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

Earlier in the fourth quarter, Nick Bolton stopped Allen on fourth-and-1 for no gain at the Kansas City 41. The Bills led 22-21 at that ... a third-and-4 on the play before the touchdown, and Kaiir Elam was penalized 11 yards — half the distance ...

Kansas City has been coached by Andy Reid for 12 seasons. The Chiefs have made the playoffs 11 times. They have now won nine consecutive AFC West titles, reached seven consecutive conference title games, gone to five Super Bowls over the past six campaigns and won three with a chance to make it four in New Orleans.

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?

The Chiefs have, of course. 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.

On the other, it left the Bills stuck in their own Groundhog Day prison, beating Kansas City to seemingly prove their legitimacy in the fall only to have their season ended by that same foe in the winter.

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.

The Kansas City Chiefs's 32-29 victory over the Buffalo Bills has been called into question following a number of controversial referee decisions.
