Sunday in the NFL was all about the races at the top of the respective conferences. In the AFC, the Bills finally became the first team to vanquish the previously undefeated Chiefs, with a Josh Allen touchdown run sealing Kansas City's fate. The Steelers dispatched the Ravens with a quintessential Pittsburgh performance, down to a perfectly timed Mike Tomlin timeout swinging the game in their favor. Over in the NFC, the Vikings (mostly) cleaned up their offensive operations in a win over the Titans, while the Lions delivered one of the most impressive offensive performances of the season in a blowout win over the Jaguars.
