I in no way ever want to see an 8 team playoff and frankly it wouldn't work.
1. 5 conference champions in. So let's look at this one. Say we had this now, how do you determine a conference champion without a game? Best record? That would not matter as teams don't play the same teams. Say Tech is 11-2 and Florida State is 11-2, and they didn't play each other, who is the champion?
2. Why should the Group of 5 ever get a spot. They don't play near the level of competition. Yes, UCF beat Auburn in a bowl last year, but that's because the SEC has a tendency to not want to show up to bowl games if it is not for the championship.
3. Two at large, well that is subjective as well. Take my 1 and some one decides Florida State is the Champion. And say in the SEC, LSU is 11-2, Auburn is 11-2, Michigan is 11-2, Texas is 11-2 and none are champions. Now pick.
4. What if we keep the conference championship games and move to 8. Then let's say a 11-1 Clemson plays an 8-4 Georgia Tech and Tech wins. Clemson could be out.
Frankly this is all destroying the tradition of the game. It will not be long before they say every team must play 10 conference games. Then we will see the end of Tech-UGA, Clemson-SC and Florida St. Florida.
I say go back to bowl tie ins and crown a mythical champion, because frankly that is what we have now.
