Ryan Tannehill is the X-Factor in Titans' Upset Bid Against Chiefs

The Tennessee Titans are on a miracle playoff run the likes of which hasn't been seen in the NFL in quite some time. The next stop on their wild journey is Kansas City, where they'll have their work cut out for them taking on the Chiefs.

There's a lot to like about the Titans as they head into Arrowhead Stadium, but quarterback Ryan Tannehill will be the big key for them as they try to topple the Chiefs on Sunday.

At this point, it's obvious that Mike Vrabel's offense is centered around bruising running back Derrick Henry, and through the first two rounds of the playoffs, it has worked out. The offense has controlled time of possession, and they've been able to play from ahead.

But they've also managed to sneak by with Tannehill throwing just 29 total passes. He has yet to be tested in earnest this postseason, and he hasn't quite shown the remarkable offensive prowess that had him sneaking into MVP discussions at the end of the regular season.

If the Titans are to pull off their upset bid against the Chiefs, he needs to be as sharp as a razor. Tannehill absolutely must find a way to keep up with Patrick Mahomes and Kansas City's high-octane offense if the Titans' defense isn't its usual self in shutting down the opposition.

It's important to remember that prior to this year, Tannehill had never really shown elite talent, never mind the ability to flash it under the spotlight. The Chiefs will be his biggest test yet.

He's the X-factor for the Titans. If he can show up in the AFC Championship Game, then Tennessee will likely be on their way to the Super Bowl.
