The Chiefs/Dolphins game in November is going to be very interesting, if everyone is healthy. Miami is hitting on all cylinders right now on offense, but KC's defense (especially the secondary) is much improved this year, and only getting better.
EDIT: since some scruffy looking nerf herder's got laughs today, here's KC's defensive stats.
YPG: 6th
PYPG: 6th
RYPG: 11th
PPG: 4th
If we want to get in the weeds, we can, but thus far, it's a much improved unit.
