Honestly, looking back at the 2018 KC Chiefs schedule, it feels like staring at a blueprint for the modern NFL. Most people remember 2018 as the "Year of Mahomes," but the schedule itself was a brutal gauntlet that almost broke a young quarterback before he even got started.
Think about it.
The Chiefs weren't favorites. They had just traded away Alex Smith, a reliable veteran who had led them to back-to-back AFC West titles. In his place was a kid with a voice like Kermit the Frog and a throwing arm that scouts said was "erratic." The schedule-makers didn't do him any favors. Kansas City opened with two road games against divisional rivals and perennial contenders.
It was a trial by fire.
Opening Salvos: Chargers and Steelers
The season kicked off on September 9, 2018, at StubHub Center. If you remember that game against the Los Angeles Chargers, you remember the moment the league realized something was different. Tyreek Hill took a punt return 91 yards to the house in the first quarter. But it was Mahomes throwing for 256 yards and four touchdowns—including a shovel pass that looked like a glitch in the Matrix—that set the tone.
The 2018 KC Chiefs schedule then sent them to Heinz Field. Kansas City hadn't won in Pittsburgh since 1986. Think about that for a second. Over three decades of futility wiped out in one afternoon. Mahomes threw six touchdowns. Six. He was basically playing a video game while the Steelers' secondary was stuck in slow motion.
The final score was 42-37. It revealed the recurring theme of the 2018 season: the Chiefs' offense was a supernova, and their defense was a screen door in a hurricane.
The Mid-Season Reality Check
Success wasn't a straight line. By the time October rolled around, the league started to catch up, or at least they tried to. On October 1, the Chiefs traveled to Denver for Monday Night Football. This was the "left-handed pass" game. Facing a fierce pass rush from Von Miller, Mahomes scrambled left and, with a defender draped over him, tucked the ball into his left hand to convert a third down.
They won that game 27-23, moving to 4-0.

But then came the New England Patriots.
October 14, 2018. Sunday Night Football at Gillette Stadium. This was the first true Mahomes vs. Brady showdown. It lived up to every bit of the hype. The Chiefs fell behind 24-9 at halftime. Most young QBs would have folded. Instead, Mahomes exploded in the second half, leading the team to 31 points. They ultimately lost 43-40 on a Stephen Gostkowski field goal as time expired.
It was a loss, sure. But it was also a message. The Chiefs could go toe-to-toe with the dynasty in their own house and nearly win.
Breaking Down the Home Stretch
The middle of the 2018 KC Chiefs schedule featured a lot of Arrowhead magic. They dismantled the Cincinnati Bengals 45-10 and outlasted the Arizona Cardinals.
Then came Mexico City. Or, well, it was supposed to be Mexico City.
The November 19 matchup against the Los Angeles Rams is widely considered the greatest regular-season game in NFL history. Because of poor field conditions at Estadio Azteca, the game was moved to the Los Angeles Coliseum on short notice.
It was a shootout for the ages.
- Final Score: Rams 54, Chiefs 51.
- Total Yards: Over 1,000 combined.
- The first game in NFL history where both teams scored 50+ points.
Kansas City left that game at 9-2. They were exhausted, battered, but clearly the most dangerous team in the AFC.

The Hunt for the Number One Seed
December is where seasons are made. The Chiefs had a target on their backs. They faced a gritty Baltimore Ravens team on December 9. This was the "fourth-and-nine" game. Mahomes, rolling right, threw a cross-body laser to Tyreek Hill to keep the drive alive. They won 27-24 in overtime.
However, the schedule had one more twist. A Thursday night loss to the Chargers at home (29-28) and a road loss to the Seattle Seahawks (38-31) suddenly put the AFC West title in jeopardy.
Everything came down to Week 17 against the Oakland Raiders.
It wasn't even close.
The Chiefs rolled 35-3. Mahomes joined Peyton Manning and Tom Brady as the only quarterbacks to throw 50 touchdowns in a single season. They secured the #1 seed. They secured home-field advantage. They secured a bye.
The Heartbreak of the AFC Championship
The 2018 KC Chiefs schedule concluded with two playoff games at Arrowhead. First, they finally exercised their home playoff demons by crushing the Indianapolis Colts 31-13 in the Divisional Round. It was snowing. It was loud. It felt like destiny.
Then came the rematch with New England.
January 20, 2019. The AFC Championship.

The game was a defensive struggle early, then a chaotic explosion late. The Chiefs didn't score in the first half. They trailed 17-7 going into the fourth quarter. Then Mahomes went off. He led three touchdown drives in the final period.
But then, the play.
Chiefs linebacker Dee Ford was lined up offsides on a play where Charvarius Ward intercepted Tom Brady. The interception was nullified. Brady took advantage, the Patriots scored, and although the Chiefs forced overtime with a Harrison Butker field goal, they never touched the ball again. The Patriots won the toss, marched down the field, and won 37-31.
Why This Specific Schedule Matters Today
If you look at the 2018 season in a vacuum, it’s a story of "what if." What if Dee Ford isn't offsides? What if the coin toss goes the other way?
But the 2018 KC Chiefs schedule did something more important than winning a Super Bowl that specific year. It provided the data points Andy Reid needed to build a dynasty.
- Defense overhauls: The inability to stop Brady in overtime led to the firing of Bob Sutton and the hiring of Steve Spagnuolo.
- Mahomes' Maturity: He learned he could lead a comeback against anyone, anywhere.
- Arrowhead Identity: The stadium became a fortress again.
Actionable Takeaways for Football Historians and Fans
If you're looking to revisit this season or understand the roots of the current Chiefs' dominance, here is how to process that 2018 data:
- Watch the Raiders Week 17 highlights: It shows the peak of the "Legion of Zoom" offense before the league started playing exclusively "two-high" safeties to stop them.
- Study the Rams game film: It’s the best example of how the NFL transitioned into a truly pass-first league where defense became secondary to explosive play rate.
- Check the injury reports from the Seattle game: It explains why the Chiefs struggled with depth late in the season, leading to their current philosophy of drafting heavily for rotational defensive linemen.
The 2018 season didn't end with a ring, but it ended with the birth of a legend. Every game on that schedule was a brick in the wall of what would eventually become three Super Bowl titles in the years that followed.
To truly understand the Chiefs of 2024 or 2026, you have to start with the 12-4 record of 2018. It wasn't just a schedule; it was an evolution. For fans looking to track current team performance against these historical benchmarks, the best move is to compare Mahomes' current "Time to Throw" statistics against his 2018 numbers. You’ll see a player who has traded some of that 2018 recklessness for a surgical efficiency that makes the current version of the team even more dangerous.
Reviewing the game logs from the 2018 KC Chiefs schedule remains the best way to appreciate just how high the ceiling is for this franchise when the offense is clicking on all cylinders.
