I totally agree that if the TCU/Baylor resumes were swapped with OSU, OSU would still get in. I just don't agree when people say ISU's only chance to get in is to be 13-0, as they'll take a 2-loss non-champion Big 10 or SEC team and use that as some example that the committee is off its rocker. That was NOT an obvious selection between those three, and there were legitimate arguments for all three. I think they made the wrong selection, but I can understand it. People can bag on the CFP all they want, but they pretty much have gotten it right every year, and the worst anyone can point to is the selection of a 12-1 team with a loss over an 11-1 team with similar SOS. Bottom line is since 2017, the CFP has loved ISU. ISU has consistently been the highest or second-highest team given its number of losses. Maybe that love stops this year and in a tight decision the committee goes with somebody else. But so far everything the CFP has done suggests that a 12-1 conference champ in the Big 12 is probably getting in.
In general I think most of us agree that they need defined criteria and ditch the eyeball test. The best argument against the eyeball test was maybe 2007, when overwhelming consensus was that Ohio State and Michigan were the two best teams. Florida edged out Michigan to play in the title game, and for the most part all of the talking heads were of one of two thoughts 1. Michigan and Ohio State are the best two teams, so they should play for the NC, even though they just played; or 2. Michigan and Ohio State are the best two teams, but since Michigan just lost to OSU, they had their chance, and we don't really need to see a rematch.
By a razor thin margin, Florida got in, then proved that Ohio State didn't even belong on the same field.
