Patrick Mahomes and Josh Allen will face off for the ninth time in their careers, with a lot riding on the outcome. While Allen holds a 4-1 regular-season re

Allen and Mahomes get a lot of the shine in this rivalry, but Chiefs head coach Andy Reid and Bills head coach Sean McDermott have a history, too. McDermott was an assistant under Reid with the Philadelphia Eagles for ten years before Reid fired him in 2010 as the team’s defensive coordinator.

Josh Allen and the Bills played another playoff classic against Patrick Mahomes and the Chiefs. Once again, it was Kansas City coming out on top. The Bills fell to the Chiefs 32-29 in the AFC Championship Game as Kansas City continued their quest for an unprecedented third-straight Super Bowl.

Despite the loss in the AFC championship game, the Bills enjoyed a lot of success this year. Buffalo won the AFC East for the fifth season in a row. Allen is an MVP candidate. James Cook rushed for over 1,000 yards for the second straight year and the team had the best turnover differential in the NFL.

The Kansas City Chiefs won another postseason matchup against the Bills by a final score of 32-29 to stay undefeated in their postseason matchups with Buffalo in the postseason during the Patrick Mahomes and Josh Allen era.

Worthy led the Chiefs with the most impressive performance of his rookie season, gaining 101 all-purpose yards and a touchdown.

The Bills have gotten increasingly used to taking the field without some of their most impactful defenders. That trend continued on Sunday when Christian Benford was felled by injury.

In the passing game, there may also be some advantages to press. Khalil Shakir working against Chamarri Conner in the slot is one of them. Shakir is Buffalo's most reliable pass-catcher, while Conner is the least reliable of Kansas City's defensive backs in coverage.
