None of the above.
Playoffs are like standardized tests. Doesnt matter how your year went, just matters how well you can do in a specific setting, in this case the post season.
Yay we get 4 important games at the end of the year. But now none of the regular season matters because 8-4 Bama is still going to make a 12 team playoff. I would rather fix the regular season. Or at least make some distinctions like Basketball does. Regular season champs, vs tournament champs.
People always talk about preferring the good old days where rivalries matter, so let's focus on the conference championship, and not the post season championship.
