Sports fans always enjoy themselves an in-division rivalry.
But football fans in Kansas City also get excited when the Chiefs take on a couple of teams outside of the division.
Let's take a look at five of Kansas City's non-divisional rivals.
In Week 14 of the 2006 season, the Baltimore Ravens came to Arrowhead Stadium in hopes of leaving Kansas City with a rare December road win.
The Chiefs were looking to extend their December home game winning streak to 19. But it turned out the complete opposite.
The Ravens took a 13-0 lead in the third quarter as Arrowhead Stadium turned silent and fans left early. The Chiefs eventually fell, 20-10, losing at home in December for the first time in over a decade.
In more recent memory, the Ravens picked up another win at Arrowhead Stadium, but this time it came in January 2011 in an AFC Wild-Card matchup. The Chiefs at led at one point, 7-3, which was their first postseason lead in 13 years. But the Ravens quickly put that behind them and eliminated the Chiefs, 30-7.
This year, the Chiefs and Ravens will face off at Arrowhead Stadium on October 7 in Week 5.
The Chiefs have faced the Buffalo Bills in each the past four years.
They say familiarity breeds contempt.
All four of the aforementioned meetings also occurred at Arrowhead Stadium. The Bills won three of those contests by a combined score of 121-61.
In 2008, the Chiefs allowed a franchise-high 54 points against the Bills, losing 54-31 in the final year of Herman Edwards' tenure as Chiefs head coach.
In the 2009 matchup, Jamaal Charles—who took over for Larry Johnson at RB—was doing his best to keep the Chiefs in the game, as he broke off the longest-rushing touchdown of his career, burning Bills defenders for 76 yards.
However, it was not enough for the Chiefs as they lost again to the Bills, 16-10.
The Chiefs were becoming one of the league's most surprising teams in 2010 when they hosted Buffalo on Halloween. But for Chiefs fans, it was this game against the winless Bills that provided the scariest moments.
Tied at 10 late in the fourth quarter, Bills quarterback Ryan Fitzpatrick threw an interception to Eric Berry, as the Bills were trying to position themselves for a game-winning field goal.
In overtime, Bills kicker Rian Lindell made what appeared to be the game-winning field goal—but the kick came after then-Chief head coach Todd Haley tried icing Lindell with a timeout. His following kick hit the crossbar, giving the Chiefs new life.
After missing an earlier game-winning field goal attempt in overtime, Kansas City kicker Ryan Succop redeemed himself, making a 35-yard field goal with five seconds left in OT to give the Chiefs a nerve-wracking 13-10 win.
On top of that, who better than Gus Johnson to call a close game?
In last year's season opener, the Bills drew first blood and never looked back, destroying the Chiefs in one of the toughest home-opening losses in franchise history, 41-7.
The Chiefs and Bills will meet in Buffalo on September 16 in Week 2.
Despite the fact that the Green Bay Packers and the Chiefs are in opposite conferences and play once every four years, their games have always been big.
In 2003, both teams met in Week 5 at Lambeau Field with all eyes on both teams to see who would remain the NFL's only unbeaten team. The game took a lot of twists and turns for both sides. Tied at 34, the game was sent to overtime to decide who would remain undefeated.
Chiefs kicker Morten Anderson missd a 48-yard field goal, but Ahman Green fumbled the ball, giving Kansas City another chance.
Trent Green, who threw for exactly 400 yards that day, took advantage of this opportunity on the very next play, connecting with Eddie Kennison on a 51-yard touchdown pass.
The Chiefs won, 40-34, starting the season, 5-0.
In 2007, Brett Favre was on fire with the Packers, but wanted to do something he had never done in a Green Bay uniform.
Favre had defeated every NFL team in his Packer career—except for the Chiefs. Favre reached this mileston as the Packers defeated Kansas City, 33-22. Even more ominous for Chiefs fans, this game was the first of 12 straight losses—a streak that carried over into the 2008 season.
In 2011, Romeo Crennel was hired as the interim head coach to replaced the dismissed Haley. Given only six days to prepare for the 13-0 Packers, Crennel named Kyle Orton the new starting quarterback for the Chiefs. Despite the short turnaround time following the coaching change, the Chiefs still managed to upset Green Bay, 19-14, giving the Packers their first and only loss of the regular season.
The Packers and the Chiefs will meet in Week 4 of the preseason on August 30.
The Chiefs and the Indianapolis Colts have had an interesting non-divisional rivalry.
From 1995-2006, the Chiefs had played in only four postseason games, with three of them being against the Colts.
The Chiefs were in position to defeat the Colts in the 1995-96 AFC Divisional Playoff game, but lost 10-7 thanks in large part to kicker Lin Elliot missing field goals from 35, 39 and 42 yards.
Following the 2003 regular season, the Chiefs hoped the magic of their 13-3 campaign would continue during the playoffs, but Peyton Manning and the Colts won 38-31 in the only playoff in NFL history that did not feature a single punt.
After the 2006 season, the Chiefs and Colts met again in the playoffs. Even though Manning threw three interceptions and only one touchdown pass, the Colts managed to beat the Chiefs more easily than some thought, 23-8.
In a recent regular season matchup, Kansas City bested the Colts only when Manning is not behind center.
The Chiefs took advantage of Manning’s absence last year, picked up their first win ever in Indianapolis, 28-24, overcoming a 17-point deficit.
The Chiefs and Colts will meet on December 23 in Week 16 in Kansas City for the final home game of the season for the Chiefs.
There is not much to say about this rivalry, other than this:
Both teams want to be considered the best NFL team in the state of Missouri.
Almost annually, the two teams meet in the preseason for what is known as the Governor's Cup.
The Chiefs and Rams will square off in Week 2 of the preseason on August 18 in St. Louis.
