The Kansas City Chiefs punched their ticket to Super Bowl LV on Sunday night as they successfully defended their AFC title with a victory over the Buffalo Bills.

Here are 10 interesting stats and notes about the win.

1. Patrick Mahomes was at his best once again.

Mahomes completed 29-of-38 passes for 325 yards and three touchdowns on Sunday, tallying his fourth career postseason game with at least 290 passing yards and three touchdowns without throwing an interception. The 25-year-old Mahomes is now tied with Tom Brady and Aaron Rodgers for the must such games in NFL history despite playing in just seven postseason games during his young career.

The reigning Super Bowl MVP now owns the NFL record for touchdown passes (17) through a player's first seven career playoff outings and he once again found a way to lead the Chiefs out of an early hole.

In fact, Mahomes is now 4-1 in his postseason career when trailing by two scores.

Mahomes is also one of just four quarterbacks in NFL history to reach the Super Bowl multiple times within just four career seasons. Additionally, when the game kicks off, he'll be the youngest quarterback in NFL history to start multiple Super Bowls.

2. Travis Kelce had a monster performance.

Kelce turned in yet another big game on Sunday, hauling in 13 receptions for 118 yards and two touchdowns. His 13 grabs matched the NFL postseason record for catches by a tight end in a single game while setting a new mark for receptions by any player in a conference title game.

The veteran pass-catcher also now has 1,643 receiving yards on the year, breaking the NFL record for receiving yards in a single season by a tight end (including the playoffs).

Remarkably, Kelce now has at least seven catches in 10 consecutive games – the second-longest single-season streak in NFL history (including the playoffs).

3. Tyreek Hill was a big-play machine.

Hill racked up nine catches for 172 yards in the victory, picking up a big chunk of that on a 71-yard reception that later led to a 1-yard touchdown connection between Mahomes and Kelce.

The catch marked Hill's 34th reception of at least 40 yards in his career, which are the most in the NFL during that span and 11 more than second place (including the playoffs). It was Hill's sixth career grab of 70+ yards, which are also the most in the league during his time as a professional.

Overall, Hill's 172 receiving yards on Sunday were the most by any player in a single postseason game since 2016.

4. Mecole Hardman made up for his early fumble with some big plays.

Hardman muffed a punt in the opening minutes of the game that Buffalo recovered and turned into a touchdown, but he quickly made up for his miscue with some game-changing plays.

First, the second-year receiver caught a 3-yard touchdown on the Chiefs' very next possession to get Kansas City on the board. Then on Kansas City's ensuing series, Hardman took an end around for a 50-yard gain to set up the Chiefs' eventual go-ahead score.

The rush was the longest in franchise postseason history, breaking the mark held by Priest Holmes (48 yards) set during the 2003-04 postseason.

5. Darrel Williams and Clyde Edwards-Helaire each found the end zone.

Williams found the end zone just a few snaps after Hardman's 50-yard rush, as the third-year tailback powered ahead for a 6-yard score to put Kansas City in front. Williams finished the game with 61 yards from scrimmage (52 rushing, 9 receiving) on 14 touches, with his 9-yard grab converting a fourth down on the Chiefs' first scoring drive.

The former undrafted free agent signee has been crucial for the Chiefs during their playoff run, tallying 155 yards from scrimmage while making some big plays in both games.

Edwards-Helaire, meanwhile, returned to action for the first time since Week 15 and was responsible for the Chiefs' third touchdown of the night with a 1-yard score.

6. Overall, the offense operated with tremendous efficiency on Sunday.

After going three-and-out on their opening series, the Chiefs scored on every one of their offensive possessions throughout the remainder of the game (excluding two drives that ended with kneel downs).

In fact, after falling behind, 9-0, to begin the contest, the Chiefs rallied off 21 unanswered points as part of a 38-6 run that essentially put the game away.

It's part of a larger trend, too. In two playoff games this year – and despite losing Mahomes for nearly half of the Divisional Round – the Chiefs have punted just once this postseason.

7. The defense put together a game to remember.

The Bills entered Sunday's game with the top scoring offense in the NFL since Week 7, but with the exception of Buffalo's early touchdown following Hardman's fumble, the Bills didn't find the end zone again until four minutes remained in the game and the contest was out of reach.

Kansas City held Buffalo – the top third-down offense in the NFL – to just 5-of-14 on third down and 2-of-5 in the red zone in terms of touchdowns, preventing the Bills from ever getting going offensively.

A key example of that defensive success occurred on the Bills' final drive of the first half (when they drove to the Chiefs' 3-yard line) and their opening possession of the second half (when they drove to the Chiefs' 8-yard line. Buffalo marched inside the Chiefs' 10-yard line on back-to-back possessions, but they came away with only six total points combined on the two drives.

The defense was also impressive during the Chiefs' 21-point explosion in the second quarter. While Kansas City chipped away at and ultimately overcame the Bills' lead, the defense held Buffalo to just one first down and a net total of negative four yards on their two offensive possessions sandwiched by the Chiefs' first three touchdowns.

8. Frank Clark and Chris Jones, in particular, were living in the backfield.

A big reason why the Chiefs had so much success defensively on Sunday was due to their pass rush. According to Pro Football Focus, the Chiefs pressured Bills' quarterback Josh Allen on 24 of his 58 dropbacks, with defensive tackle Chris Jones recording seven of those pressures all by himself.

Elsewhere, ESPN's advanced metrics marked it as the top pass-rushing performance in a postseason game since the company began recording this kind of data.

The traditional stats were impressive, too. Defensive end Frank Clark recorded two sacks while the defense as a whole recorded four sacks and 10 quarterback hits.

9. Coach Reid tallied another postseason victory.

Reid's incredible resume grew a bit more impressive on Sunday, as he moved into a tie with Joe Gibbs for the fourth-most postseason victories by a head coach in NFL history (17). Reid ranks two wins shy of matching Don Shula for third on the list.

10. It all helped the Chiefs secure a second-straight AFC title.

Kansas City is heading back to the Super Bowl, which is no small feat in its own right. Only the New England Patriots (2003-04, 2016-18) had successfully defended an AFC title the following season since 2000 until the Chiefs managed to do so this season.

The Chiefs will now look to finish the job in a couple weeks against the Tampa Bay Buccaneers, and if they can pull it off, they'll become the first team since that 2003-04 Patriots squad to win back-to-back titles.
