All big 4 conference winners and top rated G5 team get an automatic bid to the CFP. The seeding would be by their standing. If a conference champ or G5 winner is not in the Top 4 standing. They would get a first round home game vs an automatic bye. The max that any conference can have is 3 teams. Any # 2 team not in the sec or big ten would normally be equal to or better than a #4 team from the sec or big ten. Just my opinion.
