You mean the Chiefs didn't put their defense on the field?
Do the Chiefs have a defense?
Yup. And for all the wailing about the effect of the coin flip - when I ran the numbers a couple of years ago, the win/loss of those getting the ball first in overtime was one game from exactly 50%. Some coaches pick to kick first and they are generally just as successful, since they get each the advantage of their opponent starting deep (and getting the ball on a shorter field if they hold up), knowing exactly what they need to do to counter on the scoreboard, and the luxury of using all four downs.
