1.) The best four- which should incorporate upside and who is playing their best at the end of the season. We care way too much about some loss in the middle of the season when we make it a season trophy.
2.) The playoff committee.
3.) Because a one game sample is worthless. 18-22 year olds have variance in play, and only needing to get up for a fraction of your games is a big advantage of the G5. I don't care if one team went undefeated and passed their couple hard games while the other got upset. Go with the team that is better. Cincy is not better than Ohio St.
4.)Too much human bias towards this being about deserving rather than who are the best 4 when at their best is why Cincy is in imo. A model like Sagarin had them 6th and Bama 1st. A committee allowed to forget anything but who do you think has the best chance to beat #1 should be in.
Way too much emphasis on record in college football. In the NFL, teams like GB's 2011 super bowl team or Tampa's team last year wouldn't even make the playoffs. Yes, that adds value to the season, but it makes for a bad postseason.
