Looking back at the Kansas City Chiefs' 2014 season is like riding a rollercoaster—plenty of ups and downs.

Not only did they beat the two No. 1 seeds in this season's playoffs, the AFC's New England Patriots and the NFC's Seattle Seahawks, but they also fell to two of the teams picking at the top of the draft this April, the Tennessee Titans, who pick second, and the Oakland Raiders, who pick fourth.

With all of the swings in an emotional journey for Chiefs Kingdom over the past five months, let's take a look at some of the better times from this past season.

Here we'll count down the most memorable moments of the Chiefs 2014 season:

1. Cairo Santos' game-winning field goal in San Diego

While the win over the Seattle Seahawks in Week 11 capped-off a five-game winning streak for the Chiefs, the beginning of that streak came from the 23-20 win over the then 5-1 San Diego Chargers at Qualcomm Stadium in Week 7.

Early in the game, Jamaal Charles broke Priest Holmes' career rushing record on a spectacular 16-yard touchdown run (which we'll get to), and that would be the last touchdown for the Chiefs until the fourth quarter.

Anthony Sherman's 11-yard touchdown reception on the first play of the fourth quarter gave the Chiefs a 20-14 lead with 14:50 remaining in the game, but the Chargers would come back.

Nick Novak's 48-yard field goal tied it 20-20 with 2:04 left in the game, and the Chiefs were given the ball at the 8-yard line after the ensuing kickoff.

It was a two-minute opportunity for the Chiefs, who were 2-3 at the time in a key road divisional game, to drive down the field and win a crucial game.

That's exactly what they did.

The back-to-back passes from quarterback Alex Smith to Dwayne Bowe for 19 yards, then to Travis Kelce for 16 yards, set up Cairo Santos' game-winning 48-yard field goal.

On his sister's birthday, Santos, the Chiefs' rookie kicker, hit the biggest field goal of his career when his team needed him the most.

2. Beating the defending Super Bowl champion Seattle Seahawks 

Coming into that matchup against the Seahawks, the Chiefs had won four straight and were riding high after a tough road win over the Buffalo Bills the week before.

Jamaal Charles dominated this game with 20 carries for 159 yards and two touchdowns, but the resonating storyline after this game was that the Chiefs could win while not playing a perfect game.

It was something to notice as Seahawks running back Marshawn Lynch finished the game with 124 yards rushing and quarterback Russell Wilson completed over 60 percent of his passes and had two touchdowns as well.

Alex Smith threw for 108 yards and the Chiefs turned over the ball twice, but the defense stepped up in the fourth quarter by holding the Seahawks scoreless and stopping them on three fourth-down attempts late in the game.

The Chiefs walked away with a 24-20 win and moved to 7-3 on the season, the highest point of the 2014 campaign.

3. Jamaal Charles becoming the Chiefs' all-time leading rusher

Jamaal Charles became the Chiefs' all-time leading rusher in Week 7 on the road against the San Diego Chargers.

He passed Priest Holmes' record of 6,070 career yards rushing (2001-07) in that game, finishing with 22 carries for 95 yards and one spectacular touchdown run.

The record-breaking run came on the first play of the second quarter, a 16-yard touchdown run that culminated with Charles leaving his feet as he fought to get into the end zone.

He was hit by Chargers first-year cornerback Brandon Flowers, who had spent the first six years of his career with the Chiefs, and spun 360 degrees before landing in the end zone.

Coming into the season, Charles needed just 248 yards to break Holmes' record.

Over the past two seasons, Charles' 33 total touchdowns are the most by any player in the NFL.

4. Justin Houston breaking Derrick Thomas' sack record

The most revered record in Chiefs history was broken this season. 

Derrick Thomas, arguably the most storied player in Chiefs history, compiled 20 sacks during the 1990 season, a record that stood for more than 20 years.

Justin Houston finished the 2014 season with 22 sacks, breaking the revered record and finishing just one shy of the NFL all-time record (Michael Strahan – 22.5). Houston's 2014 season will be one that's talked about forever among Chiefs fans and football aficionados.

Heading into the last game of the season against the Chargers, there were two main storylines for the Chiefs.

They needed some outside help for a shot to get back into the playoffs for the second straight season under coach Andy Reid, and the second storyline was that Houston, who had 18 sacks coming into the game, needed two to tie and three to break Thomas' record.

In the most poetic way possible, Houston broke Thomas' record on a strip-sack of Chargers quarterback Philip Rivers in the second half of the game.

The strip-sack was a staple of Thomas' game throughout his 11-year NFL career, all of which came with the Chiefs. So it was a fitting way for the record to be broken while unintentionally paying homage to one of the best players to ever wear a Chiefs uniform.

Thomas still sits as the Chiefs' all-time leader with 45 forced fumbles.

5. The 41-14 win on Monday Night Football over the New England Patriots

If beating the Seahawks, the NFC's No. 1 seed and defending Super Bowl champions, was one of the top moments of the Chiefs 2014 season, then beating the Patriots 41-14 on Monday Night Football has to be a top moment as well.

Maybe the highest of the highs this season came in front of a raucous Arrowhead Stadium on that Monday night in September, when the Chiefs destroyed the AFC's top team and in the process, regained the status as the world's loudest outdoor stadium by breaking the Guinness World Record by hitting 142.2 decibels.

As Chiefs Kingdom dominated their goal that night in the stands, on the field, it was probably the best overall performance by the Chiefs all season as they also won on both sides of the ball against the Patriots.

Tom Brady finished the game just 14 of 23 for 159 yards for the Patriots with one touchdown and two interceptions. It was one of just two games this season that Brady had multiple interceptions, and his rating of 59.9 was the lowest total from him all season.

The Patriots averaged 29.3 points per game this season, but were held to less than half of that against the Chiefs defense that night. It was a thoroughly dominating performance by the Chiefs defense on the biggest stage they had all season.

Offensively, Alex Smith, Knile Davis, Jamaal Charles and Travis Kelce all shined for the Chiefs.

Smith may have had his best game of the season by completing 20 of 26 for 248 yards and three touchdowns.

The Chiefs rushed for over 200 yards in the game led by the duo of Davis (16 carries, 107 yards) and Charles (18 carries, 92 yards, 1 touchdown). The Patriots defense finished No. 9 in the NFL against the run, allowing just 104 yards per game on the ground.

It was also the night the country was introduced to tight end Travis Kelce, who had created a buzz throughout training camp and the first three games of the season, during which he had 10 receptions for 166 yards and one touchdown.

But on this night, Kelce had eight receptions for 93 yards and a touchdown, outshining Patriots tight end Rob Gronkowski, who finished the game with just two catches for 31 yards and a touchdown.

While the Chiefs season didn't end the way everyone would have hoped (with a Super Bowl victory), these five moments stand out as the most memorable.
