KANSAS CITY, Mo. (AP) — The Kansas City Chiefs defense was once again abysmal in a 38-20 loss to the Buffalo Bills on Sunday night in a rematch of the AFC title game. The defense watched the Kansas City offense turn the ball over four times without forcing one of their own. They gave up 315 yards through the air, 121 on the ground and 8.1 yards per play. And the Kansas City defense could not make a stop when the offense scored in the fourth quarter to make it a two-possession game.
