I rate it based on the ratio of white to black athletes they have on the field. It's my interpretation of 'best'.
No, I don't but the point is that there is wrong ways of identifying the "best" team in a preseason ranking and basing it solely on SoS is definitely one of incorrect methods. If someone said that ULM is the #1 team in the country, they'd be just as incorrect as saying 2+2 = 12. Sure, it's an opinion, but some opinions are just wrong.
There is pretty much three ways of doing pre-season rankings:
* Where you think they'll end up.
* The talent you anticipate they will put on the field.
* The "loss" method which is a guess at loss potential
