The Chiefs snapped a six-game home losing streak to the Raiders and have won their first six games of the season for the first time since going 9-0 in 2003.
Linebacker Tamba Hali was named AFC Defensive Player of the Week after recording 3 1/2 of Kansas City's 10 sacks, including two in big spots in the fourth quarter -- on a 3rd-and-2 play to force a punt and a 12-yard sack on first down that pushed the Raiders back to their own 28.
"You can't make the type of mistakes we made against a good football team like this and expect to win the game," said Raiders coach Dennis Allen, who called the stadium "a tough environment to play in."
Kansas City is 2-3 all-time against the Texans.
WHAT TO WATCH FOR
Kansas City is a tough task for any quarterback. The unbeaten Chiefs are the first team in NFL history to start 6-0 after losing 14-plus games in the previous season and will be shooting for their first 7-0 start since 2003 (9-0).
The K.C. defense is coming off the 10-sack performance against Oakland and has helped the team compile an NFL-best plus-12 turnover ratio. Smith, meanwhile, is 25-5-1 as a starter in his last 31 games.
Defense and special teams have contributed heavily to Kansas City's success, accounting for over 46.1 percent of the Chiefs' points so far, including five touchdowns.
"It's something we talked about from Day 1, the scoring," Reid said. "There's equal opportunity in all three phases. We want everybody to have their chance to score a touchdown."
The numbers say the Texans should be nearly as successful as the Chiefs. Houston is allowing an NFL-low 252.8 yards per game and garnering 395.7 yards on offense, good for seventh-best in the league. Turnovers, though, have been the great non-equalizer in this case. Houston is an AFC-worst minus-12 when it comes to turnover ratio and that is why the team is scoring just 17.7 points per game.
"Turnovers get you beat in this league and they're getting us beat on a consistent basis," Kubiak said.
With the QB situation in flux, expect Houston to lean heavily on Foster, who has an AFC-leading 531 rushing yards on the season.
Interestingly the Chiefs, who hardly have an explosive offense, have their own big-time runner in Charles, who is second in the NFL behind Philadelphia's LeSean McCoy with 129.2 scrimmage yards per game.
As a whole Kansas City generates just 326.3 ypg and Smith is more of the a manager-type, who places securing the football above all else.
On the injury front Houston lost starting safety Danieal Manning for the rest of the year due to a right knee injury suffered against the Rams.
The backup quarterback is the most popular guy in any city when the starter is struggling but you have to remember they are usually in that position for a good reason and Yates showed that against the Rams.
Throwing Keenum to the wolves against this Chiefs defense is also unlikely to jump start things for Kubiak, who has piloted the Texans to a 4-8 mark since their 11-1 start to the 2012 season and now seems to be grasping at straws.
