The Bills have the Chiefs' number in regular-season play. They are 5-1 against Kansas City in regular-season meetings since 2017 and won each of the last four matchups. It is when the stakes are at their highest that the Chiefs take control. They won each of the four playoff showdowns since Mahomes and Allen joined their respective teams.

The Bills' usage of James Cook, Patrick Mahomes' quick passing game and the familiarity between Buffalo and Kansas City will all play a significant role on Sunday.

The Bills have actually won four out of the five regular-season meetings over that span, but Mahomes, Reid and the Chiefs have dominated when it matters most, winning all four playoff matchups, the last three of which have been decided by a single posession.

It's that time of year, Bills vs. Chiefs for their annual AFC heavyweight showdown. Here's the broadcast and betting information.
