The odd thing to me, if CFB had some transparent element of metric/computer, the SEC/BiG powers would do fairly well, most of the time. What's the fear?
They know human voters consistently overrate Big Ten teams (by a lot) and SEC teams (by less but still such) compared to what any good-faith and well-designed computer model would say.
You know the dumb ESPN clichés they use to get around such robust evidence:
"Passed the eye test!" (the ultimate ******** line)
"So much talent!" (if he hits so good then why doesn't he hit good?)
"So much passion in that fanbase!" (code: this is about the money)
"Big wins!" (the computer doesn't think so)
"No bad losses!" (the computer doesn't think so)
"Well, if you look historically..." (nobody ******* cares what happened in 1950)
They could make a transparent poll that is the simple average of a few reputable, independent computer analysts (e.g., Massey, Sagarin, ESPN FPI, SRS, etc.) and let the chips fall where they may. I know there is still a committee for basketball, but that is somewhat close to what they do over there in seeding and setting up the NCAA tournament with the rankings produced by KenPom, Torvik, and the NET rating.
But then they've got nothing to hide behind and have to stand on their own merits.
And that ******* terrifies them. It tells you all you need to know.
