The Kansas City Chiefs defeated the Los Angeles Chargers, 22-6, on Sunday to remain perfect on the year.

Here are some quick notes from the win.

1. Tailback Ken Walker topped 100 rushing yards for the fourth time in five games.

Walker continued his torrid start to the season on Sunday by rushing for 128 yards and two touchdowns on 19 carries. Notably, Walker rushed for 53 yards and two touchdowns vs. stacked boxes on Sunday (meaning defenses with eight or more defenders in the box). His 183 rushing yards and six scores this season against stacked boxes lead the league.

The veteran tailback now leads the NFL in rushing yards (665), rushing yards-per-attempt (6.3), rushing yards-per-game (133.9), rushes of 20+ yards (7), and broken tackles (52, per Next Gen Stats), as well.

He's also one of just four players in NFL history to rush for 660+ yards and six or more touchdowns through a team's first five games, joining Terrell Davis (1998), Jim Brown (1958, 1963) and O.J. Simpson (1973, 1975).

Additionally, Walker is one of just two players since the AFL-NFL merger to score multiple touchdowns in four of his team's first five games to begin the year, joining Calvin Johnson (2011).

2. Kansas City is 5-0 for the third time under Coach Reid and Patrick Mahomes.

The Chiefs are undefeated through five games for the third time under Head Coach Andy Reid and quarterback Patrick Mahomes, making them just the fourth head coach and quarterback combination to do so in league history.

The only other duos to achieve that feat prior to Reid and Mahomes were Bill Belichick and Tom Brady (4 times), Tony Dungy and Peyton Manning (4 times), and Bud Grant and Fran Tarkenton (3 times).

Kansas City is the lone remaining undefeated team in the AFC, and one of just three left across the NFL.

3. Patrick Mahomes earned his 100th career regular-season victory.

Mahomes earned his 100th career regular-season victory on Sunday in just his 131st start, matching Tom Brady for the fewest starts to 100 wins in league history.

Mahomes' 272 passing yards on Sunday were his second-most in a single game so far this season, trailing only his 382 passing yards against Indianapolis in Week 2.

4. Wide receiver Xavier Worthy had a strong day with seven receptions.

Worthy caught seven passes for 73 yards on Sunday, setting season-highs in both categories. It would have been more, too, had the bulk of a 33-yard reception on the first play of the game not been wiped away due to a penalty.

The third-year receiver hauled in catches of 15 yards, 17 yards and 19 yards over the course of the game as part of one of his top statistical performances as a Chief. Specifically, Worthy made a key catch-and-run (the 19-yarder) that set up a 50-yard field goal in the closing seconds of the first half.

5. Wide receiver Andrew Armstrong hauled in the first catch of his career.

Armstrong, who was elevated from the practice squad for Sunday's game, tallied the first regular-season reception of his career with a 13-yard catch late in the second quarter.

The preseason standout recorded 42 offensive snaps and nine special teams snaps over the course of his first regular-season action as a professional.

6. Kansas City forced two takeaways defensively.

The Chiefs notched a pair of takeaways on Sunday, forcing multiple turnovers for the fourth time in five games. Only the Pittsburgh Steelers, with multiple takeaways in five games, have done so more often.

Linebacker Jack Cochrane was responsible for the Chiefs' first takeaway with an interception early in the second quarter. Cornerback L'Jarius Sneed then forced a fumble in the fourth quarter, which linebacker Drue Tranquill pounced on, for Los Angeles' second turnover.

7. The defense racked up four sacks on the day.

The Chiefs had generated a strong pressure rate in recent weeks, but over the last three games, Kansas City didn't have a sack to show for it. That changed on Sunday.

Kansas City wrestled Chargers quarterback Justin Herbert to the ground on four occasions over the course of the game as defensive end Ashton Gillotte (1.0), defensive end George Karlaftis (1.0), safety Chamarri Conner (1.0), defensive tackle Chris Jones (0.5) and defensive tackle Peter Woods (0.5) all contributed to that effort.

8. Defensive end George Karlaftis leads the NFL in pressures since Week 4.

Karlaftis racked up eight pressures on Sunday after tallying 11 pressures back in Week 4, and now – despite not playing in Week 5 due to the bye – he leads the league in that category since Week 4 with 19 total pressures (according to Pro Football Focus).

As a team, the Chiefs pressured Justin Herbert on 17 of 44 dropbacks (38.6%) during Sunday's game.

9. Linebacker Nick Bolton now owns the franchise record for 10+ tackle games.

Bolton recorded 11 tackles on Sunday, marking the 26th game of his career with double-digit tackles. That total moved him out of a tie with Chiefs all-time leading tackler Derrick Johnson for the most such games in franchise history.

The veteran linebacker ranks eighth in the NFL in that category since 2021.

10. The Chiefs moved to 3-0 in the AFC West this season.

Kansas City is now 3-0 vs. the AFC West through just six weeks, joining the San Francisco 49ers (3 wins) for the most victories against divisional opponents for any team so far this season.

The Chiefs own a 39-12 record vs. the AFC West since 2018, which marks the best record for any team against their own division in that span.

A 5-0 record now secured through the first six weeks of the year, Kansas City will aim to stay perfect this upcoming weekend with a prime-time showdown against the Seattle Seahawks on deck.
