Bengals are a tough matchup for both KC and Buffalo for whatever reason, and prove the old saying that the NFL is all about matchups.
Burrow is 1-5 against the Browns in his career, yet people were calling KC's stadium Burrowhead because of how the Bengals always seemed to win against KC.
This is why playoff seedings and matchups matter. Think of NE's Super Bowl runs where all they had to do was win 2 homes games vs the Titans and Jaguars and they're back in the SB.
If the Bills secure the #1 seed and things fall a certain way it could be wins at home against the Jets and Texans (or something similar).
Or it could be Wildcard Week vs Cin, then the Ravens, then KC.
