It was yet another season-ending underperformance by the Buffalo Bills’ defense in Sunday’s loss to the Kansas City Chiefs.

Kansas City has been coached by Andy Reid for 12 seasons. The Chiefs have made the playoffs 11 times.

It's Buffalo Bills vs Kansas City Chiefs for the AFC championship. Can Josh Allen and James Cook lead the Bills to win vs Patrick Mahomes and company?

They are making their third straight trip to the big game, and fifth in six years, as they try to become the first franchise in NFL history to raise three consecutive Lombardi Trophies come Super Bowl Sunday. They might as well start scheduling these February business trips.

The Bills cannot get by the Chiefs in the playoffs. It happened again Sunday in a 32-29 loss to Kansas City in the AFC Championship game. The last three defeats have been by a grand total of nine points -- all separate three-point losses.
