If you could combine those two teams....KC's defense and Denver's offense....There wouldn't be much you could do against them boys...
In other words, both teams are kinda one dimensional...but Denver gets a slight edge overall because their offense is so potent. They can let a team like Dallas run up the scoreboard and not worry about it too much.
KC just keeps the other team from scoring much because their defense is pretty dominant against the pass and the run....I mean, look at their points allowed so far this year. They're a top notch D with a boring offense.
