With only 4 teams involved there is still going to be a team that gets snubbed and could argue they had a shot. I agree with this playoff idea but part of the problem is the seeding and ranking and this system would still not solve that. The system still wouldn't respect the mid majors that are undefeated and argue they should be on the big stage. To me you have to go at least 8 teams but seeing as 4 is as far as the NCAA will go its better than nothing. However, you will still have a problem with the seeding almost every year. Even March Madness has issues with that every year and by keeping the current system of ranking in football this would be no different.
