You can dismiss the messenger, or pooh-pooh the message, but this Jeff Schultz column is a checklist of what college football will look at weighing with regards to the regular season if and when (“if”, heh) the postseason expands.
And before you say, “Schultz wants ’em to stop at eight”, keep in mind that he’s proposing they dump conference championship games and up to two regular season games. Every regular season game you eliminate adds another weekly round to the playoffs. My math may be rusty, but I think that would get you to sixteen teams in a playoff with room to spare.
