That's how the West was won.
The Kansas City Chiefs clinched the AFC West title with their 23-16 win over the New England Patriots and the Oakland Raiders' 42-21 loss to the Tennessee Titans.
This is K.C.'s fourth consecutive division title and marks the Chiefs' sixth playoff appearance in seven seasons under coach Andy Reid.
At 9-4, the Chiefs are currently slotted into the No. 3 seed in the AFC, one game behind the Patriots (10-3) and one game ahead of the Houston Texans (8-5).
While Oakland cannot win the division, the Raiders (6-7) are still alive for a postseason berth. Oakland is two games behind Pittsburgh (8-5) and Tennessee (8-5) for the final playoff spot.
