I really enjoy the CFP as it exists right now. I think that there are only a small handful of teams that have a realistic
chance to win the natty in any given year. See Georgia/Alabama of last season.
I don't think its necessary to add many more teams because the blowouts in the early rounds will still continue, and we will be left with the same top teams that would have made it in the original 4 team format.
Even in a 12 team format, does anybody expect #12 Pitt to win vs Bama or Georgia? Let alone a 16 team field where #14 Oregon, (who just got wiped off the map by Utah) would be making the field.
I think we should continue to keep the CFP at 4 teams.
