The only way one can come to the conclusion that Baylor should get the nod over TCU is to focus on one game and ignore every other game played this season. Why play the games if you're going to ignore every result except the one that seems to support your point. I remember when Appalachian St. beat Michigan, and Stanford upset USC as 41 point dogs in 2007: but to conclude what team is better based on only one game seems absurd. There is no need to castigate TCU for losing by three on the road to a team the caliber of Baylor, while at the same time minimizing a fourteen point loss on the road at 7-5 West Virginia. If you sincerely feel that others are biased in their assessment of the relative strengths of the teams, then consult something like the "College Football Ranking Composite" as compiled on the Massey Ratings site. The 115+ computer rankings and polls place TCU at #3 and Baylor at #8. It would be difficult to argue that there is some 'agenda' involved with the results there. Good luck in coming to terms with the way this season has played out for your team. It has not been a stellar one for mine.
Look, I do not care one iota about Baylor, there are not my team. If Baylor beats KSU it does not seem absurd to focus on one game when they played the exact same conference schedule and both have the same record.
If this was last year and Baylor beats KSU, guess who is getting the auto bid to a BCS bowl? Not TCU.
If the playoffs go to 8 teams and the power 5 gets auto bids guess who would get the auto bid to the 8 team playoffs? Not TCU.
Why should it be any different this year? If the Pats and Broncos finish with the same record in the AFC this year who gets home field adavntage? Is there even an argument in that case and they even played completely different schedules but guess what, the Pats won the head to head game, so they have the advantage. No committee, no computer points, it was settled on the field and nobody even debates that fact.
Comparing Appy State to UM is ridiculous in this situation and an apples to oranges comparison. If in that year, Appy State played the exact same conf schedule as UM and they finished with the same record, then yes, on the field, Appy State was a better team than UM.
You cannot even make the case that Baylor had an easier unbalanced conf schedule like they do in the B10, SEC and Pac12 and may miss some good crossover teams. They played the exact same 9 teams in conference.
Again, the playoff should not be about the best team on paper but who played best on the field of play and there is no better way to prove it than head to head if they have the exact same schedules like in every other sport in the world except possibly FBS football.
