The Kansas City Chiefs are undefeated no more. The Buffalo Bills handed them their first loss of the season on Sunday, 30-21, snapping a 15-game win

After Mahomes threw another pick to seal the Chiefs' fate, the two superstar quarterbacks met at midfield for a postgame exchange . Mahomes had a five-word message to Allen that seemed to promise the two will see each other in the playoffs: "We'll do it again, baby."

And leave it to the Buffalo Bills, of all teams, to settle the issue behind their remarkable quarterback.  Allen bolted from the pocket on a fourth-down play with just over two minutes on the clock and didn’t stop until he delivered a finishing blow with a 26-yard touchdown run that essentially sealed the 30-31 verdict in a thriller at Highmark Stadium.
