I have no idea what individual members use to compile their top 6. I know of no committee member that has ever divulged that. Sorry if I intimated that when I quoted the Metrics section. The Metrics section allows them to use a wide variety of data as noted. It only cautions against polls, also as noted.
So what do they use? Road wins? OOC SOS? Opponents winning percentages? Power ratings? SOR? Game control? Vegas odds? Splits? Action Network havoc rate? Sagarin conference ratings? FEI? Massey aggregate? FPI efficiency? DVOA? W-L? EPA? WAR? Eye balls? Magic Eight Ball? Dream sequencing? Seance? Rabbits foot? Whatever. I’m being facetious on some of these obviously. They can use a wide range as noted in the protocol. That’s OK with me.
Once they get those six, the action begins with the criteria.
I think that addresses your major question. What else?
That's the crux of it all.
The CFP process, particularly the sequential ranking and binning, requires subjective decisions about what metrics to use and how to weight those metrics. The overwhelming odds are that more than a few committee members used qualitative, subjective metrics. That process is vulnerable to conscious and unconscious biases.
That easily biased process also ranks the top 6, not just lists them, before considering the tie-breaking criteria.
From the SI article:
3. Ranking step
This is when each selection committee member formally ranks the top-six teams from the listing step. The top-ranked team in each member's poll receives one point. The second-best team receives two points, the third-best three points, and etc.
Not for a second do I believe the committee members all ignore the injury when making that ranking list.
So, if they then find FSU and Bama as reasonably comparable, and go to the tie breaking 5 criteria, they're likely reusing criteria that they had the freedom to initially choose to use directly or indirectly.
I simply reject your argument that the committee must have used a rational, unbiased, quantitative, clearly defined procedure because they arrived at the same conclusion you did.
It seems your procedure was to accept the committee's assertion that FSU and Bama were reasonably comparable and then apply the tie breaking criteria.
I also reject that FSU and Bama have reasonably comparable resumes. I accept that that is a subjective judgment, but find the committee's prior rankings this year and in previous seasons to be inconsistent with those resumes being comparable.
I think the committee talked themselves into believing the resumes were reasonably comparable because that then allows them to point to the injury as the justification they needed to keep the premier program and conference of the last decade in.
