Titans v Chiefs- 26-7 Chiefs win by a margin of 271%.
The Broncos win by an average marginal percentage of 81%, the Chiefs by 370%. I included the best and the worst percentages so that there could be no whining and moaning from the detractors. Slice it up any way you want, the Chiefs win by a higher percentage. They do so because of the best defense in the NFL. The Broncos have never held a team to single digits, and only one to under twenty. Two teams scored 16 on the Chiefs (Eagles, Cowboys) and one of those teams scored 48 (Cowboys).
So the Broncos can't play defense. Thats good for the Chiefs, as the offense has struggled. The Chiefs play stifling defense. Is it enough to stop the Broncos? I say yes.
