The highest-paid player stood between the other team's star and a touchdown, football's version of one-on-one, and outcomes swing on moments just like this.
The Chiefs used to win some of these. That seems like a long time ago now, doesn't it?
Texans quarterback Deshaun Watson rolled to the left, to Frank Clark's side, and for all the local drama about Clark's pass rushing, this is a spot in which he's excelled. He tackles. He owns his gap, and often a teammate's.
Here, he bounced on his toes around the 2-yard line, staring down one of the NFL's brightest young stars.
Watson chopped his feet, faked for a millisecond to the outside, saw Clark's shoulders inviting him inside and went for it. Clark dove at Watson's hips, just like you're supposed to, making contact at the 3.
But Watson spun on Clark's inside shoulder, slipping through his grasp. He pushed with his legs and landed in the end zone, 10 feet or so from where Clark first hit him.
That touchdown dripped with impact: It was the game's last score, proving to be the winner in the Chiefs' 31-24 failure against the Texans. It exploited perhaps the Chiefs' greatest weakness for four years running now, a quarterback running through an isolated defensive lineman for a score against a team that talked all week about needing attitude and toughness.
"All I (saw) was, 'Be patient, don't miss the tackle and force everything back inside,'" Clark said. "Do your job. That's all I can ever do. Just do my job. (Watson made a) good move, (we) gotta rally. Everybody's gotta rally and make the play."
Frank Clark is being paid $63.5 million guaranteed to make that play. He did cause and recover a fumble on the Chiefs' first defensive snap, but he didn't stop Watson with the game's outcome in the balance, and that's as accurate a micro-representation of the Chiefs' current micro (so far) slump as is possible.
The Chiefs wish that was their only problem.
A team playing the most anticipated season in a generation is currently being straightjacketed by the same old problems, over and over and over again.
Frustration and even some anger is everywhere. As he came off the field, Clark screamed, "We gotta stop the (expletive) run!" Guys shuffled through through the locker room in silence after the loss, heads down. NFL locker rooms aren't usually like this, even after defeats, not with teams that appeared to have crossed the threshold from hoping to play in the Super Bowl to expecting to.
"They're exploiting us," linebacker Damien Wilson said.
What are they exploiting?
"The ability to run the ball, man," he said. "The ability to run the ball. Every team does the same thing."
What's the biggest issue?
"Stop it," he said. "Plain and simple, we gotta stop it."
Is it execution, is it tackling?
"Yep," he said. "Execute. We just have to execute."
Tight end Travis Kelce's patience for diagnosis was even shorter. He answered a few questions as quickly as possible, then left, wishing reporters "a good one."
Locker rooms can divide when a specific unit or even position group is failing the larger mission, but say this for the Chiefs: They've slumped together.
An offense that hadn't scored fewer than 26 points in two years has scored just 43 total in two home losses. An offensive line playing with two backups is giving up consistent pressure, and this is now two weeks in a row where that's contributed to the re-aggravation of quarterback Patrick Mahomes' left ankle injury.
Mahomes and Reid downplay the injury, but it's easy to see a difference. Mahomes' lack of stability impacts his mechanics, mobility and accuracy.
He completed 10 of 16 passes for 189 yards before the play that appeared to bring back the pain _ and three of those incompletions were directly related to being hit as he threw.
After that, he completed just nine of 19 passes for 84 yards.
The Chiefs are playing without starting left tackle Eric Fisher and starting left guard Andrew Wylie. Reid has essentially abandoned the run _ they've run the ball just 25 times total the last two weeks _ and quantifying how much of this is injuries is impossible.
All of that and we're just now getting to the defense, which is surrendering ground at an incredible rate _ 192 yards rushing to the Texans and an average of 190 over the last four games.
That problem has been downplayed in some circles with the logic that time of possession isn't as important as old-school football men believe, but that logic misses the point.
It's not about the clock. It's that every opponent has an easy way to move downfield.
"It's not one person that is the problem," coach Andy Reid said, and you can look at that as a good or bad thing.
Carlos Hyde ran for 116 yards, a total he last reached five teams ago. The Chiefs have given up 5.2 yards per rush this season, meaning the average ballcarrier opposing this team has matched Jim Brown's career efficiency.
The Chiefs are wobbling, then, and the heck of it is that no single player or area is either above criticism or the entire problem.
They are talented enough to scuffle through the remaining 10 games and qualify for the playoffs, but this season has never been about qualifying for the playoffs. They are cracked in so many ways _ both lines, the run defense, route precision, run game and even Mahomes' accuracy and dynamism once his ankle gives.
Panic is inappropriate. No Super Bowl champion has ever been developed in October, and Reid's Chiefs have overcome worse in the past.
But they've never done it with these stakes. This is, almost certainly, the last year they'll have Mahomes on his rookie contract. This should be the time they have the most flexibility, and the most answers. Team-building gets more difficult from here.
One more time: This is not a freakout. The Chiefs have the talent and brains to fix most of their problems, and no team's path through the NFL is linear.
It's just that the good ones are supposed to get better, and the Chiefs are currently getting worse. They have four days before their next game, on the road. It's not so early anymore.
