KEY MATCHUP Chiefs QB Patrick Mahomes vs. Bills pass defense:

The superstar will face the league’s No. 1 pass defense and overall defense, one week after he was 30 of 39 for 404 yards and five TDs against the Steelers. He became the first player in NFL history with at least 400 yards passing, five TDs and fewer than 10 incompletions in a postseason game. Mahomes was 33 of 54 for 272 yards with two touchdowns and two interceptions in a loss to Buffalo in October.

Sam Farmer’s pick: Allen and Mahomes trade punches — both will throw for a ton and run for at least a couple first downs — but it’s the better defense that decides this one. Bills 31, Chiefs 28
