Wow, you're REALLY bent out of shape.
I will say this....KC had a BIZARRE record breakdown...
4-0 against the NFC
4-2 in their own division [which ultimately got them into the playoffs, Denver was 3-3]
1-5 in AFC games outside their division [including 0-4 against the AFC North], and that 1 win came at the end against Jax
I wonder if any team ever made the playoffs with an out-of-division conference record of 1-5. Not something I feel like researching, but I'd be surprised if it happened more than once or twice.
