.

What’s next: The Raiders have a quick turnaround. They will play a crucial AFC West game at San Diego on Thursday night. Denver plays at Kansas City,
