If the Steelers win, the Chiefs will be going to New England to play the No. 2 seed Patriots.
If the Bengals win, the Chiefs will be going to Denver to play the No. 1 seed Broncos.
The Steelers are the lowest seed (No. 6) so they would play the highest seed (No. 1) no matter what. The Bengals are the No. 3 seed so if they won the Chiefs would be the lowest seed and then play the highest seeded Broncos.
Which one should they want?
I'd pick the Broncos. The Chiefs have proven they can win there after their 29-13 win in Denver earlier this season. They'll be starting Peyton Manning who has not been very good all season. The Broncos won 12 games but Manning was not the reason for that. The Chiefs have the best shot here because Manning is an unknown.
I wouldn't pick the Patriots mostly because ... well, it's the Patriots. They're very experienced, they have the AFC's best quarterback and the NFL's best coach.
