Time of possession really doesn’t matter. It’s an overrated stat. What’s more important is scoring points and playing with a lead. That being said, playing against the Chiefs is different. The only team to go arm v. arm against them and win were the Rams on Monday Night Football that changed football forever, but didn’t change football forever. They also had five turnovers that game. To beat the Chiefs you have to limit them to less than eleven possessions or so and have the ground game mash up their linebackers.
Houston did exactly this.
