The Kansas City Chiefs lost a thriller to the New England Patriots on Sunday night, 43-40, for their first loss of the season.

Here are nine interesting notes from the game.

1. It was the definition of a shootout in Foxboro

The Chiefs and Patriots combined to score 83 points on Sunday night – tied for the fifth-most in a game this season. It marked the third game in the NFL this year in which both teams scored at least 40 points.

And for Kansas City, much of that scoring took place in the second half.

In fact, the Chiefs' 31 second-half points were their most since Week 17 of the 2009 season and the most that the Patriots had allowed since at least 1991.  

2. The Patriots don't allow 40 points very often, unless they're playing Kansas City

The Chiefs ultimately came up short on Sunday, but they still managed to continue a fairly incredible trend.

Since 2013, New England has allowed 40 or more points just three times in the regular season – and the Chiefs are responsible for all three.

3. Despite all of that scoring, the Patriots came to play

New England played an efficient and effective brand of football on Sunday, as they didn't punt once in the game and weren't charged with a single penalty on either side of the ball.

In fact, according to the folks at Patriots.com, New England is the first team in the Super Bowl Era to play the entirety of a game without a single punt or charged penalty.

4. The game came down to the wire, but Patriots' quarterback Tom Brady came out on top

Brady demonstrated why many consider him the best quarterback of all time on the Patriots' final possession, leading New England on a seven-play, 65-yard drive to set up a game-winning field goal as time expired.

It marked the 200th regular-season victory of Brady's career, making the 41-year-old signal caller just the fourth player – and only quarterback - in NFL history to achieve 200 victories.

Additionally, Brady moved past kicker Adam Vinatieri on Sunday for the most regular and post-season victories in NFL history with 227.

5. Eighteen years Brady's junior, Chiefs' quarterback Patrick Mahomes played pretty well himself

Mahomes completed 23-of-36 passes for 352 yards, four touchdowns and two interceptions on the night – marking the 23-year-old's fourth game this season with at least three passing touchdowns.

Those numbers are impressive on their own, but as Soren Petro of Sports Radio 810 points out, young quarterbacks don't find the end zone often in Foxboro.

6. Mahomes' efforts through the air set yet another record

Kansas City's young signal caller managed to throw for at least 300 yards for a fifth-straight game on Sunday, becoming the first quarterback in franchise history to do so. He's just the second player in the NFL to do so since 2016, joining Aaron Rodgers.

Additionally, it's worth mentioning that Mahomes' 354 passing yards marked a career-high.

7. Those 354 yards helped Mahomes continue what's been the most prolific season by a Chiefs' passer in franchise history

Mahomes now has 1,865 passing yards on the season – the most through six weeks in franchise history by 228 yards. It currently ranks as the fifth-most in the NFL behind only Ben Roethlisberger, Matt Ryan, Jared Goff and Kirk Cousins.

Moreover, Mahomes' efforts have helped Kansas City score 215 points already this season, which is the most through six games in team history.

8. Tyreek Hill and Kareem Hunt had big nights for Kansas City

Hill found the end zone a career-high three times on Sunday night and already has six receiving scores on the season – just one shy of matching his total from all of last year.

The speedy Hill has 27 touchdowns overall in his brief career – tied with Antonio Brown for the fourth-most in the NFL in that span – while averaging a ridiculous 47.4 yards per score.

Tailback Kareem Hunt also put together a strong game in Foxboro, amassing 185 yards of total offense. It was the third-most productive game of Hunt's young career, trailing only performances against New England (246 yards) and Los Angeles (206 yards) in 2017.

Remarkably, in just eight quarters against the Patriots, Hunt has 431 yards of total offense.

The 23-year-old tailback picked up 105 of those yards through the air on Sunday, notching his first-career game with at least 100 yards receiving.

Both Hunt and Hill each surpassed the 100-yard plateau through the air in the game, marking the second time that Kansas City has featured multiple players with triple-digit receiving yards in a single game this season.

Before this year, the Chiefs hadn't accomplished that since 2006.

Furthermore, Hunt and Hill each tallied a receiving touchdown of at least 65 yards in Sunday's game. The two players have combined for four such touchdowns against New England over the past two seasons while the rest of the NFL hasn't recorded a single one.

9. Unfortunately, the Patriots also found success in the passing game

Brady threw for 340 yards in the contest, connecting with four different receivers for at least 50 yards each.

It was a difficult test for a beat-up Chiefs' defense, which was without defensive backs Eric Berry, Daniel Sorensen, Eric Murray and Armani Watts in addition to pass-rushers Justin Houston and Tanoh Kpassagnon in the game.

That meant relying on a crop of young and inexperienced players, but it's a group that Head Coach Andy Reid is confident will improve moving forward.

"It's new growth, and that's OK. The attitude is right, it's just a matter of working through youth and communication. That's what we're doing with the new group in there," Reid said on Monday. "You see them get better as the game goes on – you're seeing that growth right there in front of you with the new bodies and personalities in there. They're battling, though. If they're making a mistake, it's at 100 miles per hour, but they're working through it."
