"All in all, we made way too many mistakes today," Chiefs coach Andy Reid said after the game. "You can't do that against good football teams, and that's what the (Houston) Texans are. You give them that many opportunities, and you're not going to win the game.
"My responsibility as a head coach is to play more disciplined football than what we displayed there."

"I saw the replay and I didn't think it was taunting, to be honest," teammate Eric Berry said. "I heard some things being said when the call was made that I didn't agree with, from another side, another party. So if you're going to call it both ways, call it both ways. I've seen worse, I'll put it like that. I've seen worse."
"You've got to live with that with Marcus," safety Ron Parker said. "He loves the game so much. He just leaves everything out on the field and us guys in the [defensive backs] room, we understand that. We won't have a better person in our [secondary] than Marcus, just the way he loves the game and the way he carries himself out there. It's great. He made two interceptions and he bounced back, so I think he did a good job of playing football."
One other way the shaky line play hurts the Chiefs: Smith had that look again, where you can see he’s not trusting the protection. Nervous feet in the pocket, rushing his reads, no confidence in allowing the play to develop.
I’m so confused by Marcus Peters, cornerback for the Chiefs. Sunday’s game against the Texans started and he quickly gave up a 50-plus-yard pass, which was bad. But then he snagged an interception at the goal line, which was great. But then he gave up a 25-plus-yard pass for a touchdown, which was bad. But then he prevented a big pass from being completed, which was good. But then he got called for taunting after wagging his finger at receiver Will Fuller, which was bad. But then he made a second interception, which was great. And all of this happened just in the first half. I’m so confused by Marcus Peters, cornerback for the Chiefs.
While Tyreek Hill sped upfield, pumping his body toward the end zone at warp speed for a potentially momentum-turning score, the yellow flag flew through the air, standing out on the plush green carpet at NRG Stadium like a sore thumb.
Holding penalty on the Chiefs. It’s coming back.
The Chiefs had hoped they could lean more on their offense this year. They were able to last week against the Chargers because of one glorious quarter. But that's about all the Chiefs have accomplished offensively this season.
"I'm not denying the ability is there,'' Reid said. "We have a chance to be a pretty good football team, but we've got to learn from this here.''
Kansas City Chiefs running back Jamaal Charles is out for Sunday's game against the Houston Texans. He is expected to make his season debut in Week 3, a source told ESPN's Adam Schefter.
Hopkins said he loves to go against cornerbacks who are as good as Peters.
"Peters is a great football player," Hopkins said. "I love going up against him. I look forward to matchups going up against big corners like him. He's a Pro Bowl-caliber DB."
It bounced out of bounds at the 1, and the penalty allowed the Texans to start at the 40.
The Chiefs' kickoff coverage had been part of a solid dayfor the special teams, downing the Texans at the 16 and 15 on previous kickoffs.
But this error gave Houston excellent field position, and the Texans marched for a field goal that provided a two-score lead.
"Awful kick, my fault," Santos said. "I've been working to get aggressive with my directional kicks. But I yanked it."
