As least, I hope we all do. If you're just learning this now, wake up for cryin' out loud. It's the playoffs.
Seeing as how the Chiefs play in the AFC West and the Ravens haven't faced them since Week 1 of last year, there's a lot about head coach Todd Haley's ballclub that you might not know.
With that said, here's a quick rundown on the team from the BBQ capital of the world:
The Chiefs won the AFC West with a 10-6 record despite going only 2-4 in division play. This season marks a huge turnaround for the boys from Kansas City, who finished 4-12 last season in Haley's first year as coach.
Kansas City finished the regular season with the league's 12th-ranked offense, and it leans heavily on a physical, downhill rushing attack. Pro Bowl running back Jamaal Charles teams up with veteran Thomas Jones to give the Chiefs a dynamic one-two punch out of the backfield, but Charles is the main guy to watch.
The Texas product came up a painfully short of setting the NFL record for yards per carry in a single season, and his ability to break a big play at any time was the key component in the Chiefs putting up 164 yards on the ground per game, best in the league.
The Chiefs also have a physical force out wide in receiver Dwayne Bowe, who was another Kansas City selection to the Pro Bowl this season. Bowe led the NFL with 15 receiving touchdowns, and at 6-2, 221 pounds, he provides a presence both deep down the field and over the middle, where he's tough to bring down in space.
Matt Cassel is the guy who runs the show for KC and keeps all the pieces in place. The former Patriots quarterback posted a very Joe Flacco-like season in that he was statistically solid (he threw for 3,116 yards, 27 TDs and 7 interceptions) and got the job done, but didn't really light the world on fire.
Defensively, the Chiefs allow 330 yards per game (14th in the league) and a little over 20 points per contest.
They play a 3-4 up front under defensive coordinator Romeo Crennel, and have an athletic front-seven led by linebackers Derrick Johnson and Tamba Hali. Johnson is the run-stopper in the middle, while Hali, the former Penn State star, brings serious pressure off the edge. He recorded a career-high 14.5 sacks this season, second-best in the NFL. Overall, the Chiefs posted 38 sacks on the year
On the back end, the Chiefs are pretty young, as they start two third-year corners and a rookie free safety. That safety - Eric Berry - proved to be a ballhawk in just his first pro season, leading Kansas City with four interceptions, one of which he returned for a touchdown.
Kansas City's defensive weakness is inside the red zone; they've allowed touchdowns on over 70 percent of opponents' trips inside the 20, the second-worst average in the league.
Placekicker Ryan Succop went 20-for-26 on the season with a long of 53.
The Chiefs will be aided by the fact that they're playing at Arrowhead Stadium, a place where they went 7-1 this season. Their recent playoff history doesn't bode well for them, however.
Kansas City has lost its last six playoff games, and hasn't earned a postseason victory since January 1994.
That victory came over the Houston Oilers. Yeah, that was a long time ago, all right.
