Pittsburgh or Tennessee aren't exactly pushovers, at least in the case of Titans, they have a great defense and perhaps the closest thing to a new Marshawn Lynch 2.0.---Derrick Henry. Their QB is a bit past his prime and who's role is more as a good game-manager than being expected or predicted to pass for 4,000 yards and 30 TDs. Still, of these two other AFC contenders to Chiefs crown, Pittsburgh presents the best, most potent and all-around threat to defeat them in a potential AFCCG scenario.
