I vote for a 10 team playoff where the bottom four play into a group of 8. So 6 teams get a bye with four playing for the 7-8 slots.
The only way a team that doesn’t win their conference can get in is through the four team “wild card match up”
So this year you’d have potentially Auburn, Wisconsin, Ohio state, and Alabama playing each other to get in.
The top 6 would be a mix of the rest of the top 10 or so.
That way you aren’t totally out if you just happened to be in the tough division of your conference.
Of course nobody is asking me so...
