In any case, I support the only conscionable solution, which is no playoff at all and a return to college football the way it was before it was sullied by the Bowl Coalition. I have no interest in finding the best team. The best team is in the NFL. If I wanted one single winner I would watch the Super Bowl. I watch college football because of the traditional place it holds in my (our) culture, and I expect it to respect that tradition.
You'll have to go back to the 1920s to find a time when there wasn't a "national champion" declared every year. At least with a playoff the champion earns it, rather than just having it bestowed upon them by lazy, biased voters.
There wasn't a national champion, there were many. I think every team that feels like it deserves it should claim a national championship, because I don't care and the fact that people do care is ruining football.
