What happened: Las Vegas opened 3-0 under Klint Kubiak and now turns to its first division matchup of the season. The fast start has moved the Raiders from offseason reset talk into an early AFC West measuring stick.
Why it matters: The next result will do more than preserve an unbeaten record; it will show whether Las Vegas belongs in the division race right now. It also puts a brighter spotlight on Kubiak's early imprint on the Raiders after an offseason built around his system.
By the numbers: Las Vegas is 3-0 entering Week 4. Kansas City is also 3-0 after a 24-10 win over Miami last week.
What to watch: Sunday's matchup should give the clearest read yet on how sturdy the Raiders' unbeaten start is. A win would leave Las Vegas with an early edge in the AFC West race.
