Buffalo Bills linebacker Von Miller paid Kansas City Chiefs quarterback Patrick Mahomes the ultimate compliment. He not only compared him to the late NBA superstar Kobe Bryant, but Miller also said he wished he had a magic play that would stop Mahomes in his tracks.

The Bills led in the fourth quarter, 22-21, and even had the ball at midfield before getting thwarted on 4th & 1 and turning the ball over on downs. The Chiefs took the ball and scored, taking a 29-22 lead.

The Kansas City Chiefs took that assertion to the brink once again Sunday night in the AFC Championship.  But what else would you expect? In beating Buffalo 32-29, the Chiefs won for the 12th time this season in a one-possession game without losing.

Obviously, the usual suspects -- quarterbacks Josh Allen and Patrick Mahomes, among others -- will have a big say in which will go on to represent the AFC in the Super Bowl.

Here are three keys to a Bills win vs. the Chiefs: Mahomes is good enough in the pocket that he can beat you even when everyone is covered. He’s great at buying an extra second or two and finding someone uncovered down the field, and in the playoffs, tight end Travis Kelce has often been that person.

Unlike last year's playoff loss to the Kansas City Chiefs, the Buffalo Bills have their defensive leader available for the AFC Championship Game.
