Playing the Texans was the worst thing to happen to them. Probably gave them a false sense of confidence.
They never been that good though. Just riding on the high of a win streak but the blueprint has been well known. How do you beat the Chiefs? Limit turnovers and jump out to a lead. If you got that, you're good. They win one way, that's it.
5 turnovers last game and they still couldn't shut the door until the 4th quarter.
