OK then.

I don't know what argument you are trying to make here. Bama's SoS was #10, Wisconsin's was #20. Both were 1-loss non-Champions and the one with the better SoS got in. What do you want?
As far as the list:
- Auburn had a really good SoS but they lost three games.
- Ohio State had a really good SoS but they lost twice including an ugly blowout in Iowa City.
- Oklahoma had a really good SoS and they got in.
- Penn State had a really good SoS but they lost twice.
- Clemson had a really good SoS and they got in.
- Georgia had a good SoS and they got in.
- TCU had a good SoS but they lost three games.
- Notre Dame had a good SoS but they lost three games.
- Iowa had a good SoS but they lost FIVE games.
- Bama had a good SoS and they got in.
Oklahoma, Clemson, and Georgia were obvious. They were all 1-loss P5 Champions with top-6 SoS. After that it gets tough. The other two P5 Champions had two losses each including one blowout each. Ohio State had a better argument than USC because the Buckeyes played a tougher schedule and the Buckeyes were ranked higher. The only other two teams worth discussing were the two P5 1-loss non-Champions. Of those, Bama's SoS was better than Wisconsin's.
If it had been my decision, I would have eliminated USC and Wisconsin. I would have eliminated USC because they were in the same boat as tOSU but with a worse SoS. I would have eliminated Wisconsin because they were in the same boat as Bama but with a worse SoS.
That would have left Bama and Ohio State. I don't have any problem with the committee's decision. The only thing the committee did that ticked me off was that the previous week they stated that #4 through #8 (UW, Bama, UGA, Miami, FL, and tOSU) were all very close. As it turned out, that was obviously untrue. If it had been true then the two of those that won (UGA and tOSU) would have joined Clemson and Oklahoma in the playoff while the three that lost or didn't play (UW, Bama, Miami, FL) would have missed.
Prior to that statement I thought that tOSU's only chance was for TCU to knock off Oklahoma. As it turned out, that was Ohio State's only chance because their statement that Ohio State was already very close to Wisconsin, Bama, Georgia, and Miami, FL was complete BS. In fact there was a big and unbridgeable gap between the 1-loss teams (and Auburn) and the two-loss teams.
