Ok. You believe what you want, but the NFL for many years now (since the advent of 32 teams) has a set rotation schedule, which is very simple to understand:
six games against division opponents (one home, one away)
four games against a rotating division within your conference. For the Chiefs, it's the AFC North this year and the AFC South next year.
Four games against a rotating division in the other conference. For the Chiefs, it's the NFC West this year and the NFC North next year.
The remaining two games are against the two teams in (1) the other divisions in the same conference that you aren't already playing this year (2) that finished with the same seed in their division as you finished in yours in the prior year. For the Chiefs, that means that if you finish first in the AFC West, next year you will play the team that had the first seed in the AFC East and North next year (because you are playing ALL of the AFC South next year.
AND HEY, GOOD NEWS -- if you finish first and the Patriots finish first too, then next year you get to come back to Foxboro AGAIN.
And whine that you're being ****ed and the NFC is rigged!! Because you don't understand that it's a system. Whether you believe in it or not.
