I still don't understand how College football is the only sport that a conference/division champ is not automatically in the playoffs. Even if a 13-20 college basketball team wins their conf tourney, they are into the tournament and no one really cares.
This next part is my opinion and the only reason it will never happen is because of money.
To "fix" the playoffs, have only the FBS conference champs make the playoff with the 2/4 lowest ranked champs have a play in game to get to 8 teams. If a team that did not win their conf feels slighted cuz a team from the sunbelt is in and your not, well to bad, win you conference. if you think this is unfair, move to another conference from say the sec to the Sunbelt or AAC or whatever and just absolutely dominate and get into the playoffs easily. this might actually make conference small again and not try to shoehorn all the "best" teams into one or 2 conferences. Of course with TV deals, teams will not want to go to a lesser conference and lose out on the tv money. of course, if the ncaa was smart back in the day, they would have done the TV deals for all of CFB and this might have kept all these from happening but not sure if the ncaa could have legally done this. Either way, none of this will happen cuz of money
