It will be 8.
5 spots for the Power 5 conference champs and 3 at-large, which will take care of Notre Dame, an at-large for a non-P5 school that is undefeated, and leaves a spot for a non-champion P5 school that only has 1 loss and is considered better than other P5 champions.
And I have no problem with making the round 1 games hosted by the higher seed. More incentive to finish in the Top 4.
Wholeheartedly agree. I want all 5 of the P5 champions guaranteed a spot. I also want a spot reserved for the highest rated independent or lower conference team. That leaves the final two spots to the best at-large teams. I also agree with the first round being hosted at the home stadium of the higher-seeded team. This looks like the best balance of rewarding excellence (P5 champs assured a spot, home field advantage in round one for the best) , not leaving out deserving teams that took a loss because of various unavoidable factors (star player(s) injured, strange game because of rescheduling for whatever reason, early season mental lapse, etc). It also assures the lower conference teams that they have a real shot at the title (even if they are routinely the 8 seed).
Side note: I believe that you have to work in a few basic rules to clean up the selection. I would be in favor of saying that no conference can occupy more than 2 of the 8 spots.
I would also be in favor of setting a clause on the 6th playoff spot. If an independent or smaller conference team isn't in the top 15 (top 10?) then that spot could go to a P5 at-large.
How would this have shaken out over the past few years?
Here you go:
2015
1. Clemson
2. Alabama
3. Michigan State
4. Oklahoma
5. Stanford
6. Notre Dame (or Houston depending on if you count ND as an independent or ACC)
7. Iowa
8. Ohio State (or Notre Dame/FSU if you limit each conference to a max of two participants)
Notes: My guess would be that the committee would've gone ND at the 6 spot and FSU at the 8. Houston was ranked 14th overall in the AP poll after the conference championships, and I believe that the committee would've chosen ND.
2014
1. Alabama
2. Florida State
3. Oregon
4. Ohio State
5. Baylor
6. Boise State (or Mississippi State)
7. TCU
8. Michigan State
Notes: An argument can be made in years like this to use that 6th spot for an at-large instead of the best small conference/independent. If that were the case (since Boise was ranked 21), then Mississippi State would occupy the final at-large spot.
It should also be mentioned that this system would've fixed all of the Baylor & TCU debate of this season.
2013
1.Florida State
2. Auburn
3. Michigan State
4. Stanford
5. Baylor
6. UCF (or South Carolina, or Oregon)
7. Alabama
8. Ohio State
Notes: UCF was ranked 15th in the AP Poll after the conference championships. If the rule says they would have to be top 10, then we get South Carolina. If the rules also state no more than 2 per conference, then we would've had Oregon (Missouri was also ranked above Oregon, but we already have two SEC squads).
