BTW, if you guaranteed all division winners a playoff spot but seeded by record. the playoff seedings would be:
AFC
Would be exactly the same as it is now.
NFC
1. Seattle
2. Green Bay
3. Dallas
4. Arizona
5. Detroit
6. Carolina
So Dallas as the 3 seed would play the worst team, i.e. Carolina instead of being forced to play a much better team i.e. Detroit and Arizona would be hosting Detroit.
