Texans are a better team than the Chiefs even despite missing Joe Mixon and Tank Dell. Texans will beat the Chiefs by 10 points maybe.
Texans haven't beaten the Chiefs by more than one score in almost two decades. Your team is not better, and neither is your coaching staff. We're sitting at 9th currently in terms of points allowed, and 8th in points scored. Texans are 11th worst offense.
