IF the Bills are the 1 seed, it's almost certain KC and CIN are #2 and #3.
Assuming both of those teams win their wildcard games, the Bills would play the winner of the AFC South or the Ravens/Chargers/Dolphins/Patriots
CIN and KC playing each other in the Divisional round is ideal.
If the Bills are not the 1 seed, we will have to beat the Ravens/Chargers/Dolphins/Patriots and then play KC or CIN in the Divisional Round.
