The major change in the playoffs for next year needs to be doing completely away with rewarding conference champions and expand to 16 teams so everyone plays week 1.
The five champions will be in regardless, but the seedings need to be based solely off the overall rankings. The rankings need to be done off a compilation of different poll ranking/power rankings/rating services etc so it's not just people choosing who they like. No "guaranteed" spots for the SEC & Big 10, just simply based off a comprehensive ranking system.
