1) Kansas City’s hopes for earning the top seed in the AFC playoffs taking a hit. News flash: The Chiefs weren’t going to go undefeated this season. They were playing too many one-score games, and it was only a matter of time before that caught up with them, as it did in Sunday’s 30-21 loss at Buffalo. The Chiefs, now 9-1, still have a one-game lead in the race for that AFC first-round bye, but the 9-2 Bills own the crucial tiebreaker in the event both teams end up with the same record. The 8-2 Steelers are a player in this conversation, as well. But here’s the hard reality: The Chiefs don’t need the top seed to return to the Super Bowl and chase a three-peat. They had to play two road games in the playoffs last season, and they found ways to win those contests in Buffalo and in Baltimore. The takeaway from that accomplishment is that it doesn’t matter where the Chiefs play or how they’re seeded when the playoffs begin. What is crucial is that opponents bring the same mindset that the Bills brought to their win on Sunday. Buffalo wasn’t content to create an opportunity where they could have a supposedly safe lead late in the fourth quarter with Patrick Mahomes having one more shot at winning the game. Instead, it gave the ball to Josh Allen on fourth-and-2 and told him to win the dang thing. That’s how you beat the Chiefs — not by hoping for the best-case scenarios when the playoffs begin. They’re going to be a house favorite once again. The only question is whether another AFC team has the nerve and the talent to do what Buffalo just did come tourney time.
