Yes 16 is what all G5s want and most P5s but I don’t see that number happening. Sixteen would be a shock to the CFB system. They have never made such a radical change.
CFB normally makes small incremental changes and the old guards are afraid of trying something so different.
The article says they have 63 scenarios but I’m sure they’ll select one of the easiest ones with 6-8 teams. We have to hope they will do the right thing and have a guaranteed G5 with 8 teams.
If some kind of miracle happens and the smarter heads prevail and they decide on 16 teams, there is no need for a guaranteed G5 spot.
