The Kansas City Chiefs are champions of the National Football League, defeating the San Francisco 49ers in epic fashion to win the Lombardi Trophy for the first time in 50 years.

Here are some interesting notes about arguably the greatest night in franchise history.

1. Head Coach Andy Reid is a Super Bowl champion

Reid was already one of the greatest coaches of all-time prior to Sunday night's victory, but his 222nd career win as a head coach tops them all. For the rest of time, Reid will be remembered as a Super Bowl champion.

His 222 victories rank sixth in NFL history.

2. The Chiefs pulled off yet another incredible comeback

For a third-straight time this postseason, the Chiefs found a way to rally back from a double-digit deficit to not only win, but to win by double-digits themselves. It capped an epic playoff run that's truly one of a kind in the history books.

What made Sunday's comeback all the more impressive, however, is when it took place. The Chiefs trailed by 10 points well into the fourth quarter, and with just over 10 minutes left in regulation, Kansas City had less than a six percent chance of winning the game.

The Chiefs caught fire for 21-unanswered points after that, as Mahomes found tight end Travis Kelce and tailback Damien Williams each for scores before Williams sealed it with a rushing touchdown late. The 21 points were the most by a team in the fourth quarter of a Super Bowl in NFL history as the Chiefs completed what is tied for the second-largest comeback in the 54-year history of the Super Bowl.

The comeback was engineered yet again by Mahomes, whose ability to thrive in these moments is exemplified by his perfect record this season when trailing by double-digits at any point in a game.

3. Mahomes was on another level in the fourth quarter

Despite struggling mightily in the third quarter, Mahomes didn't let interceptions on back-to-back possessions break his spirit. The 2018 NFL MVP completed 10-of-17 passes for 141 yards and two touchdowns in the fourth quarter, leading the Chiefs to touchdowns on their final three meaningful drives of the game.

It was a performance worthy of a champion, and at only 24 years old, Mahomes is the second-youngest quarterback ever to win it all.

And here's more on just how incredible Mahomes' late magic was.

There's also this, which dates back to last postseason.

4. Tyreek Hill's 44-yard reception on third-and-15 was the play that started it all

Amidst all the late fireworks, it's easy to forget that Hill's catch on third-and-15 with just over seven minutes left was arguably the play of the game. The Chiefs truly had their backs against the wall, facing a long conversion and down 10 points with time ticking away.

What happened next will echo throughout Chiefs Kingdom forever. Mahomes, with excellent protection from the offensive line, connected with Hill on a 44-yard pass downfield to set Kansas City up deep inside 49ers' territory and ignite the rally.

Of course, Mahomes is no stranger to stepping up on third-and-long.

5. Damien Williams had a game to remember

Williams, already a postseason star, saved his best work for Super Bowl LIV. The veteran tailback tallied 133 yards of total offense and two touchdowns on Sunday, finding the end zone on the go-ahead and game-sealing scores.

He finished the playoffs with six touchdowns, becoming just the 11th player in NFL history to score six or more times in a single postseason run. His dynamic ability was on full display for the world to see.

6. Frank Clark was legendary this postseason

Clark – who had four sacks already this postseason headed into the game – came up with the biggest defensive play of the contest when he sacked 49ers' quarterback Jimmy Garoppolo on fourth down with just over a minute left, halting San Francisco's drive at midfield with the lead on the line.

It was the biggest play of Clark's impressive career as he became the first player to tally 5.0+ sacks in a single postseason run since Denver Broncos' linebacker Von Miller in 2015.

7. The Chiefs' secondary made some crucial plays in the first half

The epic nature of the fourth quarter makes it easy to forget some critical moments that occurred early in the game but still made a major difference in the end. One of those plays was a touchdown-saving tackle by safety Tyrann Mathieu, who prevented a score on the 49ers' first series of the game when he stopped wide receiver Deebo Samuel from extending a huge, 32-yard rush.

San Francisco only tallied three points on that drive, marking what turned out to be a major difference in the end.

Cornerback Bashaud Breeland also accounted for a big play early, picking off Garoppolo to set up a Chiefs' field goal.

8. Offensive tackle Mitchell Schwartz put together an incredible postseason performance

Schwartz is one of best in the business and it was on full display throughout the Chiefs' postseason run. The skill-position players receive most of the praise, but none of it is possible without guys like Schwartz playing at a championship-caliber level up front.

9. The Chiefs converted multiple fourth downs early

Another element of the game that will likely get lost in the shuffle was the Chiefs' ability to convert two fourth downs early in the contest. In fact, the first - a one-yard rush by Williams on a brilliantly-designed "wildcat" run – set up the Chiefs' first touchdown.

As it turns out, as Offensive Coordinator Eric Bieniemy revealed post-game, the play was inspired by the 1948 Rose Bowl.

Those two fourth-down conversions made some history, too.

10. Patrick Mahomes is the youngest player in NFL history to win both a league MVP award and a Lombardi Trophy

Mahomes is special, that is obvious, but his accolades are piling up at a rate like we've never seen before from such a young player. Simply put, this kind of success is unprecedented.

And, as Super Bowl MVP, Mahomes is the youngest quarterback to ever win the award.

It all helped the Chiefs secure their first Lombardi Trophy in a half-century, rewarding fans across the world with the performance they've long awaited. The Kansas City Chiefs are champions of the NFL, and if Sunday night was any indication, they're just getting started.
